After you create the app and add its credentials, rerun the waited deployment to write `.mda/slack/app-manifest.json` with the deployed Events URL. For the complete workflow, see [Slack channels](/langsmith/managed-deep-agents-channels-slack#create-and-deploy-the-slack-app). -Only a project-root `agent.ts`, `agent.tsx`, or `agent.py` is required. The CLI detects the first available entry in that order. - -### Agent entry - -The agent entry must export a named `agent` definition created with `define_deep_agent` or `defineDeepAgent`. For a minimal example, see the [quickstart](/langsmith/managed-deep-agents-quickstart#edit-the-agent). - -The definition accepts the Deep Agents `createDeepAgent` configuration surface except managed keys. Setting a managed key is an error. - -### Authored tools and middleware - -Put project-owned tools and middleware in local modules such as `tools/` and `middleware/`, import them from the agent entry, and pass them through the `tools` and `middleware` fields. The CLI copies those files into the compiled build without rewriting them. - -For examples, see [Custom tools](/langsmith/managed-deep-agents-tools) and [Custom middleware](/langsmith/managed-deep-agents-middleware). - -### Identity - -Optionally export a named `identity` declaration from a project-root `identity.ts` or `identity.py` created with `defineIdentity` / `define_identity` (or `.preset(...)`). - -When present, `mda` generates the custom auth handler, injects it into the compiled app, and scopes threads, memory, and store access from the declaration. Projects without identity keep the previous compile output. For presets, ingress modes, guest tokens, and `runtime.identity`, see [Identity](/langsmith/managed-deep-agents-identity). - -### Instructions - -Put the system prompt in `instructions.md` next to the project-root agent entry file. - -`mda dev` embeds the prompt in the generated entry. `mda deploy` syncs the prompt to Context Hub and the deployed runtime reads it from there. - -### Skills - -Put deploy-owned skills under `skills/` next to the project-root agent entry file. Deploy syncs every UTF-8 file under `skills/**` into Context Hub and deletes stale deployed skills that no longer exist locally. - -### Memory - -Managed memory lives in the same Context Hub repo as the deployed instructions and skills. The runtime remounts a scoped tree as `/memories/user/` (hot `/memories/user/AGENTS.md` plus optional cold files) and optional org facts as `/memories/org/` (read-only). Deploy seeds agent memory when needed and syncs `instructions.md` and `skills/**`, but does not overwrite existing Context Hub `memories/**` files. For hot/cold tiers, identity remounts, org memory, and `disableMemory`, see [Memory](/langsmith/managed-deep-agents-memory). - -### Connectors - -Declare connectors as modules directly under `connectors/`. Discovery is name-agnostic: each file is a connector module (package `__init__.py` files are ignored). - -- **MCP:** `connectors/mcp.ts` or `connectors/mcp.py` must export a named `mcp` declaration. Supports remote `http` and `sse` servers; stdio is rejected. When present, `mda` injects `@langchain/mcp-adapters` or `langchain-mcp-adapters` and appends loaded MCP tools to authored tools. -- **GitHub:** `connectors/github.ts` or `connectors/github.py` declares repository checkouts, GitHub CLI installation, and credential injection for the managed sandbox. -- **LangSmith:** `connectors/langsmith.ts` or `connectors/langsmith.py` declares constrained LangSmith capabilities for untrusted callers. Requires [identity](/langsmith/managed-deep-agents-identity). The browser never receives `LANGSMITH_API_KEY`. - -For examples and defaults, see [Connectors](/langsmith/managed-deep-agents-connectors). - -### Channels - -Declare messaging channels as modules directly under `channels/`. Each file exports a named `channel` (for example `defineSlackChannel` / `defineGitHubChannel`). The file stem becomes the channel name and mounts `POST /channels/{name}/events` on the Agent Server. Channels require a root [identity](/langsmith/managed-deep-agents-identity) declaration. - -- **Slack:** `channels/slack.ts` or `channels/slack.py`. Deploy preflights `SLACK_SIGNING_SECRET` and `SLACK_BOT_TOKEN` (from the channel manifest `requiredEnv`). -- **GitHub:** `channels/github.ts` or `channels/github.py` with ordered `handlers` (`on`, `prompt`, optional `repositories` / `autoReply`). Deploy preflights `GITHUB_WEBHOOK_SECRET`, `GITHUB_APP_ID`, `GITHUB_APP_PRIVATE_KEY`, and `GITHUB_INSTALLATION_ID`. - -For handlers, triggers, and provider setup, see [Channels](/langsmith/managed-deep-agents-channels), [Slack](/langsmith/managed-deep-agents-channels/slack), and [GitHub](/langsmith/managed-deep-agents-channels/github). - -### Schedules - -Declare managed cron schedules under `schedules/`. Each direct child schedule file must export a named `schedule` declaration from `defineSchedule(...)