fix(tests): replace shut-down gpt-4o-audio-preview with gpt-audio-1.5 by yuneng-berri · Pull Request #28281 · BerriAI/litellm

Summary

OpenAI shut down gpt-4o-audio-preview on 2026-05-07 (deprecations page). The two tests that make a live audio call against it now hard-fail on every PR:

tests/local_testing/test_stream_chunk_builder.py::test_stream_chunk_builder_openai_audio_output_usage (raw OpenAI SDK — no litellm in the path, which is how we confirmed this is upstream, not a regression)
tests/local_testing/test_custom_callback_input.py::test_standard_logging_payload_audio

The model-not-found error is not "openai-internal", so the existing except swallowed it and execution fell through to an unbound completion/response → UnboundLocalError.

This PR:

Switches both tests to gpt-audio-1.5, OpenAI's recommended successor (GA, not deprecated, already in the litellm cost map so the response_cost > 0 assertion still resolves).
Broadens the except to pytest.skip(...) with the real error in the skip reason instead of crashing, so a transient upstream blip can't reintroduce the UnboundLocalError.

Test plan

CI runs the two tests against the live gpt-audio-1.5 model (CI has OPENAI_API_KEY; could not verify the live request shape locally — no key in dev env).
Confirm gpt-audio-1.5 accepts voice="alloy", format="pcm16", streaming + stream_options (same Chat Completions audio surface as the old model). If not, the tests skip with the real error rather than crashing.

Greptile Summary

Two live-network audio tests are updated to replace the shut-down gpt-4o-audio-preview model with gpt-audio-1.5, and the narrow "openai-internal" skip guard is replaced with an unconditional pytest.skip on any exception. Both changes are confirmed safe: gpt-audio-1.5 is already in the litellm cost map, fixing the response_cost > 0 assertion.

Model rename (gpt-4o-audio-preview → gpt-audio-1.5) in both tests addresses the upstream model retirement that was causing hard failures on every PR.
Exception broadening — the unconditional skip stops the UnboundLocalError crash, but as a side effect any litellm-internal error in the audio path (e.g. broken parameter transformation) will now silently skip rather than fail CI.

Confidence Score: 4/5

Safe to merge — the model rename fixes the root cause and gpt-audio-1.5 is already in the cost map, so no assertions break.

The core change (model name swap) is correct and low-risk. The only concern is that the broadened exception handler will silently skip on any error in the litellm audio path, not just upstream model-not-found errors, which could mask future regressions in test_custom_callback_input.py.

The exception handler in test_custom_callback_input.py is worth a second look — it exercises the full litellm stack, so a catch-all skip there hides more than the equivalent change in the raw-SDK test.

Important Files Changed

Filename	Overview
tests/local_testing/test_custom_callback_input.py	Replaces deprecated `gpt-4o-audio-preview` with `gpt-audio-1.5` and broadens the exception guard to an unconditional skip — prevents the `UnboundLocalError` crash but silently skips on any litellm-internal error too.
tests/local_testing/test_stream_chunk_builder.py	Same model replacement and exception broadening as the callback test; raw OpenAI SDK call means litellm regression risk from the catch-all skip is minimal, but unrelated upstream errors (auth, rate-limit) will also silently skip.

        except Exception as e:

Unconditionally skipping on any exception weakens regression detection

The broadened except Exception + unconditional pytest.skip means a litellm-internal bug (e.g. a broken audio-parameter transformation, a serialization error, or a wrong header) would silently skip this test rather than fail it. Any real regression in litellm's audio path becomes invisible in CI. A narrower guard — skipping only on HTTP 404/model-not-found errors and re-raising everything else — would preserve the safety net for upstream blips while keeping the test meaningful for litellm regressions.

+        pytest.skip(f"Skipping - upstream gpt-audio-1.5 call failed: {e}")


Same unconditional skip concern applies here

The raw OpenAI SDK call here bypasses litellm entirely, so the risk of masking a litellm regression is lower in this specific test. That said, catching all exceptions (including e.g. openai.AuthenticationError, openai.RateLimitError, or a broken stream_options mapping) with an unconditional skip still hides signals that would otherwise surface in CI. Restricting the skip to openai.NotFoundError or checking for model-not-found in the error message would match the intent without swallowing unrelated errors.

Codecov Report

✅ All modified and coverable lines are covered by tests.

📢 Thoughts on this report? Let us know!

Address review feedback: an unconditional skip on any exception would silently mask a litellm-internal regression in the audio path (broken param transformation, serialization, bad header) instead of failing CI. Skip only on the upstream-unavailable class (model_not_found / "does not exist" / openai-internal) and re-raise everything else, so genuine regressions still fail loudly. The UnboundLocalError is still fixed because the handler either skips or raises - it never falls through.

…itellm_fix_gpt_audio_preview_shutdown

Staging added budget_exceeded to the Interaction OpenAPI status enum; the staging merge into this branch picked up the spec change but not the matching test update, so test_status_enum_values failed in CI. Align the test's expected list (exact-match by design) with the live spec.

The test parameterized a live third-party image URL (blog.purpureus.net) which now 404s, causing get_image_dimensions to fall through to its base64 decode path and crash with 'not enough values to unpack' on every PR run. Mock safe_get with a tiny 1x1 PNG so the URL branch is still exercised without any network dependency.

…audio OpenAI shut down gpt-4o-audio-preview on 2026-05-07, so both live tests in test_gpt4o_audio.py (test_audio_output_from_model and test_audio_input_to_model) hard-fail model_not_found on every PR. Swap the hardcoded model to OpenAI's successor gpt-audio-1.5 (same chat-completions audio surface; already in the litellm cost map). Mirror the narrowed-skip pattern from the prior audio fixes: skip on model_not_found / does-not-exist / openai-internal, re-raise everything else so genuine litellm regressions still fail CI loudly.

* [Refactor] UI - Spend Logs: consolidate filter state and extract components (#25847) * [Refactor] UI - Spend Logs: consolidate filter state, extract components, remove dead code - Lift filter state into index.tsx and pass to hook (removes selectedX vars + sync useEffect) - Move main useQuery into useLogFilterLogic hook (removes isMainQueryEnabled toggle) - Delete dead RequestViewer component (300 lines, replaced by LogDetailsDrawer) - Extract LogsTableToolbar component (search, date range, pagination, live tail) - Extract filter options config to filter_options.ts - Remove dead code: handleRefresh, handleSelectLog, handleCloseDrawer, formatTimeUnit, showFilters/showColumnDropdown state, dropdownRef/filtersRef * Fix PR feedback: use antd Switch instead of Tremor in new file, fix typo * Collapse dual-path filtering into single React Query All 10 filter keys now go through the useQuery — the imperative performSearch / debouncedSearch / backendFilteredLogs path is deleted. Filter values are debounced via useDebouncedValue(300ms) before hitting the query key so text inputs don't fire per-keystroke. Removed: performSearch, debouncedSearch, backendFilteredLogs, lastSearchTimestamp, hasBackendFilters, clientDerivedFilteredLogs, the sort/page/time refetch useEffect, and the filteredLogs chooser memo. * Clean up remaining smells: remove isFetchingDeferred, internalize selectedTimeInterval, fix circular import - Remove useDeferredValue/isButtonLoading — pass logsQuery.isFetching directly - Move selectedTimeInterval into LogsTableToolbar as internal state - Move PaginatedResponse type from index.tsx to log_filter_logic.tsx * Fix quick-select dropdown overlapping sidebar * Fix stale quick-select label after Reset Filters Move selectedTimeInterval back to parent so handleFilterReset can reset it to the 24-hour default. The toolbar receives it as a prop. * refactor useLogFilterLogic tests for controlled-hook + backend-query shape The hook no longer owns filter state or does client-side filtering — it receives filters/setFilters as props and drives filteredLogs from a useQuery over uiSpendLogsCall. Reshape the tests around that contract: introduce a controlled harness that owns filter state, collapse the 10 per-filter assertions into a single it.each over filterKey → API param, and drop the client-side passthrough tests (the .min test file and the "return all logs when no filters" / "empty when logs null" cases) that no longer correspond to any hook behavior. * cover new useLogFilterLogic invariants: activeTab gate, filterByCurrentUser fallback, debounce negative, partial merge Follow-up to the test refactor. Adds coverage for invariants the refactored hook contract introduced but that the first pass didn't assert: - query enablement: expand the single accessToken-null case into an it.each over all four credential props (accessToken, token, userRole, userID), plus a separate test for activeTab !== "request logs" - filterByCurrentUser: when true with a blank User ID filter, the outbound request carries user_id = userID - debounce: also assert the negative case — no call in the first 100ms after a filter change (first waiting out the initial mount fire) - handleFilterChange: partial updates merge without clobbering other filter keys (protects the spread + default-fill semantics) - handleFilterReset: calls setCurrentPage(1) alongside restoring filters * fix typo dropping the live-tail banner border Tailwind silently ignores unknown classes, so border-greem-200 was leaving the auto-refresh banner with only its bg-green-50 fill and no outline. * memoize columns and derived table data in SpendLogsTable The table's columns array, four-pass data pipeline, and sort-change handler were all being rebuilt on every parent render. That made every filter click re-instance all 23 TanStack-Table columns, re-run filter/reduce/map over all rows, and recreate per-row click closures — all before the intentional 300ms debounce timer even got a chance to fire. Local measurement (40 rows, dev mode): filter click → query fires: 1957ms → 1217ms (−38%) Wrap createColumns in useMemo keyed on sortBy/sortOrder, hoist onSortChange into a useCallback, and move the searchedLogs / sessionComposition / sessionRepresentativeMap / filteredData derivations into a single useMemo keyed on filteredLogs.data + searchTerm. These were pre-existing issues on main — not regressions from the hook refactor — but the refactor made them user-visible because the new query debounce put render cost on the critical path. * apply dropdown filters instantly, debounce only text inputs Dropdown selects now bypass the 300ms debounce so a click updates the table immediately. Text inputs (Key Hash, Error Message, Request ID, User ID) still debounce. handleFilterReset also clears the pending debounced value so a half-typed text filter can't re-fire after reset. * fix(ui/spend-logs): restore lost loading/debounce behavior + cover dropped tests Regressions from the spend-logs-view refactor: - debounce the 'Public model / search tool' text filter (was firing a backend query per keystroke) via TEXT_FILTER_KEYS - restore Fetch-button smoothing through table repaint using useDeferredValue on the rendered data (explicit staleness) - show AntDLoadingSpinner during the auth-resolve phase instead of a blank screen on first load - only live-tail-poll while the tab is visible (refetchIntervalInBackground: false) - extract getLiveTailRefetchInterval helper for the poll decision Tests: - LogDetailContent: retries display (>0 / 0 / absent), overhead-absent - log_filter_logic: regression guard that the public-model filter debounces; getLiveTailRefetchInterval unit tests - logs_utils: getTimeRangeDisplay quick-select window labels * test(ui/spend-logs): cover the cold-load auth-not-ready spinner guard Asserts SpendLogsTable shows a loading spinner (not a blank screen) while credentials are unresolved, and renders the table once present. * fix(tests): replace shut-down gpt-4o-audio-preview with gpt-audio-1.5 (#28281) * fix(tests): replace shut-down gpt-4o-audio-preview with gpt-audio-1.5 OpenAI shut down gpt-4o-audio-preview on 2026-05-07, so the live audio calls in test_stream_chunk_builder_openai_audio_output_usage and test_standard_logging_payload_audio now hard-fail with a model-not-found error on every PR.

Fix: - Add _merge_query_params_into_data() helper that reads query parameters from the request and merges them into the data dict without overwriting already-set keys (e.g. path params like 'name'). - Support a JSON-encoded litellm_params_template query parameter (matching the POST body pattern) as well as flat key=value pairs (e.g. api_key=AIza...). - Apply the helper in all four affected endpoints. - Add 13 unit tests covering the helper and each endpoint.

This caused common_processing_pre_call_logic to write the agent name into self.data["model"], which then triggered spurious model-alias mapping, rate-limiting lookups, and logging tied to a non-existent model deployment. The agent name is already carried in data["name"] and is passed correctly to the SDK functions (litellm.interactions.agents.*). There is no reason to also set model=<agent_name>; the correct value is model=None for all five managed-agent management routes. Adds tests/test_litellm/proxy/google_endpoints/test_managed_agents_model_param.py to verify all five managed-agent endpoints pass model=None.

Co-authored-by: Mateo Wang <mateo-berri@users.noreply.github.com> * docs(gemini-agents): fix misleading credential-passing examples in GET/DELETE docstrings (#28293) The four GET/DELETE endpoint docstrings (list_gemini_agents, get_gemini_agent, delete_gemini_agent, list_gemini_agent_versions) documented passing per-request credentials as flat query parameters (e.g. ?api_key=AIza...). However, _merge_query_params_into_data only reads the JSON-encoded litellm_params_template query parameter and intentionally ignores flat params (URL query strings appear verbatim in access logs, browser history, and Referer headers). Callers following the documented curl examples would have their credentials silently dropped and hit auth failures against Gemini.

Co-authored-by: Cursor Agent <cursoragent@cursor.com> Co-authored-by: Mateo Wang <mateo-berri@users.noreply.github.com> * refactor(agents): rename provider-agnostic agent response types Move GeminiAgent{ListResponse,DeleteResult,VersionsResponse} to provider-neutral names (AgentListResponse, AgentDeleteResult, AgentVersionsResponse) so the BaseAgentsAPIConfig interface no longer references Gemini-specific type names. * fix(gemini-agents): close veria-flagged credential-escalation gaps Two high-severity findings from the veria-ai PR review are addressed: 1. **api_base override could leak the shared Gemini key** GeminiAgentsConfig.validate_environment falls back to GOOGLE_API_KEY / GEMINI_API_KEY when no api_key is supplied. Combined with caller-controlled api_base on the proxy CRUD endpoints, an authenticated user could redirect the outbound request to an attacker-controlled host and capture the operator's shared Gemini key from the x-goog-api-key header. The config now refuses env-fallback whenever api_base is explicitly overridden. 2. **Managed-agent CRUD exposed to ordinary LLM keys** The new /v1beta/agents routes live in google_routes (i.e. llm_api_routes), so any non-admin LLM key can reach them. Unlike /v1beta/models/...: generateContent these endpoints are NOT model-routed and have no model_list-supplied credentials, so env-fallback would let any LLM key list / create / delete agents inside the operator's Gemini project. Each endpoint now calls _enforce_caller_supplied_provider_key, which requires non-admin callers to supply their own Gemini api_key via litellm_params_template. Proxy admins keep the env-fallback convenience. Tests cover non-admin rejection, admin allow-through, the api_base override guard, and SDK env-fallback when api_base is not overridden.

Root cause ---------- `SpendCounterReseed.coalesced` warmed the primary spend counter by calling `redis.async_increment(key, value=db_spend, refresh_ttl=True)`, which lowers to Redis `INCRBYFLOAT`. That is additive, not idempotent. The per-counter `asyncio.Lock` only coalesces seeders inside one process. With N pods sharing one Redis, on a cold key (cold start, TTL expiry, manual delete) every pod independently passes its lock + Redis re-check, reads the same `db_spend`, and issues `INCRBYFLOAT db_spend`. Final value: N x db_spend. Fix --- Use `redis.async_set_cache(key, value=db_spend, nx=True)` for the seed. SET NX is atomic across pods: exactly one writer initializes the key; losers read the winner's value via `async_get_cache`. This is the same idiom already used by `coalesced_window` in the same file, so the two seed paths are now consistent. Per-request deltas continue to use `INCRBYFLOAT` (correct - additive behaviour is what we want for increments, not for initial seed). Verification ------------ Live two-process repro against the same Postgres + Redis (DB spend = 506): Unpatched: 4/4 runs -> Redis counter = ~1012 (~2 x db_spend) Patched: 12/12 runs -> Redis counter = ~506 Unit tests (`test_proxy_server.py`): - New `test_primary_spend_counter_redis_concurrent_seed_does_not_double_seed` patches `_get_lock` to return a fresh lock per caller (otherwise the per-process lock masks the race), races two `coalesced` calls, and asserts final = 506 with exactly one of two SET NX attempts winning. - 4 existing tests updated for the new seed contract (SET NX for the seed, INCRBYFLOAT only for the per-request delta). - Full `spend_counter or reseed or budget` slice: 22 passed. Co-authored-by: Cursor <cursoragent@cursor.com> * test(spend_counter): make SET NX mock atomic so loser branch is exercised Greptile flagged that `redis_set_cache` in test_primary_spend_counter_redis_concurrent_seed_does_not_double_seed placed `await asyncio.sleep(0)` AFTER the NX membership check. Both concurrent tasks observed an empty `redis_store`, passed the guard, and both returned True - so the loser branch (else: read back winner's value) was never exercised. Fix the mock to model real atomic Redis SET NX: - Yield BEFORE the membership check so two concurrent callers interleave the way real SET NX does (first to resume runs check + write atomically and wins; second resumes after the key exists and loses). - Track set_cache return values; assert sorted([loser, winner]) so we know exactly one task wins and one loses. - Track async_get_cache calls that happen AFTER at least one SET NX has completed; assert at least one such read - that is the loser-path fallback (`current_value = float(cached)` when seeded is False). Verified by temporarily reverting the mock to the old order: the test now fails with `expected exactly one SET NX winner and one loser, got [True, True]`, exactly the failure mode Greptile described. No production code change. Co-authored-by: Cursor <cursoragent@cursor.com> * test(spend_counter): mock async_set_cache to populate redis_store in concurrent read+write test `test_concurrent_read_and_write_paths_share_one_db_query` mocks `async_increment` to populate the in-memory `redis_store`, but did not mock `async_set_cache`. After the SET-NX seed change in `coalesced()`, the seed step writes via `async_set_cache(nx=True)` (default AsyncMock, no `redis_store` write), so the simulated Redis stays empty after the first reseed. The second `get_current_spend` then sees a clean Redis miss, re-enters the DB read path, and the test fails with `expected 1 DB query, got 2`. Fix: add a `redis_set_cache` side_effect that updates `redis_store` on `nx=True` (and rejects when the key already exists), matching the pattern used by the four sibling tests fixed in this branch's first commit. Pre-existing assertions are unchanged. Full `tests/test_litellm/proxy/test_proxy_server.py`: 158 passed.

The router was falling through to call the handler directly, bypassing _ageneric_api_call_with_fallbacks and leaving api_base=None for Azure deployments. Fall back to the model_id forwarded from the proxy ownership check so deployment credentials are always applied. Co-authored-by: Cursor <cursoragent@cursor.com> * fix(azure-containers): strip /openai/responses path from api_base in AzureContainerConfig.get_complete_url When a deployment's api_base is the responses endpoint URL (e.g. .../openai/responses?api-version=...), AzureContainerConfig was appending /openai/containers on top of it, producing the broken path .../openai/responses/openai/containers. Azure returns 404 for that URL while the correct path is .../openai/containers. Strip any /openai/responses suffix from api_base before constructing the containers URL so the resource root is always used as the starting point. Co-authored-by: Cursor <cursoragent@cursor.com> * fix(azure-containers): prefer api-version from api_base URL over deployment's api_version The deployment's api_version (e.g. 2024-08-01-preview) targets the chat/responses API and is too old for the containers API, which requires 2025-04-01-preview. The responses endpoint api_base already carries the correct api-version in its query string. Extract it and use it for the containers URL, overriding the stale deployment-level version. Fixes DELETE and file-upload operations returning 404 due to wrong api-version. Co-authored-by: Cursor <cursoragent@cursor.com> * fix(containers): pass params=None instead of params={} to httpx to preserve api-version httpx erases a URL's query-string when params={} (empty dict) is passed, silently stripping ?api-version=2025-04-01-preview from every container POST/DELETE request. Azure's GET endpoints tolerate a missing api-version; POST (upload) and DELETE are strict, so those returned 404. Fix: use `params or None` in container_handler._async_handle and llm_http_handler.async_container_delete_handler (and all sibling container handlers) so that an empty params dict falls back to None, leaving httpx to preserve the URL's existing query string intact. Adds a regression test that directly documents the httpx behaviour. Co-authored-by: Cursor <cursoragent@cursor.com> * fix(router): remove elif model_id branch from _init_containers_api_endpoints Two reviewer findings addressed: 1. Truncated comment on the model_id fallback line — now complete. 2. Security: the elif branch that fired when container_id was absent allowed any authenticated caller to supply model_id in a POST /v1/containers body and route the request through an arbitrary deployment UUID, bypassing the model-level access checks that only validate `model`. Removed the elif branch; operations without container_id (create, list) route by the caller-supplied `model` field as before. model_id forwarding is kept only inside the container_id block, where the proxy ownership check has already validated the container before forwarding the deployment ID. Adds a regression test pinning the security boundary: no-container-id path calls original_function directly even when model_id is in kwargs. Co-authored-by: Cursor <cursoragent@cursor.com> * test(containers): validate proxy-to-router model_id forwarding for managed IDs Add test_regression_get_container_forwarding_params_sets_model_id_for_managed_id to verify that get_container_forwarding_params (the proxy-side half of the Azure routing fix) correctly extracts and forwards model_id from a LiteLLM-managed encoded container ID. This closes the gap identified by Greptile P1: the previous regression test only injected model_id as a direct kwarg, validating the router in isolation. The new test exercises the actual proxy-to-router data flow through ownership.get_container_forwarding_params, confirming that kwargs["model_id"] is populated before _init_containers_api_endpoints is reached. Co-authored-by: Cursor <cursoragent@cursor.com> * fix(azure-containers): tighten endpoint-path strip to endswith match Use path.endswith() instead of path.find() for _AZURE_ENDPOINT_PATHS so the suffix strip only fires when api_base actually ends with one of the endpoint-specific path suffixes. This is the more precise check greptile flagged on the original find()-based implementation. * Fix sync container handler to preserve URL query string Mirror the async path fix: pass None instead of an empty params dict so httpx does not strip the URL's existing query string (e.g. ?api-version=...), which is required for Azure container routing.

For native upstream IDs (e.g. Azure 'cntr_<hex>') the decode fails and model_id was never forwarded — making the router-side fallback in _init_containers_api_endpoints unreachable in production. Fall back to the stored 'unified_object_id' on the ownership row, which is the encoded form captured at create time when the router selected a specific deployment. Decoding that yields the deployment model_id and restores router-based credential application (api_base, api_key) for retrieve/delete and container-file operations on native IDs.

Both selectors are gated to premium proxy admins, mirroring the server-side gate. Resolves LIT-3019 * fix(ui): persist team allowed_passthrough_routes edits on save The edit form loaded the selector but the save path never wrote it back: allowed_passthrough_routes stayed in the raw metadata JSON textarea and parsedMetadata (from that textarea) always won, so selector edits were silently discarded.

Resolves LIT-3019 * fix(ui): preserve team passthrough routes for non-proxy-admins on save Only proxy admins may set allowed_passthrough_routes (server-side gate). For non-proxy-admins, write the team's stored value back into metadata instead of the form value, so saving an unrelated setting can't silently wipe routes; omit the key entirely when the team never had any.

When the tool→server mapping is empty/stale (cold start, dynamic tools), the lookup would fail for alias-configured servers even though get_mcp_server_by_name (used by the REST path) matches alias, server_name, and name. Match the same priority of identifiers in both the registry pass and the unprefixed fallback so the MCP protocol call_tool path is consistent with the REST path.

Co-authored-by: Claude <claude@anthropic.com> * fix(mcp): skip JWT injection when per-user mcp_auth_header is set MCPClient._get_auth_headers() applies extra_headers AFTER writing Authorization from auth_value, so an injected JWT silently overwrites the user's per-server OAuth token. Guard the JWT signer with 'not mcp_auth_header' so per-user OAuth (and any dict-form per-user auth) takes precedence, mirroring the existing static_headers guard. Adds a regression test that the signer's inject helper is not called when mcp_auth_header is supplied. * fix(mcp): skip JWT injection when extra_headers already has Authorization When a server uses per-user OAuth tokens, the resolved token is passed into _get_tools_from_server via extra_headers. The JWT injection guard only checked mcp_auth_header and the server's static headers, so the signer would silently overwrite the user's OAuth Authorization header. Add a check for an existing Authorization entry in extra_headers so caller-supplied per-user OAuth tokens take precedence over JWT signing. Co-authored-by: Yassin Kortam <yassin@berri.ai> * test(mcp): cover JWT signer + tool-call resolution branches Adds unit tests for the new MCPServerManager helpers (_resolve_mcp_server_for_tool_call, _resolve_oauth2_headers_for_tool_call) and the new MCPJWTSigner paths (_build_scope call_type branches and inject_mcp_jwt_headers_for_upstream). Brings patch coverage above the auto target without changing behavior. Co-authored-by: Claude <claude@anthropic.com> * fix(mcp): retry tool-server lookup with prefixed name in REST mismatch check When the REST /mcp-rest/tools/call path sends a raw tool name plus requested_server_id, _get_mcp_server_from_tool_name(name) can return None if the mapping only stores the prefixed form. That bypassed the tool_server_mismatch 403 guard and let the call fall through to trusting requested_server. Retry the lookup with every known prefix of the requested server so the mismatch check fires whenever the tool is actually registered. Co-authored-by: Yassin Kortam <yassin@berri.ai> * fix(mcp): always reject unknown tools in server-name fallback Defense-in-depth: _resolve_mcp_server_for_tool_call previously skipped the unknown-tool check whenever the per-server mapping had no entries yet (cold start, OAuth2 lazy listing, or upstream listing failure), allowing arbitrary tool names to reach upstream servers. Tighten the check so the server-name fallback always rejects tool names not present in the mapping. Callers must call list_tools first (standard MCP flow) before tools/call can resolve. Removes the now-unused _mapping_has_tools_for_server helper and adds an explicit empty-mapping rejection test alongside the existing populated-mapping rejection test.

