[release/13.4] Filter resources with resource.excludeFromMcp from CLI MCP tools#18150
Merged
Conversation
Resources marked with the resource.excludeFromMcp property are now excluded from all MCP tool results: - ListResourcesTool filters them from resource listings - ListConsoleLogsTool and ExecuteResourceCommandTool reject requests targeting excluded resources - ListStructuredLogsTool, ListTracesTool, and ListTraceStructuredLogsTool filter out telemetry from excluded resources - McpResourceToolRefreshService skips excluded resources Added McpToolHelpers with IsExcludedFromMcp, CheckResourceExcludedAsync, GetExcludedResourceNamesAsync, and GetResourceNotAvailableMessage helpers. Includes comprehensive unit tests covering all filtering scenarios.
- Add two tests for ListTraceStructuredLogsTool filtering:
- FiltersExcludedResourceLogs: verifies excluded resource logs are
removed from trace-scoped structured log results
- ReturnsAllLogs_WhenNoResourcesExcluded: verifies no filtering when
no resources are excluded
- Add doesNotContainMarker parameter to CallAgentMcpToolAsync helper
- Add AgentMcpExcludeFromMcpTests E2E test that verifies list_resources
excludes resources marked with ExcludeFromMcp()
Add overloads of CheckResourceExcludedAsync and GetExcludedResourceNamesAsync that accept IAppHostAuxiliaryBackchannel directly. Update ListConsoleLogsTool and ExecuteResourceCommandTool to use the connection they already obtained, eliminating a redundant GetSelectedConnectionAsync + GetResourceSnapshotsAsync call per request.
The test was timing out because the Redis container's health check never passed in the Docker-in-Docker CI environment, causing webfrontend (which has WaitFor(cache)) to stay stuck in Waiting state. Redis is irrelevant to this test — it only verifies ExcludeFromMcp() filtering. Disabling Redis removes the container dependency.

Updated [Aspire.Hosting.PostgreSQL](https://github.com/microsoft/aspire) from 13.3.5 to 13.4.6. <details> <summary>Release notes</summary> _Sourced from [Aspire.Hosting.PostgreSQL's releases](https://github.com/microsoft/aspire/releases)._ ## 13.4.6 ## What's New in Aspire 13.4.6 Patch release for Aspire 13.4 fixing polyglot AppHost code generation binding when CLI and SDK versions diverge, resource service port collision in `--isolated` mode, and a MongoDB.Driver dependency update. ### 🐛 Fixes - 🔗 **Polyglot AppHost code generation silently failed when CLI and SDK versions diverged** — `Aspire.TypeSystem` used a floating strong-name `AssemblyVersion` that changed with every build. When the installed Aspire CLI was built at a different version than the AppHost's SDK, the CLR couldn't satisfy the strong-name bind and every code generator (TypeScript, Python, Java, Go, Rust) was silently dropped, surfacing as `No code generator found for language: <lang>`. The `AssemblyVersion` is now frozen at a stable constant so any compatible CLI/SDK pair on 13.4 binds successfully. Relates to #18110 and #17910. ([#18160](microsoft/aspire#18160), `@sebastienros`) - 🔌 **Multiple AppHosts started with `--isolated` collided on the resource service port** — Both instances tried to bind to the same fixed port from `ASPIRE_RESOURCE_SERVICE_ENDPOINT_URL`, causing an "address already in use" error on the second instance. `DashboardServiceHost` now binds to port 0 on loopback when `RandomizePorts` is true (set by `--isolated`), letting the OS assign a unique port per instance. ([#18341](microsoft/aspire#18341), `@JamesNK`) - 🍃 **MongoDB.Driver updated to 3.9.0** — Removes a wrongly pinned `SharpCompress` transitive dependency and uses the corrected `Snappier` transitive. Fixes #17981. ([#18279](microsoft/aspire#18279), `@Falco20019`) ### 🏷️ Housekeeping - 🚀 Bumped branding to 13.4.6 ([#18343](microsoft/aspire#18343)) --- _Full Changelog: [v13.4.5...v13.4.6](microsoft/aspire@v13.4.5...v13.4.6)_ _Full commit: [87fe259e4fc244c599019a7b1304c85a1488f248](microsoft/aspire@87fe259e4fc244c599019a7b1304c85a1488f248)_ > Generated by [Generate release notes for a new stable Aspire release](https://github.com/microsoft/aspire/actions/runs/27855270514) · 131 AIC · ⌖ 13.5 AIC · ⊞ 37.4K <!-- gh-aw-agentic-workflow: Generate release notes for a new stable Aspire release, engine: copilot, version: 1.0.60, model: claude-sonnet-4.6, id: 27855270514, workflow_id: release-notes-generate, run: https://github.com/microsoft/aspire/actions/runs/27855270514 --> ## 13.4.5 ## What's New in Aspire 13.4.5 Patch release for Aspire 13.4 clearing a transitive MessagePack security advisory, tightening CLI validation for Playwright configuration, and adding coding-agent detection to CLI telemetry. ### 🐛 Fixes - 🛡️ **Bumped StreamJsonRpc to 2.25.29 to clear the MessagePack GHSA-hv8m-jj95-wg3x (CVE-2026-48109) NU1903 advisory** — The transitive MessagePack 2.5.192 dependency pulled in via StreamJsonRpc 2.22.23 fell within the advisory's vulnerable LZ4 decompression range. Aspire does not use `MessagePackFormatter` or LZ4 — all StreamJsonRpc calls use `SystemTextJsonFormatter` over local Unix sockets — so the vulnerability was not reachable in practice. The bump clears the NU1903 warning for consumers of the `Aspire.Hosting` package. ([#18204](microsoft/aspire#18204), `@mitchdenny`) - 🎭 **`playwrightCliVersion` values that are not valid SemVer 2.0 now fail fast with a clear diagnostic** — Previously an invalid override (range expression, dist-tag like `latest`, or a `v`-prefixed string) would surface as a generic npm resolution failure. The value is now validated with strict SemVer parsing at startup; an error naming the configuration key and the offending value is emitted immediately. ([#18205](microsoft/aspire#18205), `@mitchdenny`) - 🤖 **CLI telemetry now detects and reports the calling coding agent** — When the Aspire CLI is invoked from inside a known coding agent environment (GitHub Copilot CLI, VS Code Copilot agent, etc.) the agent name is included in the main CLI telemetry event. GitHub Copilot CLI is specifically identified as `copilot-cli`. ([#18240](microsoft/aspire#18240), `@damianedwards`) ### 🏷️ Housekeeping - 📄 Refreshed the `@microsoft/aspire-cli` npm package README to be TypeScript-only — updated examples to the current `ts-starter` template (`apphost.mts` / `aspire.mjs`), added a backing-services snippet showing `aspire add` for PostgreSQL and Redis, and documented `aspire dashboard run` as a standalone dashboard option.