` or `define_schedule(...)`. - -Deploy extracts schedule declarations from static literals, arrays, objects, and top-level literal constants. A schedule can deliver its final response to a configured Slack channel with `deliver_to` / `deliverTo`. After the deployment reaches `DEPLOYED`, `mda deploy` replaces the existing managed LangSmith cron jobs with the current local schedule declarations. For examples and constraints, see [Schedules](/langsmith/managed-deep-agents-schedules). - -### Sandbox - -To configure a managed sandbox, export `sandbox` from `sandbox/index.ts` for TypeScript or `sandbox/__init__.py` for Python. Scope defaults to one sandbox per thread; `scope: "agent"` shares one across the agent process. `sandbox/setup.sh`, when present, runs once when a new managed sandbox is provisioned. +On success, the CLI prints the LangSmith deployment dashboard URL. For secrets routing and deploy tips, see [Deploy an agent](/langsmith/managed-deep-agents-deploy). -For configuration examples and lifecycle behavior, see [Configure a sandbox](/langsmith/managed-deep-agents-deploy#configure-a-sandbox). +## Read deployment logs -### Evals +Use `mda logs` to tail Agent Server logs for a deployed agent: -Put Harbor-style eval tasks under `evals/`. Each task directory includes `instruction.md`, `task.toml`, an `environment/` image, and a `tests/test.sh` verifier. When the project declares [identity](/langsmith/managed-deep-agents-identity), each task also needs `identity.json`. +```bash +mda logs . +``` -`mda init` scaffolds starter evals under `evals/`. For existing projects, use `mda evals init`. Compile a Harbor handoff with `mda evals compile`, then run trials with Harbor. Artifacts land under `.mda/evals/` and are not part of the deploy archive.

Durable memory persists in [Context Hub](#context-hub) and is available to the agent across threads. - -When you declare [identity](/langsmith/managed-deep-agents-identity), Managed Deep Agents scopes threads and remounts the matching memory slice for the authenticated actor or tenant so callers cannot open each other's conversations or memory. Without identity, the deployment uses shared agent memory. - -Scheduled runs choose their thread behavior explicitly. An ephemeral thread is cleaned up after the run, while a persistent thread reuses a stable thread ID so state accumulates. For the thread modes and when to use each, see [Schedules](/langsmith/managed-deep-agents-schedules). - -## Sandboxes - -A [sandbox](/langsmith/sandboxes) gives the agent an isolated environment for code execution and filesystem work. Configure one by exporting `sandbox` from `sandbox/index.ts` or `sandbox/__init__.py`, and use `sandbox/setup.sh` to provision it the first time it is created. Sandboxes default to one per thread; set `scope` to `agent` to share one across the agent process. Connectors can also provision files, CLIs, and credentials when a sandbox starts. For configuration options and examples, see [Configure a sandbox](/langsmith/managed-deep-agents-deploy#configure-a-sandbox). - -## Connectors - -Optional modules directly under `connectors/` extend the agent with external tools and capabilities. Discovery is name-agnostic: each file is a connector, and you do not register connectors in the agent entry. The runtime loads each connector when it compiles and starts the deployment: - -- **MCP** (`connectors/mcp.{py,ts}`): the runtime creates the MCP client, loads tools from the declared remote servers, and appends them to the authored tools at runtime. -- **LangSmith** (`connectors/langsmith.{py,ts}`): the runtime mounts one HTTP route per capability on the Agent Server and runs each call server-side with the workspace key, so untrusted callers never receive `LANGSMITH_API_KEY`. Requires a root identity declaration. -- **GitHub** (`connectors/github.{py,ts}`): when the project declares a sandbox, the runtime clones the configured repositories, installs the `gh` CLI, and injects credentials as the sandbox starts. - -For authoring, defaults, and provider setup, see [Connectors](/langsmith/managed-deep-agents-connectors). - -## Channels - -Optional modules under `channels/` mount public provider Events URLs on the Agent Server (for example Slack at `POST /channels/slack/events`, or GitHub at `POST /channels/github/events`).