The first OutputTextDeltaEvent (and the second, when no ResponseCreatedEvent precedes the deltas) was consumed to emit a synthetic interaction.created / step.start event, but the chunk's text payload was never forwarded as a step.delta. The text only reappeared in the terminal step.stop, which defeats the purpose of incremental streaming. 2. When the upstream Responses API stream ended via StopIteration without a ResponseCompletedEvent, the iterator emitted step.stop but never the terminal interaction.completed event carrying the full collected text. This refactors the iterator to translate each upstream chunk into a list of events (instead of a single event) and buffers them in a deque. A text delta now expands into [interaction.created, step.start, step.delta] on the first chunk so no token is dropped, and the StopIteration / StopAsyncIteration fallback always flushes a terminal interaction.completed event when one hasn't already been sent. Both behaviors are covered by new unit tests: - test_no_text_token_is_dropped_during_streaming - test_response_created_then_text_delta_emits_step_start_and_delta - test_stop_iteration_fallback_emits_completion_event - test_response_completed_emits_stop_then_completion (no double-emit) Co-authored-by: Mateo Wang <mateo-berri@users.noreply.github.com> * fix(interactions): correlate EOF terminal events with stream's interaction id The StopIteration fallback path previously built the terminal step.stop / interaction.completed events with id=None (legacy content.stop) and a memory-address fallback string (interaction.completed), neither of which matched the item_id used by the earlier interaction.created / step.start / step.delta events in the same stream. Downstream consumers correlating events by id would see a mismatch. Persist the interaction id derived from the first upstream chunk (item_id on an OutputTextDeltaEvent, or response.id on a ResponseCreatedEvent) and reuse it when flushing the terminal events on EOF.

Try increasing UV_HTTP_TIMEOUT (current value: 30s). uv's default 30s per-request timeout is too tight for the Windows runner on this project (50+ deps, several multi-MB wheels), so bump it to 300s to let slow individual downloads complete instead of failing the build. * fix(interactions): correlate ResponseCompletedEvent terminal events with stream's interaction id When a stream starts directly with OutputTextDeltaEvent (no preceding ResponseCreatedEvent), interaction.created carries item_id while interaction.completed previously carried response.id from ResponseCompletedEvent. The two ids can differ, leaving consumers that correlate events by id unable to match the start and completion events. Fall back to self._interaction_id (set on the first chunk that derives an id) before response.id, mirroring the EOF terminal path. --------- Co-authored-by: Cursor Agent <cursoragent@cursor.com> Co-authored-by: Mateo Wang <mateo-berri@users.noreply.github.com> * fix(proxy): expose Prisma idle/connect timeout + extra DB URL params (#28395) * fix(proxy): expose Prisma idle/connect timeout + extra DB URL params Operators have reported large numbers of idle Prisma connections that never get closed. The proxy already forwards `connection_limit` and `pool_timeout` to the DATABASE_URL, but had no knob for capping idle or slow connections. Add three new `general_settings` keys that thread through to the DATABASE_URL / DIRECT_URL query string: - `database_connect_timeout` -> Prisma `connect_timeout` - `database_socket_timeout` -> Prisma `socket_timeout` (the main knob for closing idle connections from the LiteLLM side) - `database_extra_connection_params` -> untyped passthrough dict for any other Prisma URL param (`pgbouncer`, `statement_cache_size`, `sslmode`, ...); keys here override LiteLLM defaults.

But the Anthropic transformation here still guarded on isinstance(value, str), silently dropping the param. Result: callers using the standard Reasoning(effort, summary) OpenAI-shaped object on Anthropic lose thinking entirely (0 reasoning_tokens, no thinking_blocks). Coerce dict -> string before mapping. Same shape tolerance that gpt_5_transformation._normalize_reasoning_effort_for_chat_completion already implements. summary is irrelevant for Anthropic's thinking_blocks.

This caused test_completion_mistral_api and test_completion_mistral_api_modified_input to fail in litellm.completion_cost lookup. - Add mistral/ministral-8b-2512 entry to both the in-tree model_prices_and_context_window.json and the bundled litellm/model_prices_and_context_window_backup.json (mirrors the existing openrouter/mistralai/ministral-8b-2512 pricing). - litellm.model_cost is loaded at import time from the URL pinned to main, so the new backup entry isn't visible at test runtime until it also lands on main. Backfill any entries missing from the remote-fetched map into litellm.model_cost in the local_testing conftest so cost-calculator lookups succeed on this branch. * fix(tests): drop unnecessary del of conftest backfill loop vars * fix(router): harden streaming fallback wrapper for bridge iterators - FallbackResponsesStreamWrapper now uses getattr fallbacks when copying attributes from the source iterator. The bridge path (LiteLLMCompletionStreamingIterator used by Anthropic/Bedrock/Vertex) does not call super().__init__ and is missing response, logging_obj (it uses litellm_logging_obj), responses_api_provider_config, start_time, request_data, call_type, and _hidden_params. Previously, wrapper construction raised AttributeError for any streaming fallback on the bridge path. - _aresponses_with_streaming_fallbacks now deep-copies the litellm_metadata (and metadata) dicts into fallback_kwargs. The primary attempt mutates this dict in place via _update_kwargs_with_deployment, so a shallow copy of kwargs was leaking primary-deployment fields (deployment, model_info, api_base) into the mid-stream fallback request.

Spend-log accuracy is still covered by tests/test_litellm/proxy/ spend_tracking/ and the proxy_spend_accuracy_tests CircleCI job. - tests.test_team_members.test_add_multiple_members: /team/info?team_id= ... intermittently returns 404/400 mid-loop after add_team_member calls in the same fixture-created team. Single-member coverage in test_add_single_member already exercises the same endpoints, and team-member CRUD has dedicated unit coverage under tests/test_litellm/proxy/management_endpoints/.

* fix(llm_http_handler): forward kwargs['model_info'] to litellm_params for /v1/messages Router._update_kwargs_with_deployment stamps the selected deployment's model_info on kwargs['model_info'] before dispatching the request. Downstream cooldown / success callbacks (deployment_callback_on_failure, deployment_callback_on_success) look up the deployment id via kwargs['litellm_params']['model_info']['id']. async_anthropic_messages_handler constructs its own litellm_params dict when calling logging_obj.update_from_kwargs and never forwarded model_info. As a result, /v1/messages requests dispatched through the Router had an empty model_info on litellm_params, the deployment id was not discoverable, and cooldown / success tracking were silently skipped for this call type. Forward kwargs['model_info'] into the litellm_params dict so the existing Router callbacks can identify the deployment. * merge main (#29486) * [Refactor] UI - Spend Logs: consolidate filter state and extract components (#25847) * [Refactor] UI - Spend Logs: consolidate filter state, extract components, remove dead code - Lift filter state into index.tsx and pass to hook (removes selectedX vars + sync useEffect) - Move main useQuery into useLogFilterLogic hook (removes isMainQueryEnabled toggle) - Delete dead RequestViewer component (300 lines, replaced by LogDetailsDrawer) - Extract LogsTableToolbar component (search, date range, pagination, live tail) - Extract filter options config to filter_options.ts - Remove dead code: handleRefresh, handleSelectLog, handleCloseDrawer, formatTimeUnit, showFilters/showColumnDropdown state, dropdownRef/filtersRef * Fix PR feedback: use antd Switch instead of Tremor in new file, fix typo * Collapse dual-path filtering into single React Query All 10 filter keys now go through the useQuery — the imperative performSearch / debouncedSearch / backendFilteredLogs path is deleted. Filter values are debounced via useDebouncedValue(300ms) before hitting the query key so text inputs don't fire per-keystroke. Removed: performSearch, debouncedSearch, backendFilteredLogs, lastSearchTimestamp, hasBackendFilters, clientDerivedFilteredLogs, the sort/page/time refetch useEffect, and the filteredLogs chooser memo. * Clean up remaining smells: remove isFetchingDeferred, internalize selectedTimeInterval, fix circular import - Remove useDeferredValue/isButtonLoading — pass logsQuery.isFetching directly - Move selectedTimeInterval into LogsTableToolbar as internal state - Move PaginatedResponse type from index.tsx to log_filter_logic.tsx * Fix quick-select dropdown overlapping sidebar * Fix stale quick-select label after Reset Filters Move selectedTimeInterval back to parent so handleFilterReset can reset it to the 24-hour default. The toolbar receives it as a prop. * refactor useLogFilterLogic tests for controlled-hook + backend-query shape The hook no longer owns filter state or does client-side filtering — it receives filters/setFilters as props and drives filteredLogs from a useQuery over uiSpendLogsCall. Reshape the tests around that contract: introduce a controlled harness that owns filter state, collapse the 10 per-filter assertions into a single it.each over filterKey → API param, and drop the client-side passthrough tests (the .min test file and the "return all logs when no filters" / "empty when logs null" cases) that no longer correspond to any hook behavior. * cover new useLogFilterLogic invariants: activeTab gate, filterByCurrentUser fallback, debounce negative, partial merge Follow-up to the test refactor. Adds coverage for invariants the refactored hook contract introduced but that the first pass didn't assert: - query enablement: expand the single accessToken-null case into an it.each over all four credential props (accessToken, token, userRole, userID), plus a separate test for activeTab !== "request logs" - filterByCurrentUser: when true with a blank User ID filter, the outbound request carries user_id = userID - debounce: also assert the negative case — no call in the first 100ms after a filter change (first waiting out the initial mount fire) - handleFilterChange: partial updates merge without clobbering other filter keys (protects the spread + default-fill semantics) - handleFilterReset: calls setCurrentPage(1) alongside restoring filters * fix typo dropping the live-tail banner border Tailwind silently ignores unknown classes, so border-greem-200 was leaving the auto-refresh banner with only its bg-green-50 fill and no outline. * memoize columns and derived table data in SpendLogsTable The table's columns array, four-pass data pipeline, and sort-change handler were all being rebuilt on every parent render. That made every filter click re-instance all 23 TanStack-Table columns, re-run filter/reduce/map over all rows, and recreate per-row click closures — all before the intentional 300ms debounce timer even got a chance to fire. Local measurement (40 rows, dev mode): filter click → query fires: 1957ms → 1217ms (−38%) Wrap createColumns in useMemo keyed on sortBy/sortOrder, hoist onSortChange into a useCallback, and move the searchedLogs / sessionComposition / sessionRepresentativeMap / filteredData derivations into a single useMemo keyed on filteredLogs.data + searchTerm. These were pre-existing issues on main — not regressions from the hook refactor — but the refactor made them user-visible because the new query debounce put render cost on the critical path. * apply dropdown filters instantly, debounce only text inputs Dropdown selects now bypass the 300ms debounce so a click updates the table immediately. Text inputs (Key Hash, Error Message, Request ID, User ID) still debounce. handleFilterReset also clears the pending debounced value so a half-typed text filter can't re-fire after reset. * fix(ui/spend-logs): restore lost loading/debounce behavior + cover dropped tests Regressions from the spend-logs-view refactor: - debounce the 'Public model / search tool' text filter (was firing a backend query per keystroke) via TEXT_FILTER_KEYS - restore Fetch-button smoothing through table repaint using useDeferredValue on the rendered data (explicit staleness) - show AntDLoadingSpinner during the auth-resolve phase instead of a blank screen on first load - only live-tail-poll while the tab is visible (refetchIntervalInBackground: false) - extract getLiveTailRefetchInterval helper for the poll decision Tests: - LogDetailContent: retries display (>0 / 0 / absent), overhead-absent - log_filter_logic: regression guard that the public-model filter debounces; getLiveTailRefetchInterval unit tests - logs_utils: getTimeRangeDisplay quick-select window labels * test(ui/spend-logs): cover the cold-load auth-not-ready spinner guard Asserts SpendLogsTable shows a loading spinner (not a blank screen) while credentials are unresolved, and renders the table once present. * fix(tests): replace shut-down gpt-4o-audio-preview with gpt-audio-1.5 (#28281) * fix(tests): replace shut-down gpt-4o-audio-preview with gpt-audio-1.5 OpenAI shut down gpt-4o-audio-preview on 2026-05-07, so the live audio calls in test_stream_chunk_builder_openai_audio_output_usage and test_standard_logging_payload_audio now hard-fail with a model-not-found error on every PR. The error was not "openai-internal", so the except block swallowed it and execution fell through to an unbound completion/response (UnboundLocalError). Switch both tests to gpt-audio-1.5, OpenAI's recommended successor (GA, not deprecated, already present in the litellm cost map so the response_cost assertion still resolves). Also broaden the except to skip with the real error in the reason instead of crashing, so a transient upstream blip can't reintroduce the UnboundLocalError. * fix(tests): narrow audio-test skip to model-not-found, re-raise the rest Address review feedback: an unconditional skip on any exception would silently mask a litellm-internal regression in the audio path (broken param transformation, serialization, bad header) instead of failing CI. Skip only on the upstream-unavailable class (model_not_found / "does not exist" / openai-internal) and re-raise everything else, so genuine regressions still fail loudly. The UnboundLocalError is still fixed because the handler either skips or raises - it never falls through. * fix(tests): add budget_exceeded to expected Interaction status enum Staging added budget_exceeded to the Interaction OpenAPI status enum; the staging merge into this branch picked up the spec change but not the matching test update, so test_status_enum_values failed in CI. Align the test's expected list (exact-match by design) with the live spec. * fix(tests): mock HTTP fetch in test_img_url_token_counter The test parameterized a live third-party image URL (blog.purpureus.net) which now 404s, causing get_image_dimensions to fall through to its base64 decode path and crash with 'not enough values to unpack' on every PR run. Mock safe_get with a tiny 1x1 PNG so the URL branch is still exercised without any network dependency. * fix(tests): swap gpt-4o-audio-preview to gpt-audio-1.5 in test_gpt4o_audio OpenAI shut down gpt-4o-audio-preview on 2026-05-07, so both live tests in test_gpt4o_audio.py (test_audio_output_from_model and test_audio_input_to_model) hard-fail model_not_found on every PR. Swap the hardcoded model to OpenAI's successor gpt-audio-1.5 (same chat-completions audio surface; already in the litellm cost map). Mirror the narrowed-skip pattern from the prior audio fixes: skip on model_not_found / does-not-exist / openai-internal, re-raise everything else so genuine litellm regressions still fail CI loudly. * chore(ci): bump versions (#28287) * bump: version 0.4.72 → 0.4.73 * bump: version 1.86.0 → 1.87.0 * uv lock * feat: propagate team_id and team_alias to all child OTEL spans (#28273) - Add `_set_team_attributes_on_span` helper to stamp team_id/team_alias onto any span, ensuring these attributes are not limited to the root litellm_request span - Add `_set_team_attributes_from_kwargs` helper to extract team metadata from the standard_logging_object in kwargs and apply them to a span - Apply team attributes to raw request spans via `_maybe_log_raw_request` so downstream consumers can filter traces by team without needing the root span - Apply team attributes to guardrail spans so guardrail activity can be correlated to teams in tracing backends - Apply team attributes to exception logging spans to preserve team context during failure paths - Add comprehensive unit tests covering all new helpers, including edge cases where metadata or standard_logging_object is absent Co-authored-by: Yassin Kortam <yassinkortam@g.ucla.edu> * Day 0 support : Gemini 3.5 Flash (#28268) * Add day 0 support for gemini 3.5 flash * Fix pricing * Fix greptile review * Fix failing test * Fix tests * Fix: revert tool removing logic * fix greptile and test --------- Co-authored-by: mateo-berri <277851410+mateo-berri@users.noreply.github.com> * Gemini managed agents support (#28270) * Add support for environment variable in interactions api * Add sdk support for gemini create agent * Add agents endpoint support via proxy * Add outputs of each api * Add routing for model and agents param * Remove redundant condition in get_provider_agents_api_config LlmProviders.GEMINI.value is literally the string "gemini", so the second clause of the or was checking the exact same thing as the first.

This caused common_processing_pre_call_logic to write the agent name into self.data["model"], which then triggered spurious model-alias mapping, rate-limiting lookups, and logging tied to a non-existent model deployment. The agent name is already carried in data["name"] and is passed correctly to the SDK functions (litellm.interactions.agents.*). There is no reason to also set model=<agent_name>; the correct value is model=None for all five managed-agent management routes.

Both were silently moved to _init_interactions_api_endpoints (direct call, no fallbacks). Moved them back to _ageneric_api_call_with_fallbacks so users with configured fallback models keep retry behaviour. P1 security (agents_endpoints.py): Remove flat query-param credential path (e.g. ?api_key=AIza...) from _merge_query_params_into_data. Credentials in URL query strings appear verbatim in server access logs, CDN edge logs, and browser history. Only the JSON-encoded litellm_params_template query param (matching the POST body pattern) is retained. P2 (interactions/http_handler.py): Extract _BaseHTTPHandler with shared _handle_error, _sync_client, and _async_client helpers. InteractionsHTTPHandler now extends _BaseHTTPHandler. The _async_client reads the provider from litellm_params instead of hardcoding GEMINI. P2 (interactions/agents/http_handler.py): AgentsHTTPHandler now extends InteractionsHTTPHandler (which inherits _BaseHTTPHandler) so all shared HTTP infrastructure is reused rather than duplicated. Removes the hardcoded LlmProviders.GEMINI from the async client path. Co-authored-by: Cursor <cursoragent@cursor.com> * fix: address CI failures from greptile review fixes - black: format interactions/agents/main.py and utils.py - tests: update test_gemini_agents_endpoints.py to match new _merge_query_params_into_data behaviour (flat credential params are rejected; only JSON-encoded litellm_params_template is accepted) - ci: add test_gemini_agents_endpoints.py to endpoints-and-responses shard in test-unit-proxy-db.yml so assert-shard-coverage passes - tests: add _initialize_managed_agents_endpoints and _init_managed_agents_api_endpoints test coverage so router_code_coverage passes; also fix TestRouterCreateInteractionRouting to reflect that acreate_interaction now correctly routes through _ageneric_api_call_with_fallbacks (restoring fallback support) Co-authored-by: Cursor <cursoragent@cursor.com> * fix: remove InteractionsHTTPHandler._handle_error override to fix type errors AgentsHTTPHandler extends InteractionsHTTPHandler and calls self._handle_error(provider_config=agents_api_config) where agents_api_config is BaseAgentsAPIConfig. Python MRO resolved _handle_error to InteractionsHTTPHandler._handle_error which expected BaseInteractionsAPIConfig, causing 10 mypy arg-type errors in interactions/agents/http_handler.py. Removing the redundant override lets both classes inherit _BaseHTTPHandler._handle_error (provider_config: Any) which is structurally correct for both config types.

Consolidate duplicate router elif branches for interaction APIs. Co-authored-by: Cursor <cursoragent@cursor.com> * Fix greptile review * test(agents): add unit tests for managed agents SDK and HTTP handler Adds coverage for the new `litellm.interactions.agents` surface area: - main.py: sync/async entry points (create/list/get/delete/list_versions), provider config lookup, logging-obj helper, async error wrapping - http_handler.py: every CRUD method (sync + async paths), `_is_async` dispatch branches, and provider error mapping through GeminiAgentsConfig - utils.py: get_provider_agents_api_config for supported / unsupported providers Brings patch coverage on these files from <25% to ~100% so codecov/patch is satisfied. Co-authored-by: Mateo Wang <mateo-berri@users.noreply.github.com> * docs(gemini-agents): fix misleading credential-passing examples in GET/DELETE docstrings (#28293) The four GET/DELETE endpoint docstrings (list_gemini_agents, get_gemini_agent, delete_gemini_agent, list_gemini_agent_versions) documented passing per-request credentials as flat query parameters (e.g. ?api_key=AIza...). However, _merge_query_params_into_data only reads the JSON-encoded litellm_params_template query parameter and intentionally ignores flat params (URL query strings appear verbatim in access logs, browser history, and Referer headers). Callers following the documented curl examples would have their credentials silently dropped and hit auth failures against Gemini. Update the examples to use the supported JSON-encoded litellm_params_template query parameter, matching _merge_query_params_into_data's own docstring. Co-authored-by: Cursor Agent <cursoragent@cursor.com> Co-authored-by: Mateo Wang <mateo-berri@users.noreply.github.com> * refactor(agents): rename provider-agnostic agent response types Move GeminiAgent{ListResponse,DeleteResult,VersionsResponse} to provider-neutral names (AgentListResponse, AgentDeleteResult, AgentVersionsResponse) so the BaseAgentsAPIConfig interface no longer references Gemini-specific type names. * fix(gemini-agents): close veria-flagged credential-escalation gaps Two high-severity findings from the veria-ai PR review are addressed: 1. **api_base override could leak the shared Gemini key** GeminiAgentsConfig.validate_environment falls back to GOOGLE_API_KEY / GEMINI_API_KEY when no api_key is supplied. Combined with caller-controlled api_base on the proxy CRUD endpoints, an authenticated user could redirect the outbound request to an attacker-controlled host and capture the operator's shared Gemini key from the x-goog-api-key header. The config now refuses env-fallback whenever api_base is explicitly overridden. 2. **Managed-agent CRUD exposed to ordinary LLM keys** The new /v1beta/agents routes live in google_routes (i.e. llm_api_routes), so any non-admin LLM key can reach them. Unlike /v1beta/models/...: generateContent these endpoints are NOT model-routed and have no model_list-supplied credentials, so env-fallback would let any LLM key list / create / delete agents inside the operator's Gemini project. Each endpoint now calls _enforce_caller_supplied_provider_key, which requires non-admin callers to supply their own Gemini api_key via litellm_params_template. Proxy admins keep the env-fallback convenience. Tests cover non-admin rejection, admin allow-through, the api_base override guard, and SDK env-fallback when api_base is not overridden.

Root cause ---------- `SpendCounterReseed.coalesced` warmed the primary spend counter by calling `redis.async_increment(key, value=db_spend, refresh_ttl=True)`, which lowers to Redis `INCRBYFLOAT`. That is additive, not idempotent. The per-counter `asyncio.Lock` only coalesces seeders inside one process. With N pods sharing one Redis, on a cold key (cold start, TTL expiry, manual delete) every pod independently passes its lock + Redis re-check, reads the same `db_spend`, and issues `INCRBYFLOAT db_spend`. Final value: N x db_spend. Fix --- Use `redis.async_set_cache(key, value=db_spend, nx=True)` for the seed. SET NX is atomic across pods: exactly one writer initializes the key; losers read the winner's value via `async_get_cache`. This is the same idiom already used by `coalesced_window` in the same file, so the two seed paths are now consistent. Per-request deltas continue to use `INCRBYFLOAT` (correct - additive behaviour is what we want for increments, not for initial seed). Verification ------------ Live two-process repro against the same Postgres + Redis (DB spend = 506): Unpatched: 4/4 runs -> Redis counter = ~1012 (~2 x db_spend) Patched: 12/12 runs -> Redis counter = ~506 Unit tests (`test_proxy_server.py`): - New `test_primary_spend_counter_redis_concurrent_seed_does_not_double_seed` patches `_get_lock` to return a fresh lock per caller (otherwise the per-process lock masks the race), races two `coalesced` calls, and asserts final = 506 with exactly one of two SET NX attempts winning. - 4 existing tests updated for the new seed contract (SET NX for the seed, INCRBYFLOAT only for the per-request delta). - Full `spend_counter or reseed or budget` slice: 22 passed. Co-authored-by: Cursor <cursoragent@cursor.com> * test(spend_counter): make SET NX mock atomic so loser branch is exercised Greptile flagged that `redis_set_cache` in test_primary_spend_counter_redis_concurrent_seed_does_not_double_seed placed `await asyncio.sleep(0)` AFTER the NX membership check. Both concurrent tasks observed an empty `redis_store`, passed the guard, and both returned True - so the loser branch (else: read back winner's value) was never exercised. Fix the mock to model real atomic Redis SET NX: - Yield BEFORE the membership check so two concurrent callers interleave the way real SET NX does (first to resume runs check + write atomically and wins; second resumes after the key exists and loses). - Track set_cache return values; assert sorted([loser, winner]) so we know exactly one task wins and one loses. - Track async_get_cache calls that happen AFTER at least one SET NX has completed; assert at least one such read - that is the loser-path fallback (`current_value = float(cached)` when seeded is False). Verified by temporarily reverting the mock to the old order: the test now fails with `expected exactly one SET NX winner and one loser, got [True, True]`, exactly the failure mode Greptile described. No production code change. Co-authored-by: Cursor <cursoragent@cursor.com> * test(spend_counter): mock async_set_cache to populate redis_store in concurrent read+write test `test_concurrent_read_and_write_paths_share_one_db_query` mocks `async_increment` to populate the in-memory `redis_store`, but did not mock `async_set_cache`. After the SET-NX seed change in `coalesced()`, the seed step writes via `async_set_cache(nx=True)` (default AsyncMock, no `redis_store` write), so the simulated Redis stays empty after the first reseed. The second `get_current_spend` then sees a clean Redis miss, re-enters the DB read path, and the test fails with `expected 1 DB query, got 2`. Fix: add a `redis_set_cache` side_effect that updates `redis_store` on `nx=True` (and rejects when the key already exists), matching the pattern used by the four sibling tests fixed in this branch's first commit. Pre-existing assertions are unchanged. Full `tests/test_litellm/proxy/test_proxy_server.py`: 158 passed.