Reconnection is now attempted as part of the DCP request retry path so transient disconnections recover automatically without surfacing errors. ([#18096](microsoft/aspire#18096), `@karolz-ms`) * 🔍 **Resources marked with `ExcludeFromMcp()` were not consistently filtered from CLI MCP tools** — Resources with the `resource.excludeFromMcp` property were not excluded uniformly from all CLI MCP tool results. `list_resources`, `list_console_logs`, `execute_resource_command`, `list_structured_logs`, `list_traces`, and `list_trace_structured_logs` all now honor the exclusion, preventing excluded resources and their telemetry from appearing in agent context.

This caused integrations that depend on endpoint allocation before resource startup (such as the KeyVault emulator) to fail. Persistent containers now default to proxied endpoints matching normal container behavior; opt out with `isProxied: false` or `WithEndpointProxySupport(false)`. Proxyless container endpoints with only a `targetPort` specified now also resolve immediately to that port instead of waiting for delayed allocation.

When the public port differed from the target port (or was not yet allocated) the container would listen on an unexpected port and become unreachable.

This meant user-interaction callbacks such as `WithEnvironment(ctx => PromptForValueAsync(...))` were called before the user triggered the resource. DCP registration is now deferred until the user manually starts the resource; persistent explicit-start resources still register immediately but patch the existing DCP record to `Start = true` rather than deleting and recreating it. Fixes #17813. (#17825, backported via #17826, `@danegsta`) - 🔴 **Redis with `WithLifetime(ContainerLifetime.Persistent)` could deadlock on startup** — Redis TLS startup arguments used the public/allocated host ports instead of the internal target ports. When the public port differed from the target port (or was not yet allocated) the container would listen on an unexpected port and become unreachable. The TLS and non-TLS startup arguments now bind to target ports, matching what Redis expects internally. Fixes #17822. (#17827, backported via #17850, `@danegsta`) - 🔌 **Proxyless container endpoint could hang when resolved before container creation** — Referencing a proxyless container endpoint in an environment variable callback (before the container port spec was finalized) could deadlock. An on-demand allocation path now commits the target port as the fallback host port in that case; once `BuildContainerPorts` runs, normal DCP dynamic port assignment takes over for any later resolution. (#17851, backported via #17859, `@danegsta`) - 📄 **Empty C# AppHost template emitted duplicate `profiles` block** — `aspire new aspire-empty` on 13.4 produced an `aspire.config.json` with a `profiles` block that duplicated the content already present in `apphost.run.json`, causing redundant launch configuration. The embedded template now contains only the required `appHost.path` binding; profile configuration lives exclusively in `apphost.run.json`. Fixes #17660. (#17781, backported via #17820, `@mitchdenny`) ### 🏷️ Housekeeping - 📦 Added Aspire CLI npm package to the release pipeline so the npm distribution is published as part of stable releases.