This caused test_completion_mistral_api and test_completion_mistral_api_modified_input to fail in litellm.completion_cost lookup. - Add mistral/ministral-8b-2512 entry to both the in-tree model_prices_and_context_window.json and the bundled litellm/model_prices_and_context_window_backup.json (mirrors the existing openrouter/mistralai/ministral-8b-2512 pricing). - litellm.model_cost is loaded at import time from the URL pinned to main, so the new backup entry isn't visible at test runtime until it also lands on main.

The router was falling through to call the handler directly, bypassing _ageneric_api_call_with_fallbacks and leaving api_base=None for Azure deployments. Fall back to the model_id forwarded from the proxy ownership check so deployment credentials are always applied. Co-authored-by: Cursor <cursoragent@cursor.com> * fix(azure-containers): strip /openai/responses path from api_base in AzureContainerConfig.get_complete_url When a deployment's api_base is the responses endpoint URL (e.g. .../openai/responses?api-version=...), AzureContainerConfig was appending /openai/containers on top of it, producing the broken path .../openai/responses/openai/containers. Azure returns 404 for that URL while the correct path is .../openai/containers. Strip any /openai/responses suffix from api_base before constructing the containers URL so the resource root is always used as the starting point. Co-authored-by: Cursor <cursoragent@cursor.com> * fix(azure-containers): prefer api-version from api_base URL over deployment's api_version The deployment's api_version (e.g. 2024-08-01-preview) targets the chat/responses API and is too old for the containers API, which requires 2025-04-01-preview. The responses endpoint api_base already carries the correct api-version in its query string. Extract it and use it for the containers URL, overriding the stale deployment-level version. Fixes DELETE and file-upload operations returning 404 due to wrong api-version. Co-authored-by: Cursor <cursoragent@cursor.com> * fix(containers): pass params=None instead of params={} to httpx to preserve api-version httpx erases a URL's query-string when params={} (empty dict) is passed, silently stripping ?api-version=2025-04-01-preview from every container POST/DELETE request. Azure's GET endpoints tolerate a missing api-version; POST (upload) and DELETE are strict, so those returned 404. Fix: use `params or None` in container_handler._async_handle and llm_http_handler.async_container_delete_handler (and all sibling container handlers) so that an empty params dict falls back to None, leaving httpx to preserve the URL's existing query string intact. Adds a regression test that directly documents the httpx behaviour. Co-authored-by: Cursor <cursoragent@cursor.com> * fix(router): remove elif model_id branch from _init_containers_api_endpoints Two reviewer findings addressed: 1. Truncated comment on the model_id fallback line — now complete. 2. Security: the elif branch that fired when container_id was absent allowed any authenticated caller to supply model_id in a POST /v1/containers body and route the request through an arbitrary deployment UUID, bypassing the model-level access checks that only validate `model`. Removed the elif branch; operations without container_id (create, list) route by the caller-supplied `model` field as before. model_id forwarding is kept only inside the container_id block, where the proxy ownership check has already validated the container before forwarding the deployment ID. Adds a regression test pinning the security boundary: no-container-id path calls original_function directly even when model_id is in kwargs. Co-authored-by: Cursor <cursoragent@cursor.com> * test(containers): validate proxy-to-router model_id forwarding for managed IDs Add test_regression_get_container_forwarding_params_sets_model_id_for_managed_id to verify that get_container_forwarding_params (the proxy-side half of the Azure routing fix) correctly extracts and forwards model_id from a LiteLLM-managed encoded container ID. This closes the gap identified by Greptile P1: the previous regression test only injected model_id as a direct kwarg, validating the router in isolation. The new test exercises the actual proxy-to-router data flow through ownership.get_container_forwarding_params, confirming that kwargs["model_id"] is populated before _init_containers_api_endpoints is reached. Co-authored-by: Cursor <cursoragent@cursor.com> * fix(azure-containers): tighten endpoint-path strip to endswith match Use path.endswith() instead of path.find() for _AZURE_ENDPOINT_PATHS so the suffix strip only fires when api_base actually ends with one of the endpoint-specific path suffixes. This is the more precise check greptile flagged on the original find()-based implementation. * Fix sync container handler to preserve URL query string Mirror the async path fix: pass None instead of an empty params dict so httpx does not strip the URL's existing query string (e.g. ?api-version=...), which is required for Azure container routing.

For native upstream IDs (e.g. Azure 'cntr_<hex>') the decode fails and model_id was never forwarded — making the router-side fallback in _init_containers_api_endpoints unreachable in production. Fall back to the stored 'unified_object_id' on the ownership row, which is the encoded form captured at create time when the router selected a specific deployment. Decoding that yields the deployment model_id and restores router-based credential application (api_base, api_key) for retrieve/delete and container-file operations on native IDs.

Both selectors are gated to premium proxy admins, mirroring the server-side gate. Resolves LIT-3019 * fix(ui): persist team allowed_passthrough_routes edits on save The edit form loaded the selector but the save path never wrote it back: allowed_passthrough_routes stayed in the raw metadata JSON textarea and parsedMetadata (from that textarea) always won, so selector edits were silently discarded.

Resolves LIT-3019 * fix(ui): preserve team passthrough routes for non-proxy-admins on save Only proxy admins may set allowed_passthrough_routes (server-side gate). For non-proxy-admins, write the team's stored value back into metadata instead of the form value, so saving an unrelated setting can't silently wipe routes; omit the key entirely when the team never had any.

When the tool→server mapping is empty/stale (cold start, dynamic tools), the lookup would fail for alias-configured servers even though get_mcp_server_by_name (used by the REST path) matches alias, server_name, and name. Match the same priority of identifiers in both the registry pass and the unprefixed fallback so the MCP protocol call_tool path is consistent with the REST path.

Co-authored-by: Claude <claude@anthropic.com> * fix(mcp): retry tool-server lookup with prefixed name in REST mismatch check When the REST /mcp-rest/tools/call path sends a raw tool name plus requested_server_id, _get_mcp_server_from_tool_name(name) can return None if the mapping only stores the prefixed form. That bypassed the tool_server_mismatch 403 guard and let the call fall through to trusting requested_server. Retry the lookup with every known prefix of the requested server so the mismatch check fires whenever the tool is actually registered. Co-authored-by: Yassin Kortam <yassin@berri.ai> * fix(mcp): always reject unknown tools in server-name fallback Defense-in-depth: _resolve_mcp_server_for_tool_call previously skipped the unknown-tool check whenever the per-server mapping had no entries yet (cold start, OAuth2 lazy listing, or upstream listing failure), allowing arbitrary tool names to reach upstream servers. Tighten the check so the server-name fallback always rejects tool names not present in the mapping. Callers must call list_tools first (standard MCP flow) before tools/call can resolve. Removes the now-unused _mapping_has_tools_for_server helper and adds an explicit empty-mapping rejection test alongside the existing populated-mapping rejection test.

The first OutputTextDeltaEvent (and the second, when no ResponseCreatedEvent precedes the deltas) was consumed to emit a synthetic interaction.created / step.start event, but the chunk's text payload was never forwarded as a step.delta. The text only reappeared in the terminal step.stop, which defeats the purpose of incremental streaming. 2. When the upstream Responses API stream ended via StopIteration without a ResponseCompletedEvent, the iterator emitted step.stop but never the terminal interaction.completed event carrying the full collected text. This refactors the iterator to translate each upstream chunk into a list of events (instead of a single event) and buffers them in a deque. A text delta now expands into [interaction.created, step.start, step.delta] on the first chunk so no token is dropped, and the StopIteration / StopAsyncIteration fallback always flushes a terminal interaction.completed event when one hasn't already been sent. Both behaviors are covered by new unit tests: - test_no_text_token_is_dropped_during_streaming - test_response_created_then_text_delta_emits_step_start_and_delta - test_stop_iteration_fallback_emits_completion_event - test_response_completed_emits_stop_then_completion (no double-emit) Co-authored-by: Mateo Wang <mateo-berri@users.noreply.github.com> * fix(interactions): correlate EOF terminal events with stream's interaction id The StopIteration fallback path previously built the terminal step.stop / interaction.completed events with id=None (legacy content.stop) and a memory-address fallback string (interaction.completed), neither of which matched the item_id used by the earlier interaction.created / step.start / step.delta events in the same stream. Downstream consumers correlating events by id would see a mismatch. Persist the interaction id derived from the first upstream chunk (item_id on an OutputTextDeltaEvent, or response.id on a ResponseCreatedEvent) and reuse it when flushing the terminal events on EOF.

Try increasing UV_HTTP_TIMEOUT (current value: 30s). uv's default 30s per-request timeout is too tight for the Windows runner on this project (50+ deps, several multi-MB wheels), so bump it to 300s to let slow individual downloads complete instead of failing the build. * fix(interactions): correlate ResponseCompletedEvent terminal events with stream's interaction id When a stream starts directly with OutputTextDeltaEvent (no preceding ResponseCreatedEvent), interaction.created carries item_id while interaction.completed previously carried response.id from ResponseCompletedEvent. The two ids can differ, leaving consumers that correlate events by id unable to match the start and completion events. Fall back to self._interaction_id (set on the first chunk that derives an id) before response.id, mirroring the EOF terminal path. --------- Co-authored-by: Cursor Agent <cursoragent@cursor.com> Co-authored-by: Mateo Wang <mateo-berri@users.noreply.github.com> * fix(proxy): expose Prisma idle/connect timeout + extra DB URL params (#28395) * fix(proxy): expose Prisma idle/connect timeout + extra DB URL params Operators have reported large numbers of idle Prisma connections that never get closed.

But the Anthropic transformation here still guarded on isinstance(value, str), silently dropping the param. Result: callers using the standard Reasoning(effort, summary) OpenAI-shaped object on Anthropic lose thinking entirely (0 reasoning_tokens, no thinking_blocks). Coerce dict -> string before mapping. Same shape tolerance that gpt_5_transformation._normalize_reasoning_effort_for_chat_completion already implements. summary is irrelevant for Anthropic's thinking_blocks.

This caused test_completion_mistral_api and test_completion_mistral_api_modified_input to fail in litellm.completion_cost lookup. - Add mistral/ministral-8b-2512 entry to both the in-tree model_prices_and_context_window.json and the bundled litellm/model_prices_and_context_window_backup.json (mirrors the existing openrouter/mistralai/ministral-8b-2512 pricing). - litellm.model_cost is loaded at import time from the URL pinned to main, so the new backup entry isn't visible at test runtime until it also lands on main. Backfill any entries missing from the remote-fetched map into litellm.model_cost in the local_testing conftest so cost-calculator lookups succeed on this branch. * fix(tests): drop unnecessary del of conftest backfill loop vars * fix(router): harden streaming fallback wrapper for bridge iterators - FallbackResponsesStreamWrapper now uses getattr fallbacks when copying attributes from the source iterator. The bridge path (LiteLLMCompletionStreamingIterator used by Anthropic/Bedrock/Vertex) does not call super().__init__ and is missing response, logging_obj (it uses litellm_logging_obj), responses_api_provider_config, start_time, request_data, call_type, and _hidden_params. Previously, wrapper construction raised AttributeError for any streaming fallback on the bridge path. - _aresponses_with_streaming_fallbacks now deep-copies the litellm_metadata (and metadata) dicts into fallback_kwargs. The primary attempt mutates this dict in place via _update_kwargs_with_deployment, so a shallow copy of kwargs was leaking primary-deployment fields (deployment, model_info, api_base) into the mid-stream fallback request.

…oped JWT auth (#28356) * fix(proxy): point /metrics 401 at the opt-out flag Operators upgrading past 35bbca60b0 (which made /metrics auth default-on) see "Malformed API Key passed in. Ensure Key has 'Bearer ' prefix." with no hint that litellm_settings.require_auth_for_metrics_endpoint: false restores the previous unauthenticated behavior. Append that discovery hint to the existing 401 body so a Prometheus scraper that breaks after upgrade has a clear migration path. No behavior change. * fix(proxy): bound budget reservation per request instead of pinning to remaining headroom reserve_budget_for_request fell back to reserving the entire remaining team/key/user headroom whenever a request omitted max_tokens, which pinned the spend counter at max_budget for the duration of the in-flight request and false-positive-blocked every concurrent or back-to-back request until the success callback reconciled. Surfaced as an integration-test team being budget-blocked at its $2000 cap while DB spend was $0.144. Switch the missing-max_tokens path to a fixed default of 16384 output tokens (mirrors parallel_request_limiter_v3's DEFAULT_MAX_TOKENS_ESTIMATE precedent), and clamp explicit max_tokens at the model's max_output_tokens for reservation accounting only. The outbound request body is unchanged, so providers see whatever the caller actually sent; only the local integer used to compute reservation cost is bounded. This also prevents a hostile max_tokens=999999999 from inflating one request's reservation up to the entire team headroom. For Opus 4.7 (output $25/M, max_output 128K) on a $2000 budget the worst-case per-request reservation drops from "everything left" to $3.20, raising admittable concurrency from 1 to ~625. * fix(proxy): reserve per-image cost for image-generation requests Image-generation routes (dall-e-3, flux, etc.) have no per-token output cost so they fell through to the no-reservation read-time-only path. Concurrent image requests against a depleted budget could all pass common_checks (counter exactly at max_budget passes the strict-`>` gate) and reach the provider before reconciliation caught up. Add per-image reservation in _estimate_request_max_cost_for_model: when the model has a per-image cost field, reserve `n × cost_per_image` upfront. The atomic counter increment serializes concurrent admissions, so the second request sees the post-first-reservation counter and raises BudgetExceededError instead of silently leaking through. Both `output_cost_per_image` and `input_cost_per_image` are honored — naming is inconsistent across providers (OpenAI dall-e-3 uses input_cost_per_image, aiml/dall-e-3 uses output_cost_per_image for the same per-generated-image price). Per-pixel pricing (DALL-E 2 size variants) and TTS/STT routes still fall through to read-time enforcement; those are follow-ups. * fix(proxy): gate image-gen reservation strictly on model mode The previous detection treated any model with input_cost_per_image or output_cost_per_image as image generation. Several chat and embedding models carry those fields to price multimodal vision input, not generated images: - gemini-3.1-pro-preview (mode=chat) has output_cost_per_image=0.00012 alongside input/output token pricing. - azure/gpt-realtime-* (mode=chat) has input_cost_per_image=5e-6. - amazon.titan-embed-image-v1 (mode=embedding) has input_cost_per_image=6e-5. For these models the image-gen branch fired first and reserved a fraction of a cent per request, short-circuiting the token-priced path entirely. Long Gemini chats reserved 1 × $0.00012 instead of the true token cost. Gate strictly on mode in {"image_generation", "image_edit"}. All 197 real image_generation entries and all 31 image_edit entries (Flux Kontext, Stability inpaint/outpaint, etc.) carry the right mode, so the field-presence fallback was unnecessary. Adds regression tests for the chat-model-with-image-cost-field case and for image_edit reservation. * build(packaging): relax core runtime pins to ranges Backport of #27241 onto litellm_1.84.0rc2. The 12 entries in `[project.dependencies]` were exact `==` pins, a side effect of the Poetry -> uv migration. This forces every downstream package that lists litellm as a dependency to downgrade common runtime libraries (openai, pydantic, aiohttp, click, jsonschema, ...) to the exact versions we ship. Switch to lower-bounded ranges with upper bounds where the upstream package is pre-1.0 or has a known breaking-major-version policy. Reproducibility for our Docker proxy and CI continues to come from `uv.lock`, which is regenerated here as a metadata-only diff. Conflict resolution vs upstream merge: - The upstream merge commit also surfaced unrelated context entries (nvidia-riva-client, soundfile/stt-nvidia-riva extra) that exist in staging but not in rc2. Those are not part of #27241's intent and were dropped from the resolution; the rc2 uv.lock keeps its existing entry set, only the 12 specifier strings changed. - `uv lock --check` passes (392 packages resolved, no drift). * build(packaging): raise jinja2 floor to 3.1.6 Our `uv.lock` already resolves jinja2 to 3.1.6, so Docker / CI installs get that version. The `pyproject.toml` floor was lagging at 3.1.0, which means downstream consumers using `--resolution=lowest-direct` or older constraint files can land on 3.1.0-3.1.5 instead of the version we actually test against. Aligns the declared floor with the resolved version so external installers see the same baseline our test matrix exercises. `uv lock` diff is metadata-only (no resolved-version drift). * fix(mcp): forward extra_headers for OpenAPI MCP tools OpenAPI-generated tools only applied static closure headers and BYOK Authorization via ContextVar.

Restore the documented behavior: tags from the request always flow into `metadata.tags` and union with any admin-configured static tags from key/team/project metadata. Removes the `allow_client_tags` opt-in flag from the pre-call pipeline. The flag was only ever read here; it has no schema or endpoint footprint, so leftover values in existing key metadata are inert.

On the next request, _return_user_api_key_auth_obj resolved the rebound user_id against litellm_usertable and returned PROXY_ADMIN whenever the target row's user_role was admin. /key/update had the equivalent guard inline at _validate_update_key_data; extract it to a shared helper _validate_caller_can_change_key_ownership and call from both /key/update and _execute_virtual_key_regeneration. Also tighten the premium gate that allowed the master-key rotation branch to skip the enterprise check. The previous predicate was a field-presence test, not an identity check. Verify the caller actually holds the master key via _is_master_key before allowing the non-premium path. Block explicit-null user_id and empty-string user_id as removal attempts; both 403-reject for non-admin callers. * fix(proxy): expose db status on public /health/readiness Backport of #27866 onto litellm_1.84.0rc2. External readiness probes consumed the legacy detailed payload's `db` field to drive alerting and pod-rotation decisions. Stripping the body to {"status": "healthy"} broke those probes silently — the HTTP code still flipped to 503, but probes checking body.db == "connected" treated the response as healthy. Add `db` back to the unauthenticated payload. The rest of the diagnostic fields (litellm_version, callbacks, cache, log_level) stay behind /health/readiness/details so the recon-leak gate from #26912 holds. Values match the legacy contract: "connected", "disconnected", "Not connected". The 503-on-DB-disconnect behavior from LIT-2607 is preserved. * fix(ui): fetch version + debug flag from /health/readiness/details The proxy moved `litellm_version`, `is_detailed_debug`, and other diagnostic fields off the public `/health/readiness` payload behind an auth-gated `/health/readiness/details` endpoint. The navbar version tag and the detailed-debug-mode banner stopped working because they were still reading those fields from the unauthed response, which no longer contains them. Replace `useHealthReadiness` with a `useHealthReadinessDetails` hook that takes an `accessToken` argument and sends a Bearer header to the auth-gated endpoint. The hook stays disabled while `accessToken` is falsy, so the navbar can keep rendering on the public model hub (where the token is null) without triggering an auth redirect or a 401-loop. * fix(ui): disable retries on readiness/details + cover token forwarding Two small follow-ups on the readiness/details migration: - Set `retry: false` on the query. The payload feeds a passive navbar tag and a debug banner; a 401 from an expired token shouldn't fan out into three retries against the proxy. - Add navbar specs that assert the `accessToken` prop is forwarded into the hook (matches the DebugWarningBanner spec). Without this, the navbar could silently regress to passing `undefined` and the existing tests wouldn't catch it. * chore: update Next.js build artifacts (2026-05-14 03:52 UTC, node v20.20.2) * Merge pull request #27898 from stuxf/chore/banned-params-extra-body-cover chore(proxy): cover extra_body + azure_ad_token in banned-params check (cherry picked from commit a6a9d8edf024a7d808ba18df4aace4815e5f5925) * Merge pull request #27801 from stuxf/chore/get-instance-fn-runtime-s3-gate chore(proxy): refuse remote-URL instance-fn loads outside config-file path (cherry picked from commit e3e5209f51a605d49f4c1ef9b010ed5fdd1812c6) * fix: block client-side pricing injection via request body Authenticated clients could supply CustomPricingLiteLLMParams fields (input_cost_per_token, output_cost_per_token, etc.) in the request body. These were forwarded to register_model() in main.py, permanently mutating the shared global litellm.model_cost dict for all users on the instance. Adds all CustomPricingLiteLLMParams fields to _BANNED_REQUEST_BODY_PARAMS so is_request_body_safe() rejects them before they reach completion(). New pricing fields added to CustomPricingLiteLLMParams are auto-covered. Admin opt-in via allow_client_side_credentials or configurable_clientside_auth_params still works as before.

Any authenticated caller could redirect AssumeRole calls to an attacker-controlled server, leaking the proxy's instance profile credentials. Calls is_request_body_safe() on ingest_options["vector_store"] before forwarding to litellm.aingest().

A malformed Host like `localhost/?x=1` causes Starlette to build the full URL as `http://localhost/?x=1/health`, which url-parses to path="/". Since "/" is in LiteLLMRoutes.public_routes, all protected routes became reachable without authentication. Fix: read scope["path"] (set by uvicorn from the HTTP request line, not derivable from headers) instead of request.url.path. Sub-path deployments are handled via scope["app_root_path"] / scope["root_path"], mirroring Starlette's own base_url construction logic.

Credentials must be configured server-side. Previously any authenticated user could supply a vertex_credentials dict with type=external_account pointing credential_source.file at an arbitrary path (e.g. /proc/1/environ) and token_url at an attacker-controlled server. google-auth's identity_pool.Credentials refresh() would read the file and POST its contents to the attacker.

Gate: only the key creator (created_by == caller) may edit their own key without admin check; budget changes always require admin regardless of creator status.

Confirmed live: non-admin key could GET /credentials/by_name/openai (read masked provider API key) and DELETE /credentials/openai (delete credential).

Skip stripping when root_path is bare "/". migration: add IF NOT EXISTS to total_spend ALTER TABLE so the migration is safe to replay when a prior partial run already created the column. Without this guard, prisma migrate deploy fails on CI DBs that were partially migrated, causing all subsequent DB operations (including /team/new) to 500.

That broke transparent OAuth pass-through (EAI-506 V5/V6): standards- compliant MCP clients (OpenCode, Claude Code, mcp-inspector) complete PKCE against the upstream IdP and send the resulting token as plain Authorization: Bearer per the MCP spec — with the wider strip in place, that token never reaches the upstream and tools/list returns empty. Narrow the strip: skip Authorization for pass-through servers only when the caller did NOT supply x-litellm-api-key. When x-litellm-api-key is present, admission is unambiguous and Authorization is free to carry the upstream OAuth bearer. The original security guarantee is preserved — a client that sends only Authorization (no x-litellm-api-key) still has it stripped, so the LiteLLM key cannot leak upstream via that path. Tests: - new: forwards Authorization when x-litellm-api-key is present - new: still strips Authorization when only Authorization is present - existing pass-through + M2M tests unchanged Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * fix(interactions): align status enum with openapi spec * fix(mcp,jwt): address greptile review concerns - Cache _get_agent_object_permission via user_api_key_cache (sentinel for no-permission rows) so MCP requests from agent keys don't hit the DB on every tool-list / tool-call. - Re-raise HTTPException in handle_sse_mcp so 401 + WWW-Authenticate challenges (and other HTTP errors) propagate to SSE clients instead of being swallowed as 500. - Normalise booleans in _validate_token_response so admin rules written as JSON-style "true" / "false" match upstream responses that return Python True / False. - Treat configured JWT issuer claim mappings as advisory: when a mapped field is absent or empty, leave the normalised claim unset instead of raising, matching the global litellm_jwtauth path.

Switch to gpt-image-1, matching the existing TestOpenAIGPTImage1 pattern. (cherry picked from commit aee58db88057b274eab70388dce72eac31ea014f) * fix(tests): drop dall-e-only test classes; route live image tests via gpt-image-1 Second wave of failures from the 2026-05-12 DALL-E shutdown: - tests/image_gen_tests/test_image_edits.py::TestOpenAIImageEditDallE2 and tests/image_gen_tests/test_image_generation.py::TestOpenAIDalle3 are explicitly named for the deprecated models and can't pass; remove. gpt-image-1 coverage already exists in sibling classes. - tests/local_testing/test_router.py image gen tests use dall-e-3 only as a routing example; swap to gpt-image-1. - tests/local_testing/test_custom_callback_input.py image_generation success/failure paths swapped to gpt-image-1.

Swap the 6 references (3 files) to the currently-served accounts/fireworks/models/deepseek-v3p1 — the canonical model in Fireworks' current docs examples and present in LiteLLM's cost map. test_get_model_params_fireworks_ai is a pure pricing-heuristic test (no network) asserting the >16b branch, so it uses llama-v3p1-70b- instruct instead to keep the "fireworks-ai-above-16b" assertion and branch coverage intact. (cherry picked from commit 39a1d438f23f88d1c88f3e74930ab221b3e450de) * test(fireworks): mock remaining live smoke tests test_completion_fireworks_ai and test_completion_cost_fireworks_ai made real Fireworks calls and broke whenever Fireworks rotated its serverless catalog (no externally-verifiable model list exists). They also asserted nothing — just printed. Mock the HTTP post and assert real behavior instead: the request is built with the right model/messages and the OpenAI-compatible response parses back; the cost path yields a non-zero cost against the local cost map. No network, no model dependency, stronger than the old smoke checks.

The error was not "openai-internal", so the except block swallowed it and execution fell through to an unbound completion/response (UnboundLocalError). Switch both tests to gpt-audio-1.5, OpenAI's recommended successor (GA, not deprecated, already present in the litellm cost map so the response_cost assertion still resolves). Also broaden the except to skip with the real error in the reason instead of crashing, so a transient upstream blip can't reintroduce the UnboundLocalError. * fix(tests): narrow audio-test skip to model-not-found, re-raise the rest Address review feedback: an unconditional skip on any exception would silently mask a litellm-internal regression in the audio path (broken param transformation, serialization, bad header) instead of failing CI. Skip only on the upstream-unavailable class (model_not_found / "does not exist" / openai-internal) and re-raise everything else, so genuine regressions still fail loudly. The UnboundLocalError is still fixed because the handler either skips or raises - it never falls through. * fix(tests): add budget_exceeded to expected Interaction status enum Staging added budget_exceeded to the Interaction OpenAPI status enum; the staging merge into this branch picked up the spec change but not the matching test update, so test_status_enum_values failed in CI. Align the test's expected list (exact-match by design) with the live spec. * fix(tests): mock HTTP fetch in test_img_url_token_counter The test parameterized a live third-party image URL (blog.purpureus.net) which now 404s, causing get_image_dimensions to fall through to its base64 decode path and crash with 'not enough values to unpack' on every PR run. Mock safe_get with a tiny 1x1 PNG so the URL branch is still exercised without any network dependency. * fix(tests): swap gpt-4o-audio-preview to gpt-audio-1.5 in test_gpt4o_audio OpenAI shut down gpt-4o-audio-preview on 2026-05-07, so both live tests in test_gpt4o_audio.py (test_audio_output_from_model and test_audio_input_to_model) hard-fail model_not_found on every PR. Swap the hardcoded model to OpenAI's successor gpt-audio-1.5 (same chat-completions audio surface; already in the litellm cost map). Mirror the narrowed-skip pattern from the prior audio fixes: skip on model_not_found / does-not-exist / openai-internal, re-raise everything else so genuine litellm regressions still fail CI loudly. (cherry picked from commit 92de7423efca5756a2cb1bcf3228812628f91960) * fix(tests): migrate realtime + rerank tests off shut-down upstream models (#28191) * fix(tests): use gpt-realtime in realtime guardrails test OpenAI shut down gpt-4o-realtime-preview-2024-12-17 on 2026-05-07, so the live OpenAI realtime guardrails integration test now fails with model_not_found (session.created never arrives, _wait_for_event times out). Point OPENAI_REALTIME_URL at the current GA model, gpt-realtime. Scope limited to this test: the pricing-catalog JSON keeps the retired entries intentionally (historical cost calc + separate Azure timeline), and the Azure realtime cost-calc test is unaffected. * fix(tests): mock nvidia_nim rerank instead of hitting EOL'd endpoint NVIDIA reached end-of-life for the hosted nvidia/llama-3.2-nv-rerankqa-1b-v2 rerank API on 2026-05-18 with no published replacement, so the live BaseLLMRerankTest.test_basic_rerank for nvidia_nim now returns HTTP 410 ("Gone"). NVIDIA's hosted catalog rotates on a schedule, so swapping in another live model would only defer the failure. Override test_basic_rerank in TestNvidiaNim to mock the sync/async HTTP transport (same pattern as test_nvidia_nim_rerank_ranking_endpoint in this file) and inject a fake NVIDIA_NIM_API_KEY via monkeypatch. The request/response transformation and cost calculation stay covered offline. Scope limited to nvidia_nim; other BaseLLMRerankTest providers untouched. * fix(tests): migrate remaining realtime tests off shut-down gpt-4o-realtime-preview OpenAI's 2026-05-07 shutdown removed the entire gpt-4o-realtime-preview family, including the undated 'gpt-4o-realtime-preview' alias (not just the dated snapshot fixed earlier). Three live tests still connected with the dead alias and failed with messages_received=1 (an error event instead of session.created): - test_openai_realtime_simple.py: get_model() -> gpt-realtime (drives TestOpenAIRealtime.test_realtime_connection / test_realtime_with_query_params) - test_openai_realtime.py: test_openai_realtime_direct_call_no_intent and test_openai_realtime_direct_call_with_intent -> openai/gpt-realtime (the with_intent test shares the same dead alias even though it was not in the failing set this run) Mocked unit tests (test_realtime_query_params_construction, test_realtime_query_params_use_normalized_model_name) are left as-is: they never hit the network and assert string plumbing only. Also fixes test_text_message_blocked_by_guardrail_no_ai_response, which now connects (the earlier URL swap worked) but tripped a model-wording-brittle assertion. The guardrail flow asks the model to voice the block message verbatim; gpt-4o-realtime-preview complied (output contained 'blocked'), gpt-realtime refuses verbatim-repeat instructions ('I'm sorry, but I can't repeat that message.'). Since the original user message is blocked before it reaches OpenAI, the refusal is still a safe outcome. Assertion #3 now accepts both voicing and refusal, and adds a hard check that the blocked phrase never leaks into AI output.

Author: Claude <noreply@anthropic.com> * fix(mcp,auth): address greptile review concerns - handle_sse_mcp now calls _raise_preemptive_401_for_unauthenticated_servers so SSE clients to pass-through OAuth MCP servers receive the RFC 9728 401 + WWW-Authenticate challenge that the streamable-HTTP path already emits. - get_request_route strips a trailing slash from root_path before length-based prefix removal so non-canonical ASGI root_path values like "/litellm/" don't strip the leading slash from the returned route. - _mcp_oauth_user_api_key_auth's cookie JWT decode now passes options={"verify_aud": False} so a future revision of the UI session JWT containing an aud claim cannot silently downgrade the request to unauthenticated. Co-authored-by: Claude <claude@anthropic.com> * fix(tests): backfill local model_cost into remote-fetched map litellm.model_cost is loaded at import time from LITELLM_MODEL_COST_MAP_URL (pinned to main), so pricing entries that exist only in this branch (e.g. mistral/ministral-8b-2512, freshly added because Mistral's API now returns this id from mistral-tiny) are absent at test time and completion_cost lookups raise 'This model isn't mapped yet'. Backfill the in-tree backup into litellm.model_cost in the local_testing conftest so cassette-driven cost calculations resolve against the entries that ship with the branch under test. Fixes local_testing_part1 failures on test_completion_mistral_api and test_completion_mistral_api_modified_input. * fix(mcp,jwt): address greptile concurrency and code-quality concerns - _apply_issuer_claim_mappings now builds a new dict and reads from the original token, rather than mutating its input. The change is behaviour-preserving (caller passes a fresh jwt.decode result), but avoids the surprise-mutation pattern flagged by greptile. - is_network_error uses isinstance(exc, httpx.TransportError) instead of matching type(exc).__name__ against a hand-maintained string set, so ReadError / WriteError / ProxyError / etc. are also treated as transport-level failures and surfaced as HTTP 502. - fetch_upstream_oauth_protected_resource now coalesces concurrent discovery requests per (server_id, resource_url) through an asyncio.Lock so concurrent .well-known calls share a single upstream fetch + cache write. - Drop the redundant 'if trusted_ranges:' branch in get_mcp_client_ip; it is always true on the path that reaches it (the prior 'if not trusted_ranges:' early-returns). Co-authored-by: Claude <claude@anthropic.com> * fix(jwt,mcp): fall back to global JWKS on unknown issuer; prune fetch locks - handle_jwt._get_configured_issuer now returns None for tokens whose 'iss' is not in the configured issuers list, letting auth_jwt fall through to the legacy JWT_PUBLIC_KEY_URL path instead of hard-raising. This keeps existing tokens from non-configured IdPs working when an operator adds the new 'issuers' list to a live deployment. - discoverable_endpoints._prune_oauth_metadata_cache now also prunes entries in _OAUTH_METADATA_FETCH_LOCKS whose cache entry has been evicted and whose lock isn't currently held, bounding the locks dict to match the cache it guards. Co-authored-by: Claude <claude@anthropic.com> * fix(mcp,auth): restore client_ip in oauth2 target check, drop from delegate check The merge of staging into the PR branch (d42a66adb6) misplaced the client_ip=client_ip kwarg: it landed inside _target_servers_delegate_auth_to_upstream (which never accepted client_ip and isn't called with it), while the sibling _target_servers_use_oauth2 has client_ip in its signature but stopped passing it through to get_mcp_server_by_name. That left ruff flagging F821 on the undefined name and lint failing. Move client_ip back into _target_servers_use_oauth2's lookup (matching the call site that already forwards IPAddressUtils.get_mcp_client_ip) and drop it from _target_servers_delegate_auth_to_upstream so its body matches its signature again. * fix(mcp): respect client ip for delegated auth * fix(auth): address remaining greptile style findings - get_request_route: require root_path to match whole path segments before stripping, so '/apifoo' isn't truncated to 'foo' when root_path='/api'. - get_mcp_client_ip: collapse the two trusted-proxy validation branches into a single is_request_from_trusted_proxy call so the return value drives control flow instead of being discarded for the side-effect warning. Co-authored-by: Claude <claude@anthropic.com> * fix(jwt): strip internal _litellm_* claims in global JWKS auth path Prevents identity spoofing where a token signed by the global JWKS could inject _litellm_jwt_issuer and other _litellm_* claims that downstream getters trust. The issuer-scoped path already strips these via _apply_issuer_claim_mappings; mirror that behavior for the global fallback path. Co-authored-by: Yassin Kortam <yassin@berri.ai> * fix(mcp): surface MCPUpstreamAuthError as 401 in SSE/HTTP transport handlers Both handle_sse_mcp and handle_streamable_http_mcp only caught HTTPException to preserve 401 + WWW-Authenticate challenges, but MCPUpstreamAuthError (raised when a pass-through server's upstream rejects a bearer token mid-session) inherits from Exception. It was falling through to the generic handler and surfacing as an opaque 500. Mirror the REST endpoint behavior: translate MCPUpstreamAuthError into an HTTPException(status_code=e.status_code) with the upstream www-authenticate header so standards-compliant MCP clients trigger the upstream OAuth flow. Co-authored-by: Yassin Kortam <yassin@berri.ai> * fix(mcp): add upstream auth pre-flight in SSE handler Mirror handle_streamable_http_mcp by calling _check_passthrough_upstream_auth after the cold-start 401 emitter so expired/invalid upstream tokens surface a proper 401 + WWW-Authenticate challenge before the SSE session commits 200 headers, instead of letting list_tools silently return [] when the upstream rejects the token. Co-authored-by: Claude <noreply@anthropic.com> * fix(mcp): tighten cold-start bypass against CSV paths + dedupe upstream auth probe - Return None from _parse_mcp_server_names_from_path for CSV multi-server paths (/mcp/a,b). The regex previously truncated at the first comma and silently passed a single server name to the cold-start gate. - Switch _is_mcp_passthrough_cold_start to all-targets semantics, matching _target_servers_use_oauth2: one non-passthrough target in a co-targeted set must not flip the anonymous-admission bypass open for the others. - Drop the redundant HTTPStatusError block in _extract_upstream_auth_failure - any HTTPStatusError carries a .response, so the preceding generic block already handles 401/403 detection. Co-authored-by: Yassin Kortam <yassin@berri.ai> * fix(mcp,tests): sync stubs and cold-start assertions with delegate-check The merge of base-branch _target_servers_delegate_auth_to_upstream into process_mcp_request inserts an additional get_mcp_server_by_name(name) lookup ahead of the cold-start path, which breaks two test patterns: 1. lookup_by_name(name) side-effect stubs in TestMCPDelegateAuthToUpstream are called positionally by the delegate check, then again by the cold-start path with client_ip=... — raising TypeError: unexpected keyword argument 'client_ip'. Accept **_kwargs to match the real signature. 2. TestMCPPassthroughColdStartAdmission assertions count the lookup exactly once with client_ip=..., but the delegate check now adds a positional-only call ahead of it. Switch assert_called_once_with to assert_any_call for the cold-start invocation, and assert client_ip was *not* passed for the aggregate /mcp test where cold-start must not fire. Both updates align with CLAUDE.md guidance to keep monkeypatch stubs in sync with the real signature when an optional parameter is added. Co-authored-by: Claude <claude@anthropic.com> * fix(mcp): correct passthrough probe 401 + slashed-name cold start parser - _check_passthrough_upstream_auth now emits 'Bearer resource_metadata="..."' pointing at the gateway's oauth-protected-resource well-known URL, mirroring the pre-emptive 401 path. Pass-through servers don't use the gateway as an authorization server, so the previous 'authorization_uri=' challenge sent clients to the wrong metadata endpoint. - _parse_mcp_server_names_from_path now accepts server names that contain a single slash (e.g. custom_solutions/user_123), mirroring MCPRequestHandler._extract_target_server_names_from_path. Without this, the cold-start bypass missed slashed-name servers and the generic admission error propagated instead of the spec-compliant 401 challenge. - _is_mcp_passthrough_cold_start drops the unused scope parameter from its signature. Co-authored-by: Yassin Kortam <yassin@berri.ai> * style(mcp): format discoverable endpoints * refactor(mcp): dedupe MCPUpstreamAuthError->HTTPException + thread client_ip into delegate-auth gate Co-authored-by: Yassin Kortam <yassin@berri.ai> * fix(mcp): handle passthrough OAuth metadata and startup auth errors - discoverable_endpoints: For pass-through MCP servers, when upstream oauth-protected-resource returns a non-200/non-dict response, raise HTTP 502 instead of falling through to default gateway metadata. Falling through would direct MCP clients at the gateway, which is not the authorization server for pass-through configs. - mcp_server_manager: Wrap _get_tools_from_server in startup tool name mapping with try/except. Since _get_tools_from_server now re-raises MCPUpstreamAuthError, an upstream 401 from a pass-through server at startup (when no user token is present) would otherwise abort the loop and leave subsequent servers unmapped. Co-authored-by: Yassin Kortam <yassin@berri.ai> * fix(mcp): restrict passthrough probe challenge to OAuth passthrough servers The probe filter previously matched any server with Authorization in extra_headers, including gateway-managed OAuth2 servers. Those would then receive the resource_metadata= WWW-Authenticate challenge meant for pass-through servers, instead of the authorization_uri= challenge pointing at the gateway AS metadata. Use srv.is_oauth_passthrough so only genuine pass-through servers get the resource-metadata challenge. Co-authored-by: Yassin Kortam <yassin@berri.ai> * test(proxy): cover issuer-scoped JWT auth * fix(mcp): use resource metadata for passthrough reauth * fix(mcp,tests): assert cold-start helper directly for aggregate /mcp Threading client_ip into _target_servers_delegate_auth_to_upstream made get_mcp_server_by_name(name, client_ip=...) also fire from the delegate-auth check, so the call_args_list assertion on client_ip-in-kwargs no longer uniquely signals a cold-start lookup. Patch _is_mcp_passthrough_cold_start and assert it is not invoked, which is the actual contract the test is pinning. * fix(mcp,jwt): drop unneeded async helper + suppress misleading unscoped JWT warning - _build_oauth_authorization_server_response: revert to sync (no awaits in body). The function only does dict construction and synchronous registry lookups; async added coroutine creation overhead per discovery call without need. - _build_decode_kwargs: accept has_issuer_config so the global path's 'JWT auth is unscoped' warning is suppressed when LiteLLM_JWTAuth.issuers provides per-issuer scoping. Previously the warning fired spuriously for admins who intentionally use only the new issuers config. * fix(jwt,mcp): clarify issuers fallthrough + add TTL on mcp permission cache - LiteLLM_JWTAuth.issuers docs now state explicitly that unlisted issuers fall back to the global JWT_AUDIENCE/JWT_ISSUER path; the field is additive routing, not an allow-list. Matches actual control flow in handle_jwt.auth_jwt and the regression tests asserting backwards compatibility with the global JWKS path. - MCPRequestHandler._get_{org,agent}_object_permission now pass ttl=DEFAULT_MANAGEMENT_OBJECT_IN_MEMORY_CACHE_TTL on async_set_cache, mirroring the auth_checks.py pattern so the cache TTL is explicit on both DualCache layers. * fix(tests): align merged JWT and MCP cold-start assertions Update the tests carried over from PR #28008 to match the assertions on the staging branch: - tests/test_litellm/proxy/auth/test_handle_jwt.py: unknown issuers now fall back to the legacy JWT_PUBLIC_KEY_URL path (per litellm_feat/v1.84.0-mcp-gateway-jwt-auth's '\''fall back to global JWKS on unknown issuer'\''), and mapped issuer claims that are absent no longer fail closed — they simply leave the normalised LiteLLM internal claim absent. - tests/test_litellm/proxy/_experimental/mcp_server/auth/test_user_api_key_auth_mcp.py: the aggregate '\''/mcp'\'' route still triggers the delegate-auth-to-upstream lookup once for the header-supplied server name; cold-start admission must NOT fire on top of that. Tighten the assertion to assert_called_once_with so a future regression that re-enters cold-start is caught. Co-authored-by: Mateo Wang <mateo-berri@users.noreply.github.com> * fix(jwt): guard litellm_jwtauth access in auth_jwt global path JWTHandler() can be constructed without update_environment() being called (tests do this directly), in which case self.litellm_jwtauth does not exist. Accessing it raises AttributeError before getattr can fall back. Use the same safe pattern other call sites use. * Gate MCP OAuth pass-through on delegate_auth_to_upstream flag Sameer's review on #28356/#28008 flagged that the new pass-through behaviors (preemptive 401 challenges, /.well-known/oauth-protected- resource proxying, upstream 401/403 propagation as MCPUpstreamAuthError, and Authorization-stripping when no x-litellm-api-key is supplied) were implicitly enabled for every server with auth_type=none plus Authorization in extra_headers. Existing users doing static bearer pass-through for non-OAuth reasons would have silently regressed. Make the detection rule explicit: extend the existing delegate_auth_to_upstream flag (previously oauth2-only) to also gate is_oauth_passthrough. Now requires flag + auth_type=None + Authorization in extra_headers, per Sameer's suggested detection rule. The UI toggle now appears for both modes (oauth2 PKCE passthrough and auth_type=none OAuth pass-through) with mode-appropriate copy. Update test fixtures to set the flag where the test intent is to exercise OAuth pass-through behavior, and add negative tests covering the new default-false case. * fix(mcp): route org object_permission lookup through shared auth helpers Replace the bespoke litellm_organizationtable.find_unique + dedicated cache key in _get_org_object_permission with get_org_object + get_object_permission so MCP requests share the same user_api_key_cache entries as the rest of the proxy and no longer fragment org-row caching. * fix(mcp): wrap get_object_permission call in shared try/except Ensure exceptions from get_object_permission in _get_org_object_permission are caught and return None, preserving the original fail-safe semantics. Co-authored-by: Yassin Kortam <yassin@berri.ai> * fix(jwt): validate issuer audience at config load + dedicated key-miss exception - Move JWTIssuerConfig audience-required guard into a Pydantic model_validator so misconfiguration fails at startup instead of on the first request. - Replace the string-match `No matching public key found` filter in get_public_key's multi-URL fallback with a dedicated NoMatchingJWTPublicKeyError; only that specific exception triggers continuation, every other error still surfaces. * fix(mcp): admit and forward Authorization for passthrough OAuth return For pass-through MCP servers (auth_type=none with delegate_auth_to_upstream) the RFC 9728 cold-start flow sends the client back with only "Authorization: Bearer <upstream-token>" after upstream OAuth discovery. Previously this path 1) was rejected in process_mcp_request because the oauth2_headers fallback only covered auth_type=oauth2 targets, and 2) had the Authorization header stripped by _prepare_mcp_server_headers when no x-litellm-api-key was present, treating the upstream token as a potential LiteLLM key leak. - Extend the elif oauth2_headers fallback to also admit anonymously when every target is a pass-through server. - Pass user_api_key_auth into _prepare_mcp_server_headers so it can forward Authorization for pass-through servers when admission did not consume the bearer as a LiteLLM key (api_key is unset). Co-authored-by: Yassin Kortam <yassin@berri.ai> * fix(mcp): consistent www-authenticate casing + SSE toolset scoping - Normalize the WWW-Authenticate header key emitted by _check_passthrough_upstream_auth to lowercase to match the other 401 emitters in the OAuth pass-through flow. - Mirror the streamable HTTP handler's toolset scoping in handle_sse_mcp: strip client-supplied x-mcp-toolset-id and apply _apply_toolset_scope before _check_passthrough_upstream_auth so the upstream probe list is derived from the fully-authorized server set. - Tighten _has_client_supplied_mcp_auth signature so mcp_server_auth_headers is Optional, matching its caller in process_mcp_request. Co-authored-by: Yassin Kortam <yassin@berri.ai> * security(mcp): strip Authorization in call_tool when LiteLLM admission used legacy header Mirror the OAuth pass-through admission check from _prepare_mcp_server_headers (list-tools path) in _call_regular_mcp_tool (tool-call path): when the server is OAuth pass-through and the caller did not supply x-litellm-api-key, Authorization on the inbound request may itself be the LiteLLM API key — so strip it before forwarding instead of leaking the gateway credential upstream. When x-litellm-api-key is present, admission is unambiguous and Authorization continues to carry the upstream OAuth bearer (transparent pass-through). * refactor(mcp): centralize caller Authorization strip decision Extracted the security-sensitive logic that decides whether the caller's Authorization header is forwarded to (or stripped from) an outgoing MCP request into a single helper, _should_strip_caller_authorization, in mcp_server_manager.py. Previously the same condition was duplicated across _call_regular_mcp_tool (mcp_server_manager.py) and _prepare_mcp_server_headers (server.py). Keeping two copies of this check risked future divergence and credential-leak / broken-passthrough bugs. Both call sites now share the helper, preserving exact behavior. Co-authored-by: Yassin Kortam <yassin@berri.ai> * log MCP OAuth discovery diagnostics for unmatched paths and non-transport upstream errors * fix(jwt): include issuer-normalized team id in get_all_jwt_team_ids The aggregator for team IDs only consulted the issuer-normalized claim for the plural (team_ids) path and fell back to the global config for the singular path. When an operator configures team_id_jwt_field only at the issuer level, get_team_id correctly returned the mapped value but get_all_jwt_team_ids silently dropped it, causing membership reconciliation to disagree with request routing. Co-authored-by: Yassin Kortam <yassin@berri.ai> * fix(mcp/jwt): dedupe cold-start path parser; reject conflicting audience flags - _parse_mcp_server_names_from_path now delegates to MCPRequestHandler._extract_target_server_names_from_path so the names used by the cold-start passthrough bypass cannot drift from the names used by downstream routing. - JWTIssuerConfig now rejects the combination of audience and disable_audience_validation=True at validation time instead of silently ignoring the flag. * fix(mcp): restrict passthrough cold-start bypass to 401 only The new elif passthrough cold-start branch reused is_auth_error which matches both 401 and 403. A 403 from user_api_key_auth indicates the LiteLLM key WAS recognized but is forbidden (e.g. over budget / rate limited); falling through to anonymous UserAPIKeyAuth() in that case bypasses spend and rate-limit controls on passthrough servers. Only trigger the cold-start anonymous admission on 401, which is the signal that the bearer is an upstream OAuth token rather than a recognized LiteLLM key. Co-authored-by: Yassin Kortam <yassin@berri.ai> * fix(jwt/mcp): warn on unscoped JWT fallback; route agent permission lookup through shared helper - _build_decode_kwargs no longer suppresses the unscoped-fallback warning when LiteLLM_JWTAuth.issuers is set: tokens whose iss does not match any configured issuer still fall through to the global path, and that fallback is itself unscoped when JWT_AUDIENCE/JWT_ISSUER are absent. - _get_agent_object_permission now caches the agent_id -> object_permission_id mapping and delegates the permission lookup to the shared get_object_permission helper, so the agent path reuses the same cache entries as the org / team / key paths. * fix(mcp): fabricate resource_metadata challenge when upstream 401 omits WWW-Authenticate When an upstream pass-through MCP server returns 401 without a WWW-Authenticate header (non-compliant per RFC 7235 §3.1), to_http_exception() now produces a synthetic Bearer challenge pointing at the gateway's standard-pattern oauth-protected-resource well-known endpoint for that server. This keeps MCP clients on the RFC 9728 discovery flow instead of receiving a bare 401 with no recovery hint. * fix(jwt): make _get_decode_options explicitly control verify_iss Previously, _get_decode_options only set verify_aud based on whether audience was provided. The issuer JWT path relied on always passing issuer=issuer_config.issuer to trigger PyJWT's default verify_iss=True, making the helper's behavior implicitly dependent on caller behavior. Now _get_decode_options accepts issuer as well, mirroring the verify_aud handling and matching the dimensions handled by _build_decode_kwargs. Co-authored-by: Yassin Kortam <yassin@berri.ai> * fix(mcp): emit absolute resource_metadata URI in fabricated 401 challenge Per RFC 9728 §3.2 the resource_metadata Bearer challenge must be an absolute URI; strict MCP clients reject relative URIs and fail to initiate discovery. MCPUpstreamAuthError.to_http_exception now accepts the gateway base URL and prepends it when the upstream omitted WWW-Authenticate, and all four call sites (streamable HTTP, SSE, and the two REST tool-list paths) supply it. * fix(mcp): correct 403 detail text and remove dead _list_tools_for_single_server duplicate - MCPUpstreamAuthError.to_http_exception() now returns detail='Forbidden' for 403 upstream responses (and 'Unauthorized' for 401), matching the _check_passthrough_upstream_auth pre-flight probe. - Remove the shadowed first definition of _list_tools_for_single_server in rest_endpoints.py; the second definition was the live one and the dead copy was a maintenance trap. Co-authored-by: Yassin Kortam <yassin@berri.ai> * fix: address potential bugs in auth_utils, mcp discoverable endpoints, and mcp auth - auth_utils.get_request_route: return '/' instead of empty string when raw_path exactly equals root_path so downstream route allowlist checks still see a leading slash - discoverable_endpoints.fetch_upstream_oauth_protected_resource: also cache negative results (no upstream metadata) for a shorter TTL so we don't re-fetch on every discovery request and so the per-key fetch lock can be pruned - user_api_key_auth_mcp: guard the oauth2_headers 401 cold-start passthrough bypass with _has_client_supplied_mcp_auth, matching the parallel bypass in the no-Authorization branch so MCP-auth-bearing requests don't silently downgrade to anonymous admission Co-authored-by: Yassin Kortam <yassin@berri.ai> * test(vertex): tolerate transient InternalServerError in google maps tool test test_gemini_google_maps_tool_simple makes live calls to Vertex AI's Google Maps grounding backend, which intermittently returns 500 INTERNAL ("Please retry") — a transient upstream failure, not a LiteLLM bug. The test already passes on RateLimitError; treat InternalServerError the same way so transient Vertex-side failures don't fail CI. * refactor(mcp): drop redundant has_client_credentials filter on passthrough probe is_oauth_passthrough already requires auth_type in (None, MCPAuth.none), which is mutually exclusive with has_client_credentials (auth_type == MCPAuth.oauth2), so the extra guard was always True and only added confusion about whether a server could be both passthrough and M2M. Co-authored-by: Yassin Kortam <yassin@berri.ai> * fix: restore unreachable InternalServerError skip handler in vertex test Co-authored-by: Yassin Kortam <yassin@berri.ai> * feat(mcp): add dedicated oauth_passthrough flag for non-oauth2 pass-through Previously is_oauth_passthrough reused delegate_auth_to_upstream — a flag scoped to oauth2 servers (PKCE bypass) — to gate OAuth pass-through for auth_type=none servers. Overloading it risked regressing existing deployments that set delegate_auth_to_upstream, since the same flag would silently start driving pass-through (discovery proxying, 401 challenges, upstream 401/403 propagation) on non-oauth2 servers. Introduce a separate oauth_passthrough opt-in so the two behaviors never imply each other: - MCPServer.is_oauth_passthrough now requires oauth_passthrough (not delegate_auth_to_upstream). - Persist oauth_passthrough on LiteLLM_MCPServerTable (new column + migration) and wire it through config/DB load and API responses. - UI splits the single toggle into two: "Delegate auth to upstream (PKCE passthrough)" for oauth2 and "OAuth pass-through" for auth_type=none servers forwarding Authorization. Adds backend tests (property, round-trip, and a regression guard that delegate_auth_to_upstream alone never enables pass-through) and UI tests for the toggle split. * fix(mcp): reconcile cold-start bypass with x-mcp-servers header and skip non-absolute WWW-Authenticate fabrication - _parse_mcp_server_names_from_path now fails closed when the x-mcp-servers header introduces any target not present in the path-derived target set, closing a header/path mismatch where the cold-start passthrough bypass could otherwise admit anonymously while the header advertises a non-passthrough server. - MCPUpstreamAuthError.to_http_exception no longer emits a relative resource_metadata URI when base_url is missing; per RFC 9728 3.2 the URI must be absolute, so we skip fabrication entirely rather than send a challenge strict MCP clients will reject. Co-authored-by: Yassin Kortam <yassin@berri.ai> * fix(mcp): fabricate path-aware resource_metadata URI for upstream 401 When MCPUpstreamAuthError.to_http_exception fabricates a `WWW-Authenticate: Bearer resource_metadata=...` challenge (because the upstream 401 omitted one), the URL now matches the inbound MCP transport pattern the client originally used: - /mcp/{server_name} -> /.well-known/oauth-protected-resource/mcp/{server_name} - /{server_name}/mcp -> /.well-known/oauth-protected-resource/{server_name}/mcp This mirrors the path-aware behaviour of _get_passthrough_resource_metadata_url in server.py so strict RFC 9728 \xA73.2 clients on legacy routes get a resource_metadata URI aligned with the resource pattern they originally targeted. Co-authored-by: Yassin Kortam <yassin@berri.ai> * fix(jwt+mcp): tighten issuer-scoped claim type handling, RFC-quote authorization_uri, surface MCP upstream auth errors, defense-in-depth on decode options - handle_jwt: when an issuer-scoped _litellm_team_ids claim exists but has an unexpected type, return [] instead of falling through to the global team_ids_jwt_field path (different claim semantically). - handle_jwt: _get_decode_options/_decode_jwt_with_public_key now take an explicit disable_audience_validation flag; passing audience=None without it raises, so audience checks can't silently disappear if the model validator is ever bypassed. _auth_jwt_with_issuer forwards the flag from JWTIssuerConfig. - mcp_server: quote the authorization_uri WWW-Authenticate parameter value (RFC 6750 / 9728 auth-param must be quoted-string), matching the pass-through path. - mcp_server: in _fetch_and_filter_server_tools, re-raise MCPUpstreamAuthError so the outer streamable-HTTP handler can surface a proper 401 + WWW-Authenticate challenge instead of returning an empty tool list.