As part of GA, the experimental markers on the Azure TypeScript AppHost (ATS) APIs have been removed and the ATS surface area is stable for 13.4. - 🤖 **Foundry hosted agents** — Protocol selection (`responses` / `invocations`) is now configurable from both C# and TypeScript AppHosts. Cross-compute-environment deployments (e.g., a Foundry hosted agent + an AKS consumer) now wire up correctly: endpoint resolution and the required **Azure AI User** RBAC role assignment on the Foundry account are generated automatically — no manual `az role assignment create` steps needed. - 🛠️ **Aspire skills catalog from bundle** — `aspire agent init` now drives its installable skill catalog from the bundle manifest, surfacing all six bundled skills (previously only three were visible). An embedded snapshot means the full catalog is available even in airgapped / disconnected environments. - 🔧 **CLI reliability** — Multiple CLI fixes: implicit-channel discovery restored, `aspire stop` no longer falsely reports failure on Unix, `aspire ps` no longer includes raw resource data (use `aspire describe` for detailed state), `aspire new` prefers the current CLI template version, friendly error for `aspire do --list-steps` without a step argument, and improved `--search` option description with documentation link. - ⌨️ **TypeScript AppHost** — Fixed a deadlock that occurred when lazy options callbacks invoked async methods; dev-localhost resource service URLs are now accepted for local development without extra configuration. - 📊 **Dashboard** — Summary log formatting improved for readability, `dotnet watch` dashboard auto-launch signal restored, and dynamic-port handling fixed for `DistributedApplicationTestingBuilder`. - ☸️ **Kubernetes** — The Helm CLI minimum version (≥ 4.2.0) is now validated before a Kubernetes deploy, giving a clear error instead of a cryptic failure. -⚠️ **`Aspire.Hosting.Blazor` ships as preview in 13.4** — A packaging issue with the Blazor gateway scripts means the package is intentionally marked preview for this release. Full stable support is targeted for 13.5. ##⚠️ Notable changes - `aspire ps` no longer includes raw resource data in its output. Use `aspire describe <resource>` to inspect detailed resource state. - Foundry hosted agent builder API shape updated — see [#17545](microsoft/aspire#17545) and [#17669](microsoft/aspire#17669) for the updated C# and TypeScript signatures. - `Aspire.Hosting.Blazor` is preview-versioned in 13.4 (`SuppressFinalPackageVersion=true`). A fix for the `addBlazorGateway` gateway script resolution error in TypeScript AppHosts is tracked in [#17685](microsoft/aspire#17685). ## 📖 Learn more For the full details on everything in this release, check out the [What's new in Aspire 13.4](https://aspire.dev/whats-new/aspire-13-4/) documentation.

Reconnection is now attempted as part of the DCP request retry path so transient disconnections recover automatically without surfacing errors. ([#18096](microsoft/aspire#18096), `@karolz-ms`) * 🔍 **Resources marked with `ExcludeFromMcp()` were not consistently filtered from CLI MCP tools** — Resources with the `resource.excludeFromMcp` property were not excluded uniformly from all CLI MCP tool results. `list_resources`, `list_console_logs`, `execute_resource_command`, `list_structured_logs`, `list_traces`, and `list_trace_structured_logs` all now honor the exclusion, preventing excluded resources and their telemetry from appearing in agent context.

This caused integrations that depend on endpoint allocation before resource startup (such as the KeyVault emulator) to fail. Persistent containers now default to proxied endpoints matching normal container behavior; opt out with `isProxied: false` or `WithEndpointProxySupport(false)`. Proxyless container endpoints with only a `targetPort` specified now also resolve immediately to that port instead of waiting for delayed allocation.

When the public port differed from the target port (or was not yet allocated) the container would listen on an unexpected port and become unreachable.