…BerriAI#28281) * fix(tests): replace shut-down gpt-4o-audio-preview with gpt-audio-1.5 OpenAI shut down gpt-4o-audio-preview on 2026-05-07, so the live audio calls in test_stream_chunk_builder_openai_audio_output_usage and test_standard_logging_payload_audio now hard-fail with a model-not-found error on every PR. The error was not "openai-internal", so the except block swallowed it and execution fell through to an unbound completion/response (UnboundLocalError). Switch both tests to gpt-audio-1.5, OpenAI's recommended successor (GA, not deprecated, already present in the litellm cost map so the response_cost assertion still resolves). Also broaden the except to skip with the real error in the reason instead of crashing, so a transient upstream blip can't reintroduce the UnboundLocalError. * fix(tests): narrow audio-test skip to model-not-found, re-raise the rest Address review feedback: an unconditional skip on any exception would silently mask a litellm-internal regression in the audio path (broken param transformation, serialization, bad header) instead of failing CI. Skip only on the upstream-unavailable class (model_not_found / "does not exist" / openai-internal) and re-raise everything else, so genuine regressions still fail loudly. The UnboundLocalError is still fixed because the handler either skips or raises - it never falls through. * fix(tests): add budget_exceeded to expected Interaction status enum Staging added budget_exceeded to the Interaction OpenAPI status enum; the staging merge into this branch picked up the spec change but not the matching test update, so test_status_enum_values failed in CI. Align the test's expected list (exact-match by design) with the live spec. * fix(tests): mock HTTP fetch in test_img_url_token_counter The test parameterized a live third-party image URL (blog.purpureus.net) which now 404s, causing get_image_dimensions to fall through to its base64 decode path and crash with 'not enough values to unpack' on every PR run. Mock safe_get with a tiny 1x1 PNG so the URL branch is still exercised without any network dependency. * fix(tests): swap gpt-4o-audio-preview to gpt-audio-1.5 in test_gpt4o_audio OpenAI shut down gpt-4o-audio-preview on 2026-05-07, so both live tests in test_gpt4o_audio.py (test_audio_output_from_model and test_audio_input_to_model) hard-fail model_not_found on every PR. Swap the hardcoded model to OpenAI's successor gpt-audio-1.5 (same chat-completions audio surface; already in the litellm cost map). Mirror the narrowed-skip pattern from the prior audio fixes: skip on model_not_found / does-not-exist / openai-internal, re-raise everything else so genuine litellm regressions still fail CI loudly.

* fix(llm_http_handler): forward kwargs['model_info'] to litellm_params for /v1/messages Router._update_kwargs_with_deployment stamps the selected deployment's model_info on kwargs['model_info'] before dispatching the request. Downstream cooldown / success callbacks (deployment_callback_on_failure, deployment_callback_on_success) look up the deployment id via kwargs['litellm_params']['model_info']['id']. async_anthropic_messages_handler constructs its own litellm_params dict when calling logging_obj.update_from_kwargs and never forwarded model_info. As a result, /v1/messages requests dispatched through the Router had an empty model_info on litellm_params, the deployment id was not discoverable, and cooldown / success tracking were silently skipped for this call type. Forward kwargs['model_info'] into the litellm_params dict so the existing Router callbacks can identify the deployment. * merge main (#29486) * [Refactor] UI - Spend Logs: consolidate filter state and extract components (#25847) * [Refactor] UI - Spend Logs: consolidate filter state, extract components, remove dead code - Lift filter state into index.tsx and pass to hook (removes selectedX vars + sync useEffect) - Move main useQuery into useLogFilterLogic hook (removes isMainQueryEnabled toggle) - Delete dead RequestViewer component (300 lines, replaced by LogDetailsDrawer) - Extract LogsTableToolbar component (search, date range, pagination, live tail) - Extract filter options config to filter_options.ts - Remove dead code: handleRefresh, handleSelectLog, handleCloseDrawer, formatTimeUnit, showFilters/showColumnDropdown state, dropdownRef/filtersRef * Fix PR feedback: use antd Switch instead of Tremor in new file, fix typo * Collapse dual-path filtering into single React Query All 10 filter keys now go through the useQuery — the imperative performSearch / debouncedSearch / backendFilteredLogs path is deleted. Filter values are debounced via useDebouncedValue(300ms) before hitting the query key so text inputs don't fire per-keystroke. Removed: performSearch, debouncedSearch, backendFilteredLogs, lastSearchTimestamp, hasBackendFilters, clientDerivedFilteredLogs, the sort/page/time refetch useEffect, and the filteredLogs chooser memo. * Clean up remaining smells: remove isFetchingDeferred, internalize selectedTimeInterval, fix circular import - Remove useDeferredValue/isButtonLoading — pass logsQuery.isFetching directly - Move selectedTimeInterval into LogsTableToolbar as internal state - Move PaginatedResponse type from index.tsx to log_filter_logic.tsx * Fix quick-select dropdown overlapping sidebar * Fix stale quick-select label after Reset Filters Move selectedTimeInterval back to parent so handleFilterReset can reset it to the 24-hour default. The toolbar receives it as a prop. * refactor useLogFilterLogic tests for controlled-hook + backend-query shape The hook no longer owns filter state or does client-side filtering — it receives filters/setFilters as props and drives filteredLogs from a useQuery over uiSpendLogsCall. Reshape the tests around that contract: introduce a controlled harness that owns filter state, collapse the 10 per-filter assertions into a single it.each over filterKey → API param, and drop the client-side passthrough tests (the .min test file and the "return all logs when no filters" / "empty when logs null" cases) that no longer correspond to any hook behavior. * cover new useLogFilterLogic invariants: activeTab gate, filterByCurrentUser fallback, debounce negative, partial merge Follow-up to the test refactor. Adds coverage for invariants the refactored hook contract introduced but that the first pass didn't assert: - query enablement: expand the single accessToken-null case into an it.each over all four credential props (accessToken, token, userRole, userID), plus a separate test for activeTab !== "request logs" - filterByCurrentUser: when true with a blank User ID filter, the outbound request carries user_id = userID - debounce: also assert the negative case — no call in the first 100ms after a filter change (first waiting out the initial mount fire) - handleFilterChange: partial updates merge without clobbering other filter keys (protects the spread + default-fill semantics) - handleFilterReset: calls setCurrentPage(1) alongside restoring filters * fix typo dropping the live-tail banner border Tailwind silently ignores unknown classes, so border-greem-200 was leaving the auto-refresh banner with only its bg-green-50 fill and no outline. * memoize columns and derived table data in SpendLogsTable The table's columns array, four-pass data pipeline, and sort-change handler were all being rebuilt on every parent render. That made every filter click re-instance all 23 TanStack-Table columns, re-run filter/reduce/map over all rows, and recreate per-row click closures — all before the intentional 300ms debounce timer even got a chance to fire. Local measurement (40 rows, dev mode): filter click → query fires: 1957ms → 1217ms (−38%) Wrap createColumns in useMemo keyed on sortBy/sortOrder, hoist onSortChange into a useCallback, and move the searchedLogs / sessionComposition / sessionRepresentativeMap / filteredData derivations into a single useMemo keyed on filteredLogs.data + searchTerm. These were pre-existing issues on main — not regressions from the hook refactor — but the refactor made them user-visible because the new query debounce put render cost on the critical path. * apply dropdown filters instantly, debounce only text inputs Dropdown selects now bypass the 300ms debounce so a click updates the table immediately. Text inputs (Key Hash, Error Message, Request ID, User ID) still debounce. handleFilterReset also clears the pending debounced value so a half-typed text filter can't re-fire after reset. * fix(ui/spend-logs): restore lost loading/debounce behavior + cover dropped tests Regressions from the spend-logs-view refactor: - debounce the 'Public model / search tool' text filter (was firing a backend query per keystroke) via TEXT_FILTER_KEYS - restore Fetch-button smoothing through table repaint using useDeferredValue on the rendered data (explicit staleness) - show AntDLoadingSpinner during the auth-resolve phase instead of a blank screen on first load - only live-tail-poll while the tab is visible (refetchIntervalInBackground: false) - extract getLiveTailRefetchInterval helper for the poll decision Tests: - LogDetailContent: retries display (>0 / 0 / absent), overhead-absent - log_filter_logic: regression guard that the public-model filter debounces; getLiveTailRefetchInterval unit tests - logs_utils: getTimeRangeDisplay quick-select window labels * test(ui/spend-logs): cover the cold-load auth-not-ready spinner guard Asserts SpendLogsTable shows a loading spinner (not a blank screen) while credentials are unresolved, and renders the table once present. * fix(tests): replace shut-down gpt-4o-audio-preview with gpt-audio-1.5 (#28281) * fix(tests): replace shut-down gpt-4o-audio-preview with gpt-audio-1.5 OpenAI shut down gpt-4o-audio-preview on 2026-05-07, so the live audio calls in test_stream_chunk_builder_openai_audio_output_usage and test_standard_logging_payload_audio now hard-fail with a model-not-found error on every PR.

Co-authored-by: Sameer Kankute <Sameerlite@users.noreply.github.com> * fix: forward query-param credentials to list/get/delete/versions Gemini agent endpoints The list_gemini_agents, get_gemini_agent, delete_gemini_agent, and list_gemini_agent_versions endpoints previously constructed a hardcoded data dict with no mechanism to pass provider credentials. Unlike create_gemini_agent (POST, reads litellm_params_template from body), these GET/DELETE endpoints gave no way for multi-tenant callers to supply a per-request api_key or other LiteLLM params. Fix: - Add _merge_query_params_into_data() helper that reads query parameters from the request and merges them into the data dict without overwriting already-set keys (e.g. path params like 'name'). - Support a JSON-encoded litellm_params_template query parameter (matching the POST body pattern) as well as flat key=value pairs (e.g. api_key=AIza...). - Apply the helper in all four affected endpoints. - Add 13 unit tests covering the helper and each endpoint. Co-authored-by: Sameer Kankute <Sameerlite@users.noreply.github.com> * fix: pass model=None for managed agent proxy endpoints to prevent agent name polluting data["model"] Endpoints acreate_agent, aget_agent, adelete_agent, and alist_agent_versions were passing model=<agent_name> to base_process_llm_request. This caused common_processing_pre_call_logic to write the agent name into self.data["model"], which then triggered spurious model-alias mapping, rate-limiting lookups, and logging tied to a non-existent model deployment. The agent name is already carried in data["name"] and is passed correctly to the SDK functions (litellm.interactions.agents.*). There is no reason to also set model=<agent_name>; the correct value is model=None for all five managed-agent management routes. Adds tests/test_litellm/proxy/google_endpoints/test_managed_agents_model_param.py to verify all five managed-agent endpoints pass model=None. Co-authored-by: Sameer Kankute <Sameerlite@users.noreply.github.com> * fix: address greptile P1/P2 review comments P1 (router.py): Restore fallback/retry support for acreate_interaction and create_interaction. Both were silently moved to _init_interactions_api_endpoints (direct call, no fallbacks). Moved them back to _ageneric_api_call_with_fallbacks so users with configured fallback models keep retry behaviour. P1 security (agents_endpoints.py): Remove flat query-param credential path (e.g. ?api_key=AIza...) from _merge_query_params_into_data. Credentials in URL query strings appear verbatim in server access logs, CDN edge logs, and browser history. Only the JSON-encoded litellm_params_template query param (matching the POST body pattern) is retained. P2 (interactions/http_handler.py): Extract _BaseHTTPHandler with shared _handle_error, _sync_client, and _async_client helpers. InteractionsHTTPHandler now extends _BaseHTTPHandler. The _async_client reads the provider from litellm_params instead of hardcoding GEMINI. P2 (interactions/agents/http_handler.py): AgentsHTTPHandler now extends InteractionsHTTPHandler (which inherits _BaseHTTPHandler) so all shared HTTP infrastructure is reused rather than duplicated. Removes the hardcoded LlmProviders.GEMINI from the async client path. Co-authored-by: Cursor <cursoragent@cursor.com> * fix: address CI failures from greptile review fixes - black: format interactions/agents/main.py and utils.py - tests: update test_gemini_agents_endpoints.py to match new _merge_query_params_into_data behaviour (flat credential params are rejected; only JSON-encoded litellm_params_template is accepted) - ci: add test_gemini_agents_endpoints.py to endpoints-and-responses shard in test-unit-proxy-db.yml so assert-shard-coverage passes - tests: add _initialize_managed_agents_endpoints and _init_managed_agents_api_endpoints test coverage so router_code_coverage passes; also fix TestRouterCreateInteractionRouting to reflect that acreate_interaction now correctly routes through _ageneric_api_call_with_fallbacks (restoring fallback support) Co-authored-by: Cursor <cursoragent@cursor.com> * fix: remove InteractionsHTTPHandler._handle_error override to fix type errors AgentsHTTPHandler extends InteractionsHTTPHandler and calls self._handle_error(provider_config=agents_api_config) where agents_api_config is BaseAgentsAPIConfig. Python MRO resolved _handle_error to InteractionsHTTPHandler._handle_error which expected BaseInteractionsAPIConfig, causing 10 mypy arg-type errors in interactions/agents/http_handler.py. Removing the redundant override lets both classes inherit _BaseHTTPHandler._handle_error (provider_config: Any) which is structurally correct for both config types. Co-authored-by: Cursor <cursoragent@cursor.com> * fix: agent-only interactions and managed agents provider routing Resolve None custom_llm_provider in agents HTTP client lookup and set custom_llm_provider on GenericLiteLLMParams for all agent CRUD paths. Stop mapping agent names to proxy model routing; route interactions through _init_interactions_api_endpoints with fallbacks only when model is set. Consolidate duplicate router elif branches for interaction APIs. Co-authored-by: Cursor <cursoragent@cursor.com> * Fix greptile review * test(agents): add unit tests for managed agents SDK and HTTP handler Adds coverage for the new `litellm.interactions.agents` surface area: - main.py: sync/async entry points (create/list/get/delete/list_versions), provider config lookup, logging-obj helper, async error wrapping - http_handler.py: every CRUD method (sync + async paths), `_is_async` dispatch branches, and provider error mapping through GeminiAgentsConfig - utils.py: get_provider_agents_api_config for supported / unsupported providers Brings patch coverage on these files from <25% to ~100% so codecov/patch is satisfied. Co-authored-by: Mateo Wang <mateo-berri@users.noreply.github.com> * docs(gemini-agents): fix misleading credential-passing examples in GET/DELETE docstrings (#28293) The four GET/DELETE endpoint docstrings (list_gemini_agents, get_gemini_agent, delete_gemini_agent, list_gemini_agent_versions) documented passing per-request credentials as flat query parameters (e.g. ?api_key=AIza...). However, _merge_query_params_into_data only reads the JSON-encoded litellm_params_template query parameter and intentionally ignores flat params (URL query strings appear verbatim in access logs, browser history, and Referer headers). Callers following the documented curl examples would have their credentials silently dropped and hit auth failures against Gemini. Update the examples to use the supported JSON-encoded litellm_params_template query parameter, matching _merge_query_params_into_data's own docstring. Co-authored-by: Cursor Agent <cursoragent@cursor.com> Co-authored-by: Mateo Wang <mateo-berri@users.noreply.github.com> * refactor(agents): rename provider-agnostic agent response types Move GeminiAgent{ListResponse,DeleteResult,VersionsResponse} to provider-neutral names (AgentListResponse, AgentDeleteResult, AgentVersionsResponse) so the BaseAgentsAPIConfig interface no longer references Gemini-specific type names. * fix(gemini-agents): close veria-flagged credential-escalation gaps Two high-severity findings from the veria-ai PR review are addressed: 1. **api_base override could leak the shared Gemini key** GeminiAgentsConfig.validate_environment falls back to GOOGLE_API_KEY / GEMINI_API_KEY when no api_key is supplied. Combined with caller-controlled api_base on the proxy CRUD endpoints, an authenticated user could redirect the outbound request to an attacker-controlled host and capture the operator's shared Gemini key from the x-goog-api-key header. The config now refuses env-fallback whenever api_base is explicitly overridden. 2. **Managed-agent CRUD exposed to ordinary LLM keys** The new /v1beta/agents routes live in google_routes (i.e. llm_api_routes), so any non-admin LLM key can reach them. Unlike /v1beta/models/...: generateContent these endpoints are NOT model-routed and have no model_list-supplied credentials, so env-fallback would let any LLM key list / create / delete agents inside the operator's Gemini project. Each endpoint now calls _enforce_caller_supplied_provider_key, which requires non-admin callers to supply their own Gemini api_key via litellm_params_template. Proxy admins keep the env-fallback convenience. Tests cover non-admin rejection, admin allow-through, the api_base override guard, and SDK env-fallback when api_base is not overridden.

Root cause ---------- `SpendCounterReseed.coalesced` warmed the primary spend counter by calling `redis.async_increment(key, value=db_spend, refresh_ttl=True)`, which lowers to Redis `INCRBYFLOAT`. That is additive, not idempotent. The per-counter `asyncio.Lock` only coalesces seeders inside one process. With N pods sharing one Redis, on a cold key (cold start, TTL expiry, manual delete) every pod independently passes its lock + Redis re-check, reads the same `db_spend`, and issues `INCRBYFLOAT db_spend`. Final value: N x db_spend. Fix --- Use `redis.async_set_cache(key, value=db_spend, nx=True)` for the seed. SET NX is atomic across pods: exactly one writer initializes the key; losers read the winner's value via `async_get_cache`. This is the same idiom already used by `coalesced_window` in the same file, so the two seed paths are now consistent. Per-request deltas continue to use `INCRBYFLOAT` (correct - additive behaviour is what we want for increments, not for initial seed). Verification ------------ Live two-process repro against the same Postgres + Redis (DB spend = 506): Unpatched: 4/4 runs -> Redis counter = ~1012 (~2 x db_spend) Patched: 12/12 runs -> Redis counter = ~506 Unit tests (`test_proxy_server.py`): - New `test_primary_spend_counter_redis_concurrent_seed_does_not_double_seed` patches `_get_lock` to return a fresh lock per caller (otherwise the per-process lock masks the race), races two `coalesced` calls, and asserts final = 506 with exactly one of two SET NX attempts winning. - 4 existing tests updated for the new seed contract (SET NX for the seed, INCRBYFLOAT only for the per-request delta). - Full `spend_counter or reseed or budget` slice: 22 passed. Co-authored-by: Cursor <cursoragent@cursor.com> * test(spend_counter): make SET NX mock atomic so loser branch is exercised Greptile flagged that `redis_set_cache` in test_primary_spend_counter_redis_concurrent_seed_does_not_double_seed placed `await asyncio.sleep(0)` AFTER the NX membership check. Both concurrent tasks observed an empty `redis_store`, passed the guard, and both returned True - so the loser branch (else: read back winner's value) was never exercised. Fix the mock to model real atomic Redis SET NX: - Yield BEFORE the membership check so two concurrent callers interleave the way real SET NX does (first to resume runs check + write atomically and wins; second resumes after the key exists and loses). - Track set_cache return values; assert sorted([loser, winner]) so we know exactly one task wins and one loses. - Track async_get_cache calls that happen AFTER at least one SET NX has completed; assert at least one such read - that is the loser-path fallback (`current_value = float(cached)` when seeded is False). Verified by temporarily reverting the mock to the old order: the test now fails with `expected exactly one SET NX winner and one loser, got [True, True]`, exactly the failure mode Greptile described. No production code change. Co-authored-by: Cursor <cursoragent@cursor.com> * test(spend_counter): mock async_set_cache to populate redis_store in concurrent read+write test `test_concurrent_read_and_write_paths_share_one_db_query` mocks `async_increment` to populate the in-memory `redis_store`, but did not mock `async_set_cache`. After the SET-NX seed change in `coalesced()`, the seed step writes via `async_set_cache(nx=True)` (default AsyncMock, no `redis_store` write), so the simulated Redis stays empty after the first reseed. The second `get_current_spend` then sees a clean Redis miss, re-enters the DB read path, and the test fails with `expected 1 DB query, got 2`. Fix: add a `redis_set_cache` side_effect that updates `redis_store` on `nx=True` (and rejects when the key already exists), matching the pattern used by the four sibling tests fixed in this branch's first commit. Pre-existing assertions are unchanged. Full `tests/test_litellm/proxy/test_proxy_server.py`: 158 passed.

This caused test_completion_mistral_api and test_completion_mistral_api_modified_input to fail in litellm.completion_cost lookup. - Add mistral/ministral-8b-2512 entry to both the in-tree model_prices_and_context_window.json and the bundled litellm/model_prices_and_context_window_backup.json (mirrors the existing openrouter/mistralai/ministral-8b-2512 pricing). - litellm.model_cost is loaded at import time from the URL pinned to main, so the new backup entry isn't visible at test runtime until it also lands on main.

The router was falling through to call the handler directly, bypassing _ageneric_api_call_with_fallbacks and leaving api_base=None for Azure deployments. Fall back to the model_id forwarded from the proxy ownership check so deployment credentials are always applied. Co-authored-by: Cursor <cursoragent@cursor.com> * fix(azure-containers): strip /openai/responses path from api_base in AzureContainerConfig.get_complete_url When a deployment's api_base is the responses endpoint URL (e.g. .../openai/responses?api-version=...), AzureContainerConfig was appending /openai/containers on top of it, producing the broken path .../openai/responses/openai/containers. Azure returns 404 for that URL while the correct path is .../openai/containers. Strip any /openai/responses suffix from api_base before constructing the containers URL so the resource root is always used as the starting point. Co-authored-by: Cursor <cursoragent@cursor.com> * fix(azure-containers): prefer api-version from api_base URL over deployment's api_version The deployment's api_version (e.g. 2024-08-01-preview) targets the chat/responses API and is too old for the containers API, which requires 2025-04-01-preview. The responses endpoint api_base already carries the correct api-version in its query string. Extract it and use it for the containers URL, overriding the stale deployment-level version. Fixes DELETE and file-upload operations returning 404 due to wrong api-version. Co-authored-by: Cursor <cursoragent@cursor.com> * fix(containers): pass params=None instead of params={} to httpx to preserve api-version httpx erases a URL's query-string when params={} (empty dict) is passed, silently stripping ?api-version=2025-04-01-preview from every container POST/DELETE request. Azure's GET endpoints tolerate a missing api-version; POST (upload) and DELETE are strict, so those returned 404. Fix: use `params or None` in container_handler._async_handle and llm_http_handler.async_container_delete_handler (and all sibling container handlers) so that an empty params dict falls back to None, leaving httpx to preserve the URL's existing query string intact. Adds a regression test that directly documents the httpx behaviour. Co-authored-by: Cursor <cursoragent@cursor.com> * fix(router): remove elif model_id branch from _init_containers_api_endpoints Two reviewer findings addressed: 1. Truncated comment on the model_id fallback line — now complete. 2. Security: the elif branch that fired when container_id was absent allowed any authenticated caller to supply model_id in a POST /v1/containers body and route the request through an arbitrary deployment UUID, bypassing the model-level access checks that only validate `model`. Removed the elif branch; operations without container_id (create, list) route by the caller-supplied `model` field as before. model_id forwarding is kept only inside the container_id block, where the proxy ownership check has already validated the container before forwarding the deployment ID. Adds a regression test pinning the security boundary: no-container-id path calls original_function directly even when model_id is in kwargs. Co-authored-by: Cursor <cursoragent@cursor.com> * test(containers): validate proxy-to-router model_id forwarding for managed IDs Add test_regression_get_container_forwarding_params_sets_model_id_for_managed_id to verify that get_container_forwarding_params (the proxy-side half of the Azure routing fix) correctly extracts and forwards model_id from a LiteLLM-managed encoded container ID. This closes the gap identified by Greptile P1: the previous regression test only injected model_id as a direct kwarg, validating the router in isolation. The new test exercises the actual proxy-to-router data flow through ownership.get_container_forwarding_params, confirming that kwargs["model_id"] is populated before _init_containers_api_endpoints is reached. Co-authored-by: Cursor <cursoragent@cursor.com> * fix(azure-containers): tighten endpoint-path strip to endswith match Use path.endswith() instead of path.find() for _AZURE_ENDPOINT_PATHS so the suffix strip only fires when api_base actually ends with one of the endpoint-specific path suffixes. This is the more precise check greptile flagged on the original find()-based implementation. * Fix sync container handler to preserve URL query string Mirror the async path fix: pass None instead of an empty params dict so httpx does not strip the URL's existing query string (e.g. ?api-version=...), which is required for Azure container routing. Co-authored-by: Yassin Kortam <yassin@berri.ai> * fix(azure-containers): strip trailing slash before endpoint suffix match Co-authored-by: Yassin Kortam <yassin@berri.ai> * fix(containers): recover model_id from stored encoded id for native Azure container IDs get_container_forwarding_params previously only set model_id when the user-supplied container_id was a LiteLLM-managed encoded id. For native upstream IDs (e.g. Azure 'cntr_<hex>') the decode fails and model_id was never forwarded — making the router-side fallback in _init_containers_api_endpoints unreachable in production. Fall back to the stored 'unified_object_id' on the ownership row, which is the encoded form captured at create time when the router selected a specific deployment. Decoding that yields the deployment model_id and restores router-based credential application (api_base, api_key) for retrieve/delete and container-file operations on native IDs.

The previous custom isFilteringResults flag was removed in the #25847 toolbar refactor and only partially restored on the Fetch button. Use React Query's isPlaceholderData to discriminate a real filter change (queryKey changed, data not yet arrived) from a same-key live-tail refetch, and feed it into the existing isLoading prop on the toolbar pagination text and the table body. Live-tail polls still keep previous rows without flicker.

Adds a Playwright test for creating an admin key with no team selected (all-proxy-models flow), a SLOWMO env hook for headed debugging, and a MIGRATION_TRACKING.md doc that maps the manual UI QA checklist to e2e tests so future migration work has a single source of truth. * chore(e2e): address greptile feedback - Remove MIGRATION_TRACKING.md (docs belong in litellm-docs repo) - playwright.config.ts: fall back to 0 when SLOWMO is non-numeric (parseInt returns NaN, which Playwright accepts silently) - run_e2e.sh: add --frozen to uv sync for CI determinism * feat(ui): team passthrough routes create parity + edit load fix (#28098) * feat(ui): team allowed_passthrough_routes create parity + edit load fix Add the Allowed Pass Through Routes selector to the create-team modal (previously only on the edit form), and fix the edit form silently dropping the field: it lives under team metadata, so initialValues must read info.metadata.allowed_passthrough_routes — otherwise the selector renders empty and saving wipes admin-set routes. Both selectors are gated to premium proxy admins, mirroring the server-side gate. Resolves LIT-3019 * fix(ui): persist team allowed_passthrough_routes edits on save The edit form loaded the selector but the save path never wrote it back: allowed_passthrough_routes stayed in the raw metadata JSON textarea and parsedMetadata (from that textarea) always won, so selector edits were silently discarded. Strip it from the textarea initialValues and overlay values.allowed_passthrough_routes into updateData.metadata, mirroring how guardrails is handled. Resolves LIT-3019 * fix(ui): preserve team passthrough routes for non-proxy-admins on save Only proxy admins may set allowed_passthrough_routes (server-side gate). For non-proxy-admins, write the team's stored value back into metadata instead of the form value, so saving an unrelated setting can't silently wipe routes; omit the key entirely when the team never had any. Resolves LIT-3019 * fix(mcp): JWT on tools/list and REST tools/call server resolution (#28227) * fix(mcp): JWT on tools/list, REST server_id resolution, tool_server_mismatch Sign outbound MCP JWTs for list_mcp_tools and inject headers on the tools/list path.

Co-authored-by: Cursor <cursoragent@cursor.com> * fix(mcp): restrict list JWTs to mcp:tools/list and default REST arguments to {} - List-only JWTs (call_type=list_mcp_tools) no longer carry the broad mcp:tools/call scope. _build_scope() now emits only mcp:tools/list when no tool name is provided, mirroring the existing least-privilege rule that tool-call JWTs omit mcp:tools/list. - REST /tools/call now defaults a missing 'arguments' field to {} so execute_mcp_tool() and downstream **arguments / .keys() calls don't receive None and crash with TypeError/AttributeError.

When the tool→server mapping is empty/stale (cold start, dynamic tools), the lookup would fail for alias-configured servers even though get_mcp_server_by_name (used by the REST path) matches alias, server_name, and name. Match the same priority of identifiers in both the registry pass and the unprefixed fallback so the MCP protocol call_tool path is consistent with the REST path. Co-authored-by: Yassin Kortam <yassin@berri.ai> * fix(mcp): reuse proxy_logging DualCache in inject_mcp_jwt_headers_for_upstream Instead of allocating a fresh DualCache() on every tools/list invocation, prefer the shared proxy_logging_obj.internal_usage_cache.dual_cache when available. The cache argument is currently unused by MCPJWTSigner, but sharing the proxy's cache avoids per-call allocation overhead and matches the cache identity used elsewhere in the proxy hook plumbing — so any future per-request state stored in cache will survive across list calls. * fix(mcp): return 403 ip_filtering for IP-restricted servers in tools/call name lookup Co-authored-by: Yassin Kortam <yassin@berri.ai> * fix(test): accept user_api_key_auth kwarg in list_tools mocks The proxy-infra job was failing on four TestMCPServerManager tests because the mock_get_tools_from_server stubs did not accept the new user_api_key_auth keyword argument that list_tools now forwards to _get_tools_from_server. Add the kwarg to each stub so list_tools can call through cleanly. * fix(mcp): skip JWT injection when per-user mcp_auth_header is set MCPClient._get_auth_headers() applies extra_headers AFTER writing Authorization from auth_value, so an injected JWT silently overwrites the user's per-server OAuth token. Guard the JWT signer with 'not mcp_auth_header' so per-user OAuth (and any dict-form per-user auth) takes precedence, mirroring the existing static_headers guard. Adds a regression test that the signer's inject helper is not called when mcp_auth_header is supplied. * fix(mcp): skip JWT injection when extra_headers already has Authorization When a server uses per-user OAuth tokens, the resolved token is passed into _get_tools_from_server via extra_headers. The JWT injection guard only checked mcp_auth_header and the server's static headers, so the signer would silently overwrite the user's OAuth Authorization header. Add a check for an existing Authorization entry in extra_headers so caller-supplied per-user OAuth tokens take precedence over JWT signing. Co-authored-by: Yassin Kortam <yassin@berri.ai> * test(mcp): cover JWT signer + tool-call resolution branches Adds unit tests for the new MCPServerManager helpers (_resolve_mcp_server_for_tool_call, _resolve_oauth2_headers_for_tool_call) and the new MCPJWTSigner paths (_build_scope call_type branches and inject_mcp_jwt_headers_for_upstream). Brings patch coverage above the auto target without changing behavior. * fix(mcp): retry tool-server lookup with prefixed name in REST mismatch check When the REST /mcp-rest/tools/call path sends a raw tool name plus requested_server_id, _get_mcp_server_from_tool_name(name) can return None if the mapping only stores the prefixed form. That bypassed the tool_server_mismatch 403 guard and let the call fall through to trusting requested_server. Retry the lookup with every known prefix of the requested server so the mismatch check fires whenever the tool is actually registered. Co-authored-by: Yassin Kortam <yassin@berri.ai> * fix(mcp): always reject unknown tools in server-name fallback Defense-in-depth: _resolve_mcp_server_for_tool_call previously skipped the unknown-tool check whenever the per-server mapping had no entries yet (cold start, OAuth2 lazy listing, or upstream listing failure), allowing arbitrary tool names to reach upstream servers. Tighten the check so the server-name fallback always rejects tool names not present in the mapping. Callers must call list_tools first (standard MCP flow) before tools/call can resolve. Removes the now-unused _mapping_has_tools_for_server helper and adds an explicit empty-mapping rejection test alongside the existing populated-mapping rejection test.

The first OutputTextDeltaEvent (and the second, when no ResponseCreatedEvent precedes the deltas) was consumed to emit a synthetic interaction.created / step.start event, but the chunk's text payload was never forwarded as a step.delta. The text only reappeared in the terminal step.stop, which defeats the purpose of incremental streaming. 2. When the upstream Responses API stream ended via StopIteration without a ResponseCompletedEvent, the iterator emitted step.stop but never the terminal interaction.completed event carrying the full collected text. This refactors the iterator to translate each upstream chunk into a list of events (instead of a single event) and buffers them in a deque. A text delta now expands into [interaction.created, step.start, step.delta] on the first chunk so no token is dropped, and the StopIteration / StopAsyncIteration fallback always flushes a terminal interaction.completed event when one hasn't already been sent. Both behaviors are covered by new unit tests: - test_no_text_token_is_dropped_during_streaming - test_response_created_then_text_delta_emits_step_start_and_delta - test_stop_iteration_fallback_emits_completion_event - test_response_completed_emits_stop_then_completion (no double-emit) Co-authored-by: Mateo Wang <mateo-berri@users.noreply.github.com> * fix(interactions): correlate EOF terminal events with stream's interaction id The StopIteration fallback path previously built the terminal step.stop / interaction.completed events with id=None (legacy content.stop) and a memory-address fallback string (interaction.completed), neither of which matched the item_id used by the earlier interaction.created / step.start / step.delta events in the same stream. Downstream consumers correlating events by id would see a mismatch. Persist the interaction id derived from the first upstream chunk (item_id on an OutputTextDeltaEvent, or response.id on a ResponseCreatedEvent) and reuse it when flushing the terminal events on EOF.

Try increasing UV_HTTP_TIMEOUT (current value: 30s). uv's default 30s per-request timeout is too tight for the Windows runner on this project (50+ deps, several multi-MB wheels), so bump it to 300s to let slow individual downloads complete instead of failing the build. * fix(interactions): correlate ResponseCompletedEvent terminal events with stream's interaction id When a stream starts directly with OutputTextDeltaEvent (no preceding ResponseCreatedEvent), interaction.created carries item_id while interaction.completed previously carried response.id from ResponseCompletedEvent. The two ids can differ, leaving consumers that correlate events by id unable to match the start and completion events. Fall back to self._interaction_id (set on the first chunk that derives an id) before response.id, mirroring the EOF terminal path. --------- Co-authored-by: Cursor Agent <cursoragent@cursor.com> Co-authored-by: Mateo Wang <mateo-berri@users.noreply.github.com> * fix(proxy): expose Prisma idle/connect timeout + extra DB URL params (#28395) * fix(proxy): expose Prisma idle/connect timeout + extra DB URL params Operators have reported large numbers of idle Prisma connections that never get closed.

But the Anthropic transformation here still guarded on isinstance(value, str), silently dropping the param. Result: callers using the standard Reasoning(effort, summary) OpenAI-shaped object on Anthropic lose thinking entirely (0 reasoning_tokens, no thinking_blocks). Coerce dict -> string before mapping. Same shape tolerance that gpt_5_transformation._normalize_reasoning_effort_for_chat_completion already implements. summary is irrelevant for Anthropic's thinking_blocks.

The bridge path (LiteLLMCompletionStreamingIterator used by Anthropic/Bedrock/Vertex) does not call super().__init__ and is missing response, logging_obj (it uses litellm_logging_obj), responses_api_provider_config, start_time, request_data, call_type, and _hidden_params. Previously, wrapper construction raised AttributeError for any streaming fallback on the bridge path. - _aresponses_with_streaming_fallbacks now deep-copies the litellm_metadata (and metadata) dicts into fallback_kwargs. The primary attempt mutates this dict in place via _update_kwargs_with_deployment, so a shallow copy of kwargs was leaking primary-deployment fields (deployment, model_info, api_base) into the mid-stream fallback request.

…suer-scoped JWT auth (BerriAI#28356) * fix(proxy): point /metrics 401 at the opt-out flag Operators upgrading past 35bbca60b0 (which made /metrics auth default-on) see "Malformed API Key passed in. Ensure Key has 'Bearer ' prefix." with no hint that litellm_settings.require_auth_for_metrics_endpoint: false restores the previous unauthenticated behavior. Append that discovery hint to the existing 401 body so a Prometheus scraper that breaks after upgrade has a clear migration path. No behavior change. * fix(proxy): bound budget reservation per request instead of pinning to remaining headroom reserve_budget_for_request fell back to reserving the entire remaining team/key/user headroom whenever a request omitted max_tokens, which pinned the spend counter at max_budget for the duration of the in-flight request and false-positive-blocked every concurrent or back-to-back request until the success callback reconciled. Surfaced as an integration-test team being budget-blocked at its $2000 cap while DB spend was $0.144. Switch the missing-max_tokens path to a fixed default of 16384 output tokens (mirrors parallel_request_limiter_v3's DEFAULT_MAX_TOKENS_ESTIMATE precedent), and clamp explicit max_tokens at the model's max_output_tokens for reservation accounting only. The outbound request body is unchanged, so providers see whatever the caller actually sent; only the local integer used to compute reservation cost is bounded. This also prevents a hostile max_tokens=999999999 from inflating one request's reservation up to the entire team headroom. For Opus 4.7 (output $25/M, max_output 128K) on a $2000 budget the worst-case per-request reservation drops from "everything left" to $3.20, raising admittable concurrency from 1 to ~625. * fix(proxy): reserve per-image cost for image-generation requests Image-generation routes (dall-e-3, flux, etc.) have no per-token output cost so they fell through to the no-reservation read-time-only path. Concurrent image requests against a depleted budget could all pass common_checks (counter exactly at max_budget passes the strict-`>` gate) and reach the provider before reconciliation caught up. Add per-image reservation in _estimate_request_max_cost_for_model: when the model has a per-image cost field, reserve `n × cost_per_image` upfront. The atomic counter increment serializes concurrent admissions, so the second request sees the post-first-reservation counter and raises BudgetExceededError instead of silently leaking through. Both `output_cost_per_image` and `input_cost_per_image` are honored — naming is inconsistent across providers (OpenAI dall-e-3 uses input_cost_per_image, aiml/dall-e-3 uses output_cost_per_image for the same per-generated-image price). Per-pixel pricing (DALL-E 2 size variants) and TTS/STT routes still fall through to read-time enforcement; those are follow-ups. * fix(proxy): gate image-gen reservation strictly on model mode The previous detection treated any model with input_cost_per_image or output_cost_per_image as image generation. Several chat and embedding models carry those fields to price multimodal vision input, not generated images: - gemini-3.1-pro-preview (mode=chat) has output_cost_per_image=0.00012 alongside input/output token pricing. - azure/gpt-realtime-* (mode=chat) has input_cost_per_image=5e-6. - amazon.titan-embed-image-v1 (mode=embedding) has input_cost_per_image=6e-5. For these models the image-gen branch fired first and reserved a fraction of a cent per request, short-circuiting the token-priced path entirely. Long Gemini chats reserved 1 × $0.00012 instead of the true token cost. Gate strictly on mode in {"image_generation", "image_edit"}. All 197 real image_generation entries and all 31 image_edit entries (Flux Kontext, Stability inpaint/outpaint, etc.) carry the right mode, so the field-presence fallback was unnecessary. Adds regression tests for the chat-model-with-image-cost-field case and for image_edit reservation. * build(packaging): relax core runtime pins to ranges Backport of #27241 onto litellm_1.84.0rc2. The 12 entries in `[project.dependencies]` were exact `==` pins, a side effect of the Poetry -> uv migration. This forces every downstream package that lists litellm as a dependency to downgrade common runtime libraries (openai, pydantic, aiohttp, click, jsonschema, ...) to the exact versions we ship. Switch to lower-bounded ranges with upper bounds where the upstream package is pre-1.0 or has a known breaking-major-version policy. Reproducibility for our Docker proxy and CI continues to come from `uv.lock`, which is regenerated here as a metadata-only diff. Conflict resolution vs upstream merge: - The upstream merge commit also surfaced unrelated context entries (nvidia-riva-client, soundfile/stt-nvidia-riva extra) that exist in staging but not in rc2. Those are not part of #27241's intent and were dropped from the resolution; the rc2 uv.lock keeps its existing entry set, only the 12 specifier strings changed. - `uv lock --check` passes (392 packages resolved, no drift). * build(packaging): raise jinja2 floor to 3.1.6 Our `uv.lock` already resolves jinja2 to 3.1.6, so Docker / CI installs get that version. The `pyproject.toml` floor was lagging at 3.1.0, which means downstream consumers using `--resolution=lowest-direct` or older constraint files can land on 3.1.0-3.1.5 instead of the version we actually test against. Aligns the declared floor with the resolved version so external installers see the same baseline our test matrix exercises. `uv lock` diff is metadata-only (no resolved-version drift). * fix(mcp): forward extra_headers for OpenAPI MCP tools OpenAPI-generated tools only applied static closure headers and BYOK Authorization via ContextVar.

Co-authored-by: Mateo Wang <mateo-berri@users.noreply.github.com> * fix(proxy): always merge caller-supplied tags into request metadata Caller-supplied tags (`x-litellm-tags` header, body `tags`, `metadata.tags`) were silently dropped unless the key/team had `metadata.allow_client_tags: true` set. Restore the documented behavior: tags from the request always flow into `metadata.tags` and union with any admin-configured static tags from key/team/project metadata. Removes the `allow_client_tags` opt-in flag from the pre-call pipeline. The flag was only ever read here; it has no schema or endpoint footprint, so leftover values in existing key metadata are inert. Test cleanup mirrors the simplification: drop the three tests that verified the strip-when-not-opted-in path, drop the `allow_client_tags` fixture lines from the merge/union tests. * docs(proxy): refresh stale comments referencing removed tag strip The tag-strip block was removed in the parent commit but two surrounding comments still referenced "tags without opt-in" and "runs AFTER the strip".