This meant user-interaction callbacks such as `WithEnvironment(ctx => PromptForValueAsync(...))` were called before the user triggered the resource. DCP registration is now deferred until the user manually starts the resource; persistent explicit-start resources still register immediately but patch the existing DCP record to `Start = true` rather than deleting and recreating it. Fixes #17813. (#17825, backported via #17826, `@danegsta`) - 🔴 **Redis with `WithLifetime(ContainerLifetime.Persistent)` could deadlock on startup** — Redis TLS startup arguments used the public/allocated host ports instead of the internal target ports. When the public port differed from the target port (or was not yet allocated) the container would listen on an unexpected port and become unreachable. The TLS and non-TLS startup arguments now bind to target ports, matching what Redis expects internally. Fixes #17822. (#17827, backported via #17850, `@danegsta`) - 🔌 **Proxyless container endpoint could hang when resolved before container creation** — Referencing a proxyless container endpoint in an environment variable callback (before the container port spec was finalized) could deadlock. An on-demand allocation path now commits the target port as the fallback host port in that case; once `BuildContainerPorts` runs, normal DCP dynamic port assignment takes over for any later resolution. (#17851, backported via #17859, `@danegsta`) - 📄 **Empty C# AppHost template emitted duplicate `profiles` block** — `aspire new aspire-empty` on 13.4 produced an `aspire.config.json` with a `profiles` block that duplicated the content already present in `apphost.run.json`, causing redundant launch configuration. The embedded template now contains only the required `appHost.path` binding; profile configuration lives exclusively in `apphost.run.json`. Fixes #17660.

As part of GA, the experimental markers on the Azure TypeScript AppHost (ATS) APIs have been removed and the ATS surface area is stable for 13.4. - 🤖 **Foundry hosted agents** — Protocol selection (`responses` / `invocations`) is now configurable from both C# and TypeScript AppHosts. Cross-compute-environment deployments (e.g., a Foundry hosted agent + an AKS consumer) now wire up correctly: endpoint resolution and the required **Azure AI User** RBAC role assignment on the Foundry account are generated automatically — no manual `az role assignment create` steps needed. - 🛠️ **Aspire skills catalog from bundle** — `aspire agent init` now drives its installable skill catalog from the bundle manifest, surfacing all six bundled skills (previously only three were visible). An embedded snapshot means the full catalog is available even in airgapped / disconnected environments. - 🔧 **CLI reliability** — Multiple CLI fixes: implicit-channel discovery restored, `aspire stop` no longer falsely reports failure on Unix, `aspire ps` no longer includes raw resource data (use `aspire describe` for detailed state), `aspire new` prefers the current CLI template version, friendly error for `aspire do --list-steps` without a step argument, and improved `--search` option description with documentation link. - ⌨️ **TypeScript AppHost** — Fixed a deadlock that occurred when lazy options callbacks invoked async methods; dev-localhost resource service URLs are now accepted for local development without extra configuration. - 📊 **Dashboard** — Summary log formatting improved for readability, `dotnet watch` dashboard auto-launch signal restored, and dynamic-port handling fixed for `DistributedApplicationTestingBuilder`. - ☸️ **Kubernetes** — The Helm CLI minimum version (≥ 4.2.0) is now validated before a Kubernetes deploy, giving a clear error instead of a cryptic failure. -⚠️ **`Aspire.Hosting.Blazor` ships as preview in 13.4** — A packaging issue with the Blazor gateway scripts means the package is intentionally marked preview for this release. Full stable support is targeted for 13.5. ##⚠️ Notable changes - `aspire ps` no longer includes raw resource data in its output. Use `aspire describe <resource>` to inspect detailed resource state. - Foundry hosted agent builder API shape updated — see [#17545](microsoft/aspire#17545) and [#17669](microsoft/aspire#17669) for the updated C# and TypeScript signatures. - `Aspire.Hosting.Blazor` is preview-versioned in 13.4 (`SuppressFinalPackageVersion=true`). A fix for the `addBlazorGateway` gateway script resolution error in TypeScript AppHosts is tracked in [#17685](microsoft/aspire#17685). ## 📖 Learn more For the full details on everything in this release, check out the [What's new in Aspire 13.4](https://aspire.dev/whats-new/aspire-13-4/) documentation.

Customer Impact
ExcludeFromMcp()no longer works. A customer would use it with a resource and expect the resource to be excluded from MCP calls. However the annotation doesn't work. The resource data is available from MCP and its tools are callable from MCP.Testing