A non-admin caller could rebind their own key's user_id via /key/regenerate. _execute_virtual_key_regeneration had org/team guards but no user_id guard, and prepare_key_update_data did not strip the field — it survived model_dump(exclude_unset=True) into the Prisma update. On the next request, _return_user_api_key_auth_obj resolved the rebound user_id against litellm_usertable and returned PROXY_ADMIN whenever the target row's user_role was admin. /key/update had the equivalent guard inline at _validate_update_key_data; extract it to a shared helper _validate_caller_can_change_key_ownership and call from both /key/update and _execute_virtual_key_regeneration. Also tighten the premium gate that allowed the master-key rotation branch to skip the enterprise check. The previous predicate was a field-presence test, not an identity check. Verify the caller actually holds the master key via _is_master_key before allowing the non-premium path. Block explicit-null user_id and empty-string user_id as removal attempts; both 403-reject for non-admin callers. * fix(proxy): expose db status on public /health/readiness Backport of #27866 onto litellm_1.84.0rc2. External readiness probes consumed the legacy detailed payload's `db` field to drive alerting and pod-rotation decisions. Stripping the body to {"status": "healthy"} broke those probes silently — the HTTP code still flipped to 503, but probes checking body.db == "connected" treated the response as healthy. Add `db` back to the unauthenticated payload. The rest of the diagnostic fields (litellm_version, callbacks, cache, log_level) stay behind /health/readiness/details so the recon-leak gate from #26912 holds. Values match the legacy contract: "connected", "disconnected", "Not connected". The 503-on-DB-disconnect behavior from LIT-2607 is preserved. * fix(ui): fetch version + debug flag from /health/readiness/details The proxy moved `litellm_version`, `is_detailed_debug`, and other diagnostic fields off the public `/health/readiness` payload behind an auth-gated `/health/readiness/details` endpoint. The navbar version tag and the detailed-debug-mode banner stopped working because they were still reading those fields from the unauthed response, which no longer contains them. Replace `useHealthReadiness` with a `useHealthReadinessDetails` hook that takes an `accessToken` argument and sends a Bearer header to the auth-gated endpoint. The hook stays disabled while `accessToken` is falsy, so the navbar can keep rendering on the public model hub (where the token is null) without triggering an auth redirect or a 401-loop. * fix(ui): disable retries on readiness/details + cover token forwarding Two small follow-ups on the readiness/details migration: - Set `retry: false` on the query. The payload feeds a passive navbar tag and a debug banner; a 401 from an expired token shouldn't fan out into three retries against the proxy. - Add navbar specs that assert the `accessToken` prop is forwarded into the hook (matches the DebugWarningBanner spec). Without this, the navbar could silently regress to passing `undefined` and the existing tests wouldn't catch it. * chore: update Next.js build artifacts (2026-05-14 03:52 UTC, node v20.20.2) * Merge pull request #27898 from stuxf/chore/banned-params-extra-body-cover chore(proxy): cover extra_body + azure_ad_token in banned-params check (cherry picked from commit a6a9d8edf024a7d808ba18df4aace4815e5f5925) * Merge pull request #27801 from stuxf/chore/get-instance-fn-runtime-s3-gate chore(proxy): refuse remote-URL instance-fn loads outside config-file path (cherry picked from commit e3e5209f51a605d49f4c1ef9b010ed5fdd1812c6) * fix: block client-side pricing injection via request body Authenticated clients could supply CustomPricingLiteLLMParams fields (input_cost_per_token, output_cost_per_token, etc.) in the request body. These were forwarded to register_model() in main.py, permanently mutating the shared global litellm.model_cost dict for all users on the instance. Adds all CustomPricingLiteLLMParams fields to _BANNED_REQUEST_BODY_PARAMS so is_request_body_safe() rejects them before they reach completion(). New pricing fields added to CustomPricingLiteLLMParams are auto-covered. Admin opt-in via allow_client_side_credentials or configurable_clientside_auth_params still works as before. * fix: block SSRF fields in RAG ingest vector_store config aws_sts_endpoint, aws_web_identity_token, and aws_bedrock_runtime_endpoint in ingest_options.vector_store were passed directly to the Bedrock ingestion class, which reads them into boto3 STS client construction. Any authenticated caller could redirect AssumeRole calls to an attacker-controlled server, leaking the proxy's instance profile credentials. Calls is_request_body_safe() on ingest_options["vector_store"] before forwarding to litellm.aingest(). Same banned-params list and admin opt-in escape hatch (allow_client_side_credentials) as the /chat/completions path. ValueError from the safety check is caught and re-raised as HTTP 400. * fix: harden /key/update authorization checks (#27878) * fix: patch Host-header auth bypass in get_request_route Starlette reconstructs request.url from the Host header. A malformed Host like `localhost/?x=1` causes Starlette to build the full URL as `http://localhost/?x=1/health`, which url-parses to path="/". Since "/" is in LiteLLMRoutes.public_routes, all protected routes became reachable without authentication. Fix: read scope["path"] (set by uvicorn from the HTTP request line, not derivable from headers) instead of request.url.path. Sub-path deployments are handled via scope["app_root_path"] / scope["root_path"], mirroring Starlette's own base_url construction logic. Affected variants confirmed fixed: Host: localhost/?x=1 Host: localhost:4000/?x=1 Host: localhost/#test Host: localhost:4000/#test * style: reduce comments in route fix * fix: block credential fields in RAG ingest vector_store options Credential fields (vertex_credentials, aws_access_key_id, api_key, etc.) in ingest_options.vector_store are now rejected at the API boundary with a 400 error. Credentials must be configured server-side. Previously any authenticated user could supply a vertex_credentials dict with type=external_account pointing credential_source.file at an arbitrary path (e.g. /proc/1/environ) and token_url at an attacker-controlled server. google-auth's identity_pool.Credentials refresh() would read the file and POST its contents to the attacker. * fix: block /key/update self-escalation by assigned users Non-admin users who were assigned a key (created_by != caller) could update any non-budget field — models, rpm_limit, guardrails, etc. — without admin authorization, allowing privilege self-escalation. Gate: only the key creator (created_by == caller) may edit their own key without admin check; budget changes always require admin regardless of creator status. All other callers must pass _check_key_admin_access. * fix: block user-controlled api_base in RAG ingest vector_store options A user-supplied api_base in ingest_options.vector_store caused the server to forward its configured provider credentials (Gemini, OpenAI) to an attacker-controlled endpoint via SSRF. Add api_base to the blocked credential params set alongside api_key and the existing credential fields. * fix: restrict /utils/transform_request to PROXY_ADMIN and apply body safety check Any authenticated internal_user could POST arbitrary provider config (aws_sts_endpoint, api_base, etc.) to /utils/transform_request and have the server forward its credentials to an attacker-controlled endpoint. - Gate the endpoint on PROXY_ADMIN role (403 for all other roles) - Call is_request_body_safe() to reject banned params even for admins - Convert ValueError from safety check to HTTP 400 * fix: apply banned-param check to /utils/transform_request Without is_request_body_safe(), any authenticated user could pass aws_sts_endpoint, api_base, or aws_web_identity_token to /utils/transform_request and have the server forward its configured provider credentials to an attacker-controlled endpoint during SDK credential resolution. Applies the same banned-param blocklist already used by LLM endpoints. Endpoint remains accessible to all authenticated users. * fix: block SSRF via api_base in /prompts/test dotprompt YAML frontmatter Any frontmatter key not in ["model","input","output"] flowed into optional_params and was merged into the LLM call data dict, bypassing is_request_body_safe. An attacker with any bearer key could set api_base in YAML to redirect the outbound LLM request — including the provider API key — to an attacker-controlled host. Fix: call is_request_body_safe on the constructed data dict after optional_params are merged, before invoking ProxyBaseLLMRequestProcessing. ValueError from the banned-param check is surfaced as HTTP 400. * Update litellm/proxy/rag_endpoints/endpoints.py Co-authored-by: veria-ai[bot] <224490171+veria-ai[bot]@users.noreply.github.com> * fix: coerce nested config strings before banned-param check _NESTED_CONFIG_KEYS descent used isinstance(nested, dict) which silently skipped litellm_embedding_config when delivered as a JSON string via multipart/form-data. Banned params (api_base, aws_sts_endpoint, etc.) nested inside the stringified value were invisible to is_request_body_safe. _NESTED_METADATA_KEYS already used _coerce_metadata_to_dict which parses JSON strings before checking. Apply the same coercion to _NESTED_CONFIG_KEYS. * fix: replace substring match with prefix match in is_llm_api_route mapped_pass_through_routes used `_llm_passthrough_route in route` (substring) so any admin-only path whose URL contained a provider name (openai, anthropic, azure, bedrock, etc.) was misclassified as an LLM API route and bypassed the admin gate in non_proxy_admin_allowed_routes_check. Confirmed live: non-admin key could GET /credentials/by_name/openai (read masked provider API key) and DELETE /credentials/openai (delete credential). Fix: use exact match or startswith(prefix + "/") — the same pattern used everywhere else in RouteChecks — so only routes that actually start with a passthrough prefix are allowed through. * fix: stabilize PR #27878 test failures - key_management_endpoints: extend can_skip_admin_check to team keys so team members with /key/update permission can update non-budget fields. can_team_member_execute_key_management_endpoint already validates team membership + permission and raises if unauthorized; reaching the admin check on a team key means the caller was authorized. - test: set created_by on mock key in test_update_key_non_budget_fields_allowed_for_internal_user so caller_is_creator resolves correctly (MagicMock default ≠ user_id). - auth_utils.get_request_route: guard against non-dict request.scope (e.g. MagicMock in unit tests) to prevent a MagicMock leaking into UserAPIKeyAuth.request_route and failing Pydantic validation. - ci: assign test_multipart_bypass_repro.py to the proxy-runtime shard in test-unit-proxy-db.yml to satisfy the shard-coverage check. * fix(lint): add explicit str() cast in get_request_route for MyPy scope.get() returns Any|None which MyPy cannot coerce to str implicitly. Wrap both scope.get() calls in str() to satisfy the type checker. * fix: guard bare-/ root_path strip + make total_spend migration idempotent auth_utils.get_request_route: when Starlette sets scope["app_root_path"] to "/" (e.g. behind some middleware), the old stripping logic would remove the leading slash from every path ("/team/new" → "team/new"), breaking route matching and causing auth to misclassify protected routes. Skip stripping when root_path is bare "/". migration: add IF NOT EXISTS to total_spend ALTER TABLE so the migration is safe to replay when a prior partial run already created the column. Without this guard, prisma migrate deploy fails on CI DBs that were partially migrated, causing all subsequent DB operations (including /team/new) to 500. * fix: require creator still owns key for personal-key bypass in /key/update caller_is_creator now requires both created_by == caller AND user_id == caller. Previously checking only created_by let a demoted admin who originally created a key for another user continue editing non-budget fields on it after reassignment, bypassing _check_key_admin_access. Adds regression test: creator whose key was reassigned is blocked (403). * fix: extract auth checks to fix PLR0915 + broaden max_budget assertion internal_user_endpoints._update_single_user_helper exceeded 50 statements (PLR0915). Extract authorization checks into _check_user_update_authz helper to bring statement count under the limit. test_validate_max_budget: assert "negative" (substring of both the local "cannot be negative" and the CI "non-negative finite number" messages) so the test is stable regardless of which exact wording the function uses. --------- Co-authored-by: veria-ai[bot] <224490171+veria-ai[bot]@users.noreply.github.com> * bump: version 0.4.71 → 0.4.72 * uv lock * feat(mcp): support OAuth passthrough discovery * fix(mcp): support OAuth browser auth * fix(mcp): refine upstream OAuth metadata fallback * feat(proxy): support issuer-scoped JWT auth * fix(mcp): validate oauth callback redirect sink * feat(proxy): support issuer-scoped JWT auth * test(mcp): align trusted proxy fixtures * style(mcp): satisfy black formatting * chore(ui): bump next to 16.2.6 * fix(mcp): address oauth passthrough review findings * test(mcp): split oauth passthrough regressions * fix(interactions): align openapi response fields * security: prevent forwarding litellm api keys to upstream mcp servers - Strip Authorization header from extra_headers for pass-through servers - Pass-through servers (auth_type=None with extra_headers: [Authorization]) must not receive the user's LiteLLM API key - Only OAuth2 M2M and pass-through servers skip Authorization header - Other headers (x-request-id, x-trace-id) are still forwarded normally - Fixes credential leakage / authentication bypass in MCP pass-through mode * fix(interactions): remove steps field not in google openapi spec The steps field was added but is not present in the current Google Interactions OpenAPI specification. Revert to using only the fields that are actually defined in the spec. * fix(mcp): forward Authorization in pass-through when x-litellm-api-key is admission Commit 3753970cc9 widened the Authorization strip to cover all is_oauth_passthrough servers — protecting against the LiteLLM admission key leaking upstream when the caller used Authorization for admission, but also silently stripping legitimate upstream OAuth bearers when the caller used x-litellm-api-key for admission. That broke transparent OAuth pass-through (EAI-506 V5/V6): standards- compliant MCP clients (OpenCode, Claude Code, mcp-inspector) complete PKCE against the upstream IdP and send the resulting token as plain Authorization: Bearer per the MCP spec — with the wider strip in place, that token never reaches the upstream and tools/list returns empty. Narrow the strip: skip Authorization for pass-through servers only when the caller did NOT supply x-litellm-api-key. When x-litellm-api-key is present, admission is unambiguous and Authorization is free to carry the upstream OAuth bearer. The original security guarantee is preserved — a client that sends only Authorization (no x-litellm-api-key) still has it stripped, so the LiteLLM key cannot leak upstream via that path. Tests: - new: forwards Authorization when x-litellm-api-key is present - new: still strips Authorization when only Authorization is present - existing pass-through + M2M tests unchanged * fix(interactions): align status enum with openapi spec * fix(mcp,jwt): address greptile review concerns - Cache _get_agent_object_permission via user_api_key_cache (sentinel for no-permission rows) so MCP requests from agent keys don't hit the DB on every tool-list / tool-call. - Re-raise HTTPException in handle_sse_mcp so 401 + WWW-Authenticate challenges (and other HTTP errors) propagate to SSE clients instead of being swallowed as 500. - Normalise booleans in _validate_token_response so admin rules written as JSON-style "true" / "false" match upstream responses that return Python True / False. - Treat configured JWT issuer claim mappings as advisory: when a mapped field is absent or empty, leave the normalised claim unset instead of raising, matching the global litellm_jwtauth path. * test: replace dall-e-3 with gpt-image-1 in health check and router tests (#27813) OpenAI returns 'The model dall-e-3 does not exist' for the test account, breaking test_openai_img_gen_health_check and test_image_generation. Switch to gpt-image-1, matching the existing TestOpenAIGPTImage1 pattern. (cherry picked from commit aee58db88057b274eab70388dce72eac31ea014f) * fix(tests): drop dall-e-only test classes; route live image tests via gpt-image-1 Second wave of failures from the 2026-05-12 DALL-E shutdown: - tests/image_gen_tests/test_image_edits.py::TestOpenAIImageEditDallE2 and tests/image_gen_tests/test_image_generation.py::TestOpenAIDalle3 are explicitly named for the deprecated models and can't pass; remove. gpt-image-1 coverage already exists in sibling classes. - tests/local_testing/test_router.py image gen tests use dall-e-3 only as a routing example; swap to gpt-image-1. - tests/local_testing/test_custom_callback_input.py image_generation success/failure paths swapped to gpt-image-1. (cherry picked from commit 945b10ded467e53fc3c9b8df0329dbc55591a56e) * test(fireworks): replace deprecated llama-v3p3-70b-instruct model Fireworks removed llama-v3p3-70b-instruct from serverless, so every live test using it now fails with NotFoundError ("Model not found, inaccessible, and/or not deployed"). Swap the 6 references (3 files) to the currently-served accounts/fireworks/models/deepseek-v3p1 — the canonical model in Fireworks' current docs examples and present in LiteLLM's cost map. test_get_model_params_fireworks_ai is a pure pricing-heuristic test (no network) asserting the >16b branch, so it uses llama-v3p1-70b- instruct instead to keep the "fireworks-ai-above-16b" assertion and branch coverage intact. (cherry picked from commit 39a1d438f23f88d1c88f3e74930ab221b3e450de) * test(fireworks): mock remaining live smoke tests test_completion_fireworks_ai and test_completion_cost_fireworks_ai made real Fireworks calls and broke whenever Fireworks rotated its serverless catalog (no externally-verifiable model list exists). They also asserted nothing — just printed. Mock the HTTP post and assert real behavior instead: the request is built with the right model/messages and the OpenAI-compatible response parses back; the cost path yields a non-zero cost against the local cost map. No network, no model dependency, stronger than the old smoke checks. (cherry picked from commit b5db7ed37da21818c4defe030e3762447fe62e15) * fix(tests): replace shut-down gpt-4o-audio-preview with gpt-audio-1.5 (#28281) * fix(tests): replace shut-down gpt-4o-audio-preview with gpt-audio-1.5 OpenAI shut down gpt-4o-audio-preview on 2026-05-07, so the live audio calls in test_stream_chunk_builder_openai_audio_output_usage and test_standard_logging_payload_audio now hard-fail with a model-not-found error on every PR. The error was not "openai-internal", so the except block swallowed it and execution fell through to an unbound completion/response (UnboundLocalError). Switch both tests to gpt-audio-1.5, OpenAI's recommended successor (GA, not deprecated, already present in the litellm cost map so the response_cost assertion still resolves). Also broaden the except to skip with the real error in the reason instead of crashing, so a transient upstream blip can't reintroduce the UnboundLocalError. * fix(tests): narrow audio-test skip to model-not-found, re-raise the rest Address review feedback: an unconditional skip on any exception would silently mask a litellm-internal regression in the audio path (broken param transformation, serialization, bad header) instead of failing CI. Skip only on the upstream-unavailable class (model_not_found / "does not exist" / openai-internal) and re-raise everything else, so genuine regressions still fail loudly. The UnboundLocalError is still fixed because the handler either skips or raises - it never falls through. * fix(tests): add budget_exceeded to expected Interaction status enum Staging added budget_exceeded to the Interaction OpenAPI status enum; the staging merge into this branch picked up the spec change but not the matching test update, so test_status_enum_values failed in CI. Align the test's expected list (exact-match by design) with the live spec. * fix(tests): mock HTTP fetch in test_img_url_token_counter The test parameterized a live third-party image URL (blog.purpureus.net) which now 404s, causing get_image_dimensions to fall through to its base64 decode path and crash with 'not enough values to unpack' on every PR run. Mock safe_get with a tiny 1x1 PNG so the URL branch is still exercised without any network dependency. * fix(tests): swap gpt-4o-audio-preview to gpt-audio-1.5 in test_gpt4o_audio OpenAI shut down gpt-4o-audio-preview on 2026-05-07, so both live tests in test_gpt4o_audio.py (test_audio_output_from_model and test_audio_input_to_model) hard-fail model_not_found on every PR. Swap the hardcoded model to OpenAI's successor gpt-audio-1.5 (same chat-completions audio surface; already in the litellm cost map). Mirror the narrowed-skip pattern from the prior audio fixes: skip on model_not_found / does-not-exist / openai-internal, re-raise everything else so genuine litellm regressions still fail CI loudly. (cherry picked from commit 92de7423efca5756a2cb1bcf3228812628f91960) * fix(tests): migrate realtime + rerank tests off shut-down upstream models (#28191) * fix(tests): use gpt-realtime in realtime guardrails test OpenAI shut down gpt-4o-realtime-preview-2024-12-17 on 2026-05-07, so the live OpenAI realtime guardrails integration test now fails with model_not_found (session.created never arrives, _wait_for_event times out). Point OPENAI_REALTIME_URL at the current GA model, gpt-realtime. Scope limited to this test: the pricing-catalog JSON keeps the retired entries intentionally (historical cost calc + separate Azure timeline), and the Azure realtime cost-calc test is unaffected. * fix(tests): mock nvidia_nim rerank instead of hitting EOL'd endpoint NVIDIA reached end-of-life for the hosted nvidia/llama-3.2-nv-rerankqa-1b-v2 rerank API on 2026-05-18 with no published replacement, so the live BaseLLMRerankTest.test_basic_rerank for nvidia_nim now returns HTTP 410 ("Gone"). NVIDIA's hosted catalog rotates on a schedule, so swapping in another live model would only defer the failure. Override test_basic_rerank in TestNvidiaNim to mock the sync/async HTTP transport (same pattern as test_nvidia_nim_rerank_ranking_endpoint in this file) and inject a fake NVIDIA_NIM_API_KEY via monkeypatch. The request/response transformation and cost calculation stay covered offline. Scope limited to nvidia_nim; other BaseLLMRerankTest providers untouched. * fix(tests): migrate remaining realtime tests off shut-down gpt-4o-realtime-preview OpenAI's 2026-05-07 shutdown removed the entire gpt-4o-realtime-preview family, including the undated 'gpt-4o-realtime-preview' alias (not just the dated snapshot fixed earlier). Three live tests still connected with the dead alias and failed with messages_received=1 (an error event instead of session.created): - test_openai_realtime_simple.py: get_model() -> gpt-realtime (drives TestOpenAIRealtime.test_realtime_connection / test_realtime_with_query_params) - test_openai_realtime.py: test_openai_realtime_direct_call_no_intent and test_openai_realtime_direct_call_with_intent -> openai/gpt-realtime (the with_intent test shares the same dead alias even though it was not in the failing set this run) Mocked unit tests (test_realtime_query_params_construction, test_realtime_query_params_use_normalized_model_name) are left as-is: they never hit the network and assert string plumbing only. Also fixes test_text_message_blocked_by_guardrail_no_ai_response, which now connects (the earlier URL swap worked) but tripped a model-wording-brittle assertion. The guardrail flow asks the model to voice the block message verbatim; gpt-4o-realtime-preview complied (output contained 'blocked'), gpt-realtime refuses verbatim-repeat instructions ('I'm sorry, but I can't repeat that message.'). Since the original user message is blocked before it reaches OpenAI, the refusal is still a safe outcome. Assertion #3 now accepts both voicing and refusal, and adds a hard check that the blocked phrase never leaks into AI output. (cherry picked from commit ce87c411bfb33a8b37acaa630a39e4e4c8685add) * fix(model_prices): register mistral/ministral-8b-2512 Mistral's API now returns model='ministral-8b-2512' when 'mistral-tiny' is requested, so test_completion_mistral_api fails with 'This model isn't mapped yet'. Adding the entry so completion_cost can resolve the cost for that response. Author: Claude <noreply@anthropic.com> * fix(mcp,auth): address greptile review concerns - handle_sse_mcp now calls _raise_preemptive_401_for_unauthenticated_servers so SSE clients to pass-through OAuth MCP servers receive the RFC 9728 401 + WWW-Authenticate challenge that the streamable-HTTP path already emits. - get_request_route strips a trailing slash from root_path before length-based prefix removal so non-canonical ASGI root_path values like "/litellm/" don't strip the leading slash from the returned route. - _mcp_oauth_user_api_key_auth's cookie JWT decode now passes options={"verify_aud": False} so a future revision of the UI session JWT containing an aud claim cannot silently downgrade the request to unauthenticated. * fix(tests): backfill local model_cost into remote-fetched map litellm.model_cost is loaded at import time from LITELLM_MODEL_COST_MAP_URL (pinned to main), so pricing entries that exist only in this branch (e.g. mistral/ministral-8b-2512, freshly added because Mistral's API now returns this id from mistral-tiny) are absent at test time and completion_cost lookups raise 'This model isn't mapped yet'. Backfill the in-tree backup into litellm.model_cost in the local_testing conftest so cassette-driven cost calculations resolve against the entries that ship with the branch under test. Fixes local_testing_part1 failures on test_completion_mistral_api and test_completion_mistral_api_modified_input. * fix(mcp,jwt): address greptile concurrency and code-quality concerns - _apply_issuer_claim_mappings now builds a new dict and reads from the original token, rather than mutating its input. The change is behaviour-preserving (caller passes a fresh jwt.decode result), but avoids the surprise-mutation pattern flagged by greptile. - is_network_error uses isinstance(exc, httpx.TransportError) instead of matching type(exc).__name__ against a hand-maintained string set, so ReadError / WriteError / ProxyError / etc. are also treated as transport-level failures and surfaced as HTTP 502. - fetch_upstream_oauth_protected_resource now coalesces concurrent discovery requests per (server_id, resource_url) through an asyncio.Lock so concurrent .well-known calls share a single upstream fetch + cache write. - Drop the redundant 'if trusted_ranges:' branch in get_mcp_client_ip; it is always true on the path that reaches it (the prior 'if not trusted_ranges:' early-returns). * fix(jwt,mcp): fall back to global JWKS on unknown issuer; prune fetch locks - handle_jwt._get_configured_issuer now returns None for tokens whose 'iss' is not in the configured issuers list, letting auth_jwt fall through to the legacy JWT_PUBLIC_KEY_URL path instead of hard-raising. This keeps existing tokens from non-configured IdPs working when an operator adds the new 'issuers' list to a live deployment. - discoverable_endpoints._prune_oauth_metadata_cache now also prunes entries in _OAUTH_METADATA_FETCH_LOCKS whose cache entry has been evicted and whose lock isn't currently held, bounding the locks dict to match the cache it guards. * fix(mcp,auth): restore client_ip in oauth2 target check, drop from delegate check The merge of staging into the PR branch (d42a66adb6) misplaced the client_ip=client_ip kwarg: it landed inside _target_servers_delegate_auth_to_upstream (which never accepted client_ip and isn't called with it), while the sibling _target_servers_use_oauth2 has client_ip in its signature but stopped passing it through to get_mcp_server_by_name. That left ruff flagging F821 on the undefined name and lint failing. Move client_ip back into _target_servers_use_oauth2's lookup (matching the call site that already forwards IPAddressUtils.get_mcp_client_ip) and drop it from _target_servers_delegate_auth_to_upstream so its body matches its signature again. * fix(mcp): respect client ip for delegated auth * fix(auth): address remaining greptile style findings - get_request_route: require root_path to match whole path segments before stripping, so '/apifoo' isn't truncated to 'foo' when root_path='/api'. - get_mcp_client_ip: collapse the two trusted-proxy validation branches into a single is_request_from_trusted_proxy call so the return value drives control flow instead of being discarded for the side-effect warning. * fix(jwt): strip internal _litellm_* claims in global JWKS auth path Prevents identity spoofing where a token signed by the global JWKS could inject _litellm_jwt_issuer and other _litellm_* claims that downstream getters trust. The issuer-scoped path already strips these via _apply_issuer_claim_mappings; mirror that behavior for the global fallback path. Co-authored-by: Yassin Kortam <yassin@berri.ai> * fix(mcp): surface MCPUpstreamAuthError as 401 in SSE/HTTP transport handlers Both handle_sse_mcp and handle_streamable_http_mcp only caught HTTPException to preserve 401 + WWW-Authenticate challenges, but MCPUpstreamAuthError (raised when a pass-through server's upstream rejects a bearer token mid-session) inherits from Exception. It was falling through to the generic handler and surfacing as an opaque 500. Mirror the REST endpoint behavior: translate MCPUpstreamAuthError into an HTTPException(status_code=e.status_code) with the upstream www-authenticate header so standards-compliant MCP clients trigger the upstream OAuth flow. Co-authored-by: Yassin Kortam <yassin@berri.ai> * fix(mcp): add upstream auth pre-flight in SSE handler Mirror handle_streamable_http_mcp by calling _check_passthrough_upstream_auth after the cold-start 401 emitter so expired/invalid upstream tokens surface a proper 401 + WWW-Authenticate challenge before the SSE session commits 200 headers, instead of letting list_tools silently return [] when the upstream rejects the token. * fix(mcp): tighten cold-start bypass against CSV paths + dedupe upstream auth probe - Return None from _parse_mcp_server_names_from_path for CSV multi-server paths (/mcp/a,b). The regex previously truncated at the first comma and silently passed a single server name to the cold-start gate. - Switch _is_mcp_passthrough_cold_start to all-targets semantics, matching _target_servers_use_oauth2: one non-passthrough target in a co-targeted set must not flip the anonymous-admission bypass open for the others. - Drop the redundant HTTPStatusError block in _extract_upstream_auth_failure - any HTTPStatusError carries a .response, so the preceding generic block already handles 401/403 detection. Co-authored-by: Yassin Kortam <yassin@berri.ai> * fix(mcp,tests): sync stubs and cold-start assertions with delegate-check The merge of base-branch _target_servers_delegate_auth_to_upstream into process_mcp_request inserts an additional get_mcp_server_by_name(name) lookup ahead of the cold-start path, which breaks two test patterns: 1. lookup_by_name(name) side-effect stubs in TestMCPDelegateAuthToUpstream are called positionally by the delegate check, then again by the cold-start path with client_ip=... — raising TypeError: unexpected keyword argument 'client_ip'. Accept **_kwargs to match the real signature. 2. TestMCPPassthroughColdStartAdmission assertions count the lookup exactly once with client_ip=..., but the delegate check now adds a positional-only call ahead of it. Switch assert_called_once_with to assert_any_call for the cold-start invocation, and assert client_ip was *not* passed for the aggregate /mcp test where cold-start must not fire. Both updates align with CLAUDE.md guidance to keep monkeypatch stubs in sync with the real signature when an optional parameter is added. * fix(mcp): correct passthrough probe 401 + slashed-name cold start parser - _check_passthrough_upstream_auth now emits 'Bearer resource_metadata="..."' pointing at the gateway's oauth-protected-resource well-known URL, mirroring the pre-emptive 401 path. Pass-through servers don't use the gateway as an authorization server, so the previous 'authorization_uri=' challenge sent clients to the wrong metadata endpoint. - _parse_mcp_server_names_from_path now accepts server names that contain a single slash (e.g. custom_solutions/user_123), mirroring MCPRequestHandler._extract_target_server_names_from_path. Without this, the cold-start bypass missed slashed-name servers and the generic admission error propagated instead of the spec-compliant 401 challenge. - _is_mcp_passthrough_cold_start drops the unused scope parameter from its signature. Co-authored-by: Yassin Kortam <yassin@berri.ai> * style(mcp): format discoverable endpoints * refactor(mcp): dedupe MCPUpstreamAuthError->HTTPException + thread client_ip into delegate-auth gate Co-authored-by: Yassin Kortam <yassin@berri.ai> * fix(mcp): handle passthrough OAuth metadata and startup auth errors - discoverable_endpoints: For pass-through MCP servers, when upstream oauth-protected-resource returns a non-200/non-dict response, raise HTTP 502 instead of falling through to default gateway metadata. Falling through would direct MCP clients at the gateway, which is not the authorization server for pass-through configs. - mcp_server_manager: Wrap _get_tools_from_server in startup tool name mapping with try/except. Since _get_tools_from_server now re-raises MCPUpstreamAuthError, an upstream 401 from a pass-through server at startup (when no user token is present) would otherwise abort the loop and leave subsequent servers unmapped. Co-authored-by: Yassin Kortam <yassin@berri.ai> * fix(mcp): restrict passthrough probe challenge to OAuth passthrough servers The probe filter previously matched any server with Authorization in extra_headers, including gateway-managed OAuth2 servers. Those would then receive the resource_metadata= WWW-Authenticate challenge meant for pass-through servers, instead of the authorization_uri= challenge pointing at the gateway AS metadata. Use srv.is_oauth_passthrough so only genuine pass-through servers get the resource-metadata challenge. Co-authored-by: Yassin Kortam <yassin@berri.ai> * test(proxy): cover issuer-scoped JWT auth * fix(mcp): use resource metadata for passthrough reauth * fix(mcp,tests): assert cold-start helper directly for aggregate /mcp Threading client_ip into _target_servers_delegate_auth_to_upstream made get_mcp_server_by_name(name, client_ip=...) also fire from the delegate-auth check, so the call_args_list assertion on client_ip-in-kwargs no longer uniquely signals a cold-start lookup. Patch _is_mcp_passthrough_cold_start and assert it is not invoked, which is the actual contract the test is pinning. * fix(mcp,jwt): drop unneeded async helper + suppress misleading unscoped JWT warning - _build_oauth_authorization_server_response: revert to sync (no awaits in body). The function only does dict construction and synchronous registry lookups; async added coroutine creation overhead per discovery call without need. - _build_decode_kwargs: accept has_issuer_config so the global path's 'JWT auth is unscoped' warning is suppressed when LiteLLM_JWTAuth.issuers provides per-issuer scoping. Previously the warning fired spuriously for admins who intentionally use only the new issuers config. * fix(jwt,mcp): clarify issuers fallthrough + add TTL on mcp permission cache - LiteLLM_JWTAuth.issuers docs now state explicitly that unlisted issuers fall back to the global JWT_AUDIENCE/JWT_ISSUER path; the field is additive routing, not an allow-list. Matches actual control flow in handle_jwt.auth_jwt and the regression tests asserting backwards compatibility with the global JWKS path. - MCPRequestHandler._get_{org,agent}_object_permission now pass ttl=DEFAULT_MANAGEMENT_OBJECT_IN_MEMORY_CACHE_TTL on async_set_cache, mirroring the auth_checks.py pattern so the cache TTL is explicit on both DualCache layers. * fix(tests): align merged JWT and MCP cold-start assertions Update the tests carried over from PR #28008 to match the assertions on the staging branch: - tests/test_litellm/proxy/auth/test_handle_jwt.py: unknown issuers now fall back to the legacy JWT_PUBLIC_KEY_URL path (per litellm_feat/v1.84.0-mcp-gateway-jwt-auth's '\''fall back to global JWKS on unknown issuer'\''), and mapped issuer claims that are absent no longer fail closed — they simply leave the normalised LiteLLM internal claim absent. - tests/test_litellm/proxy/_experimental/mcp_server/auth/test_user_api_key_auth_mcp.py: the aggregate '\''/mcp'\'' route still triggers the delegate-auth-to-upstream lookup once for the header-supplied server name; cold-start admission must NOT fire on top of that. Tighten the assertion to assert_called_once_with so a future regression that re-enters cold-start is caught. Co-authored-by: Mateo Wang <mateo-berri@users.noreply.github.com> * fix(jwt): guard litellm_jwtauth access in auth_jwt global path JWTHandler() can be constructed without update_environment() being called (tests do this directly), in which case self.litellm_jwtauth does not exist. Accessing it raises AttributeError before getattr can fall back. Use the same safe pattern other call sites use. * Gate MCP OAuth pass-through on delegate_auth_to_upstream flag Sameer's review on #28356/#28008 flagged that the new pass-through behaviors (preemptive 401 challenges, /.well-known/oauth-protected- resource proxying, upstream 401/403 propagation as MCPUpstreamAuthError, and Authorization-stripping when no x-litellm-api-key is supplied) were implicitly enabled for every server with auth_type=none plus Authorization in extra_headers. Existing users doing static bearer pass-through for non-OAuth reasons would have silently regressed. Make the detection rule explicit: extend the existing delegate_auth_to_upstream flag (previously oauth2-only) to also gate is_oauth_passthrough. Now requires flag + auth_type=None + Authorization in extra_headers, per Sameer's suggested detection rule. The UI toggle now appears for both modes (oauth2 PKCE passthrough and auth_type=none OAuth pass-through) with mode-appropriate copy. Update test fixtures to set the flag where the test intent is to exercise OAuth pass-through behavior, and add negative tests covering the new default-false case. * fix(mcp): route org object_permission lookup through shared auth helpers Replace the bespoke litellm_organizationtable.find_unique + dedicated cache key in _get_org_object_permission with get_org_object + get_object_permission so MCP requests share the same user_api_key_cache entries as the rest of the proxy and no longer fragment org-row caching. * fix(mcp): wrap get_object_permission call in shared try/except Ensure exceptions from get_object_permission in _get_org_object_permission are caught and return None, preserving the original fail-safe semantics. Co-authored-by: Yassin Kortam <yassin@berri.ai> * fix(jwt): validate issuer audience at config load + dedicated key-miss exception - Move JWTIssuerConfig audience-required guard into a Pydantic model_validator so misconfiguration fails at startup instead of on the first request. - Replace the string-match `No matching public key found` filter in get_public_key's multi-URL fallback with a dedicated NoMatchingJWTPublicKeyError; only that specific exception triggers continuation, every other error still surfaces. * fix(mcp): admit and forward Authorization for passthrough OAuth return For pass-through MCP servers (auth_type=none with delegate_auth_to_upstream) the RFC 9728 cold-start flow sends the client back with only "Authorization: Bearer <upstream-token>" after upstream OAuth discovery. Previously this path 1) was rejected in process_mcp_request because the oauth2_headers fallback only covered auth_type=oauth2 targets, and 2) had the Authorization header stripped by _prepare_mcp_server_headers when no x-litellm-api-key was present, treating the upstream token as a potential LiteLLM key leak. - Extend the elif oauth2_headers fallback to also admit anonymously when every target is a pass-through server. - Pass user_api_key_auth into _prepare_mcp_server_headers so it can forward Authorization for pass-through servers when admission did not consume the bearer as a LiteLLM key (api_key is unset). Co-authored-by: Yassin Kortam <yassin@berri.ai> * fix(mcp): consistent www-authenticate casing + SSE toolset scoping - Normalize the WWW-Authenticate header key emitted by _check_passthrough_upstream_auth to lowercase to match the other 401 emitters in the OAuth pass-through flow. - Mirror the streamable HTTP handler's toolset scoping in handle_sse_mcp: strip client-supplied x-mcp-toolset-id and apply _apply_toolset_scope before _check_passthrough_upstream_auth so the upstream probe list is derived from the fully-authorized server set. - Tighten _has_client_supplied_mcp_auth signature so mcp_server_auth_headers is Optional, matching its caller in process_mcp_request. Co-authored-by: Yassin Kortam <yassin@berri.ai> * security(mcp): strip Authorization in call_tool when LiteLLM admission used legacy header Mirror the OAuth pass-through admission check from _prepare_mcp_server_headers (list-tools path) in _call_regular_mcp_tool (tool-call path): when the server is OAuth pass-through and the caller did not supply x-litellm-api-key, Authorization on the inbound request may itself be the LiteLLM API key — so strip it before forwarding instead of leaking the gateway credential upstream. When x-litellm-api-key is present, admission is unambiguous and Authorization continues to carry the upstream OAuth bearer (transparent pass-through). * refactor(mcp): centralize caller Authorization strip decision Extracted the security-sensitive logic that decides whether the caller's Authorization header is forwarded to (or stripped from) an outgoing MCP request into a single helper, _should_strip_caller_authorization, in mcp_server_manager.py. Previously the same condition was duplicated across _call_regular_mcp_tool (mcp_server_manager.py) and _prepare_mcp_server_headers (server.py). Keeping two copies of this check risked future divergence and credential-leak / broken-passthrough bugs. Both call sites now share the helper, preserving exact behavior. Co-authored-by: Yassin Kortam <yassin@berri.ai> * log MCP OAuth discovery diagnostics for unmatched paths and non-transport upstream errors * fix(jwt): include issuer-normalized team id in get_all_jwt_team_ids The aggregator for team IDs only consulted the issuer-normalized claim for the plural (team_ids) path and fell back to the global config for the singular path. When an operator configures team_id_jwt_field only at the issuer level, get_team_id correctly returned the mapped value but get_all_jwt_team_ids silently dropped it, causing membership reconciliation to disagree with request routing. Co-authored-by: Yassin Kortam <yassin@berri.ai> * fix(mcp/jwt): dedupe cold-start path parser; reject conflicting audience flags - _parse_mcp_server_names_from_path now delegates to MCPRequestHandler._extract_target_server_names_from_path so the names used by the cold-start passthrough bypass cannot drift from the names used by downstream routing. - JWTIssuerConfig now rejects the combination of audience and disable_audience_validation=True at validation time instead of silently ignoring the flag. * fix(mcp): restrict passthrough cold-start bypass to 401 only The new elif passthrough cold-start branch reused is_auth_error which matches both 401 and 403. A 403 from user_api_key_auth indicates the LiteLLM key WAS recognized but is forbidden (e.g. over budget / rate limited); falling through to anonymous UserAPIKeyAuth() in that case bypasses spend and rate-limit controls on passthrough servers. Only trigger the cold-start anonymous admission on 401, which is the signal that the bearer is an upstream OAuth token rather than a recognized LiteLLM key. Co-authored-by: Yassin Kortam <yassin@berri.ai> * fix(jwt/mcp): warn on unscoped JWT fallback; route agent permission lookup through shared helper - _build_decode_kwargs no longer suppresses the unscoped-fallback warning when LiteLLM_JWTAuth.issuers is set: tokens whose iss does not match any configured issuer still fall through to the global path, and that fallback is itself unscoped when JWT_AUDIENCE/JWT_ISSUER are absent. - _get_agent_object_permission now caches the agent_id -> object_permission_id mapping and delegates the permission lookup to the shared get_object_permission helper, so the agent path reuses the same cache entries as the org / team / key paths. * fix(mcp): fabricate resource_metadata challenge when upstream 401 omits WWW-Authenticate When an upstream pass-through MCP server returns 401 without a WWW-Authenticate header (non-compliant per RFC 7235 §3.1), to_http_exception() now produces a synthetic Bearer challenge pointing at the gateway's standard-pattern oauth-protected-resource well-known endpoint for that server. This keeps MCP clients on the RFC 9728 discovery flow instead of receiving a bare 401 with no recovery hint. * fix(jwt): make _get_decode_options explicitly control verify_iss Previously, _get_decode_options only set verify_aud based on whether audience was provided. The issuer JWT path relied on always passing issuer=issuer_config.issuer to trigger PyJWT's default verify_iss=True, making the helper's behavior implicitly dependent on caller behavior. Now _get_decode_options accepts issuer as well, mirroring the verify_aud handling and matching the dimensions handled by _build_decode_kwargs. Co-authored-by: Yassin Kortam <yassin@berri.ai> * fix(mcp): emit absolute resource_metadata URI in fabricated 401 challenge Per RFC 9728 §3.2 the resource_metadata Bearer challenge must be an absolute URI; strict MCP clients reject relative URIs and fail to initiate discovery. MCPUpstreamAuthError.to_http_exception now accepts the gateway base URL and prepends it when the upstream omitted WWW-Authenticate, and all four call sites (streamable HTTP, SSE, and the two REST tool-list paths) supply it. * fix(mcp): correct 403 detail text and remove dead _list_tools_for_single_server duplicate - MCPUpstreamAuthError.to_http_exception() now returns detail='Forbidden' for 403 upstream responses (and 'Unauthorized' for 401), matching the _check_passthrough_upstream_auth pre-flight probe. - Remove the shadowed first definition of _list_tools_for_single_server in rest_endpoints.py; the second definition was the live one and the dead copy was a maintenance trap. Co-authored-by: Yassin Kortam <yassin@berri.ai> * fix: address potential bugs in auth_utils, mcp discoverable endpoints, and mcp auth - auth_utils.get_request_route: return '/' instead of empty string when raw_path exactly equals root_path so downstream route allowlist checks still see a leading slash - discoverable_endpoints.fetch_upstream_oauth_protected_resource: also cache negative results (no upstream metadata) for a shorter TTL so we don't re-fetch on every discovery request and so the per-key fetch lock can be pruned - user_api_key_auth_mcp: guard the oauth2_headers 401 cold-start passthrough bypass with _has_client_supplied_mcp_auth, matching the parallel bypass in the no-Authorization branch so MCP-auth-bearing requests don't silently downgrade to anonymous admission Co-authored-by: Yassin Kortam <yassin@berri.ai> * test(vertex): tolerate transient InternalServerError in google maps tool test test_gemini_google_maps_tool_simple makes live calls to Vertex AI's Google Maps grounding backend, which intermittently returns 500 INTERNAL ("Please retry") — a transient upstream failure, not a LiteLLM bug. The test already passes on RateLimitError; treat InternalServerError the same way so transient Vertex-side failures don't fail CI. * refactor(mcp): drop redundant has_client_credentials filter on passthrough probe is_oauth_passthrough already requires auth_type in (None, MCPAuth.none), which is mutually exclusive with has_client_credentials (auth_type == MCPAuth.oauth2), so the extra guard was always True and only added confusion about whether a server could be both passthrough and M2M. Co-authored-by: Yassin Kortam <yassin@berri.ai> * fix: restore unreachable InternalServerError skip handler in vertex test Co-authored-by: Yassin Kortam <yassin@berri.ai> * feat(mcp): add dedicated oauth_passthrough flag for non-oauth2 pass-through Previously is_oauth_passthrough reused delegate_auth_to_upstream — a flag scoped to oauth2 servers (PKCE bypass) — to gate OAuth pass-through for auth_type=none servers. Overloading it risked regressing existing deployments that set delegate_auth_to_upstream, since the same flag would silently start driving pass-through (discovery proxying, 401 challenges, upstream 401/403 propagation) on non-oauth2 servers. Introduce a separate oauth_passthrough opt-in so the two behaviors never imply each other: - MCPServer.is_oauth_passthrough now requires oauth_passthrough (not delegate_auth_to_upstream). - Persist oauth_passthrough on LiteLLM_MCPServerTable (new column + migration) and wire it through config/DB load and API responses. - UI splits the single toggle into two: "Delegate auth to upstream (PKCE passthrough)" for oauth2 and "OAuth pass-through" for auth_type=none servers forwarding Authorization. Adds backend tests (property, round-trip, and a regression guard that delegate_auth_to_upstream alone never enables pass-through) and UI tests for the toggle split. * fix(mcp): reconcile cold-start bypass with x-mcp-servers header and skip non-absolute WWW-Authenticate fabrication - _parse_mcp_server_names_from_path now fails closed when the x-mcp-servers header introduces any target not present in the path-derived target set, closing a header/path mismatch where the cold-start passthrough bypass could otherwise admit anonymously while the header advertises a non-passthrough server. - MCPUpstreamAuthError.to_http_exception no longer emits a relative resource_metadata URI when base_url is missing; per RFC 9728 3.2 the URI must be absolute, so we skip fabrication entirely rather than send a challenge strict MCP clients will reject. Co-authored-by: Yassin Kortam <yassin@berri.ai> * fix(mcp): fabricate path-aware resource_metadata URI for upstream 401 When MCPUpstreamAuthError.to_http_exception fabricates a `WWW-Authenticate: Bearer resource_metadata=...` challenge (because the upstream 401 omitted one), the URL now matches the inbound MCP transport pattern the client originally used: - /mcp/{server_name} -> /.well-known/oauth-protected-resource/mcp/{server_name} - /{server_name}/mcp -> /.well-known/oauth-protected-resource/{server_name}/mcp This mirrors the path-aware behaviour of _get_passthrough_resource_metadata_url in server.py so strict RFC 9728 \xA73.2 clients on legacy routes get a resource_metadata URI aligned with the resource pattern they originally targeted. Co-authored-by: Yassin Kortam <yassin@berri.ai> * fix(jwt+mcp): tighten issuer-scoped claim type handling, RFC-quote authorization_uri, surface MCP upstream auth errors, defense-in-depth on decode options - handle_jwt: when an issuer-scoped _litellm_team_ids claim exists but has an unexpected type, return [] instead of falling through to the global team_ids_jwt_field path (different claim semantically). - handle_jwt: _get_decode_options/_decode_jwt_with_public_key now take an explicit disable_audience_validation flag; passing audience=None without it raises, so audience checks can't silently disappear if the model validator is ever bypassed. _auth_jwt_with_issuer forwards the flag from JWTIssuerConfig. - mcp_server: quote the authorization_uri WWW-Authenticate parameter value (RFC 6750 / 9728 auth-param must be quoted-string), matching the pass-through path. - mcp_server: in _fetch_and_filter_server_tools, re-raise MCPUpstreamAuthError so the outer streamable-HTTP handler can surface a proper 401 + WWW-Authenticate challenge instead of returning an empty tool list. Co-authored-by: Yassin Kortam <yassin@berri.ai> * chore(docker): align Dockerfile.non_root/Dockerfile.database to current wolfi-base SHA The older sha256:3258be... pin has been intermittently returning 500/not-found from cgr.dev, breaking the test-server-root-path GitHub Action and the build_docker_database_image CircleCI job. Move both Dockerfiles onto the same sha256:31da65... digest already in use by Dockerfile, gateway/Dockerfile, backend/Dockerfile, and migrations/Dockerfile so the base image is consistent across the repo. * ci(docker): bump wolfi-base pin to current working digest The previously aligned sha256:31da6565f35a... and the older sha256:3258be... both return HTTP 500 from cgr.dev's manifest endpoint, breaking the build_docker_database_image CircleCI job and test-server-root-path GitHub Action. The current 'latest' tag resolves to sha256:5743937d521c... which serves manifests normally, so move docker/Dockerfile.database and docker/Dockerfile.non_root onto that digest. * ci(docker): retry apk add in Dockerfile.database for apk.cgr.dev flakes Mirror the retry-loop pattern from #28888 (which fixed backend/Dockerfile, gateway/Dockerfile, and migrations/Dockerfile) into docker/Dockerfile.database. The build_docker_database_image CI job has been intermittently failing with "remote server returned error (try 'apk update')" when apk.cgr.dev flakes mid-fetch; bumping the wolfi-base SHA doesn't address the mirror, only a retry does. Same explicit-failure form as #28888: exit non-zero on the 3rd miss instead of silently succeeding because `sleep 5` was the last command in the `&& break || sleep 5` chain. * fix(mcp): scope preemptive 401 to toolset-narrowed server set Move _raise_preemptive_401_for_unauthenticated_servers after toolset scoping in both the StreamableHTTP and SSE handlers, and add an optional allowed_server_ids parameter so passthrough/oauth2 servers that the active toolset excludes no longer trigger a spurious 401 challenge. Without this, a client targeting a toolset whose scope excludes a passthrough server could be pushed into an OAuth flow for a server it would be 403'd on immediately after authentication.