Bob opens a new chat and the agent already "knows" Alice's details. | -| **Shared threads** | Anyone who can hit the deployment can resume or inspect another user's conversation. | -| **Wrong credentials** | The agent calls GitHub or another API with one shared token, so every user acts as the same account, or you have no safe way to act *as* the signed-in user. | - -Deep Agents without identity make this a real problem: they keep durable memory, resume long-running threads, and call tools on the user's behalf. Identity turns "who is calling?" into enforced isolation instead of hoping the prompt or the UI keeps people apart. - -A key benefit of identity is that downstream tool calls can act **as the signed-in user** rather than as a shared bot account. For example, with `credentials: "actor"`, the agent calls GitHub as Alice, not as a single bot token shared across all users. - -For deployments with compliance requirements such as SOC 2, GDPR, or HIPAA, identity scoping provides the data segregation boundaries that auditors expect: each caller's threads and memory are isolated, and `runtime.identity` gives you an audit trail of who triggered each run. - - -Adding identity to a project that previously had none does not delete existing threads or memory. Threads created before identity was enabled remain accessible at the agent scope. New threads are scoped by actor (or tenant) according to your declaration.

For the broader LangGraph auth model, see [Add auth to your server](/langsmith/add-auth-server). - -Required headers (case-insensitive): +Pass `url` instead of the project reference for a custom auth domain. -| Header | Required | Purpose | -| --- | --- | --- | -| `X-MDA-Ingress-Secret` | Yes | Shared secret from `MDA_INGRESS_SECRET` | -| `X-MDA-Actor-Id` | Yes | Actor id for this run | -| `X-MDA-Tenant-Id` | When `tenancy: "multi"` | Tenant id for this run | +4. In the client app, set the Supabase project URL and publishable (anon) key. Sign the user in, then send the access token on every deployment request: -Use a preset that defaults to trusted-backend ingress: +:::python +```python +import httpx - - -```python identity.py -from managed_deepagents import define_identity - -identity = define_identity.preset("internal-tool") -``` - -```ts identity.ts -import { defineIdentity } from "managed-deepagents"; - -export const identity = defineIdentity.preset("internal-tool"); +response = httpx.post( + f"{deployment_url}/threads/{thread_id}/runs", + headers={ + "Authorization": f"Bearer {supabase_access_token}", + "Content-Type": "application/json", + }, + json=run_body, +) ``` +::: - - -Put `MDA_INGRESS_SECRET` in `.env` for `mda dev` and as a hosted deployment secret for `mda deploy`. In production, your backend authenticates the user, then attaches the identity headers (`X-MDA-Ingress-Secret`, `X-MDA-Actor-Id`, and `X-MDA-Tenant-Id` when applicable) when proxying agent traffic. - -Example shape for a backend proxy (pseudocode): - +:::js ```ts -// After your app authenticates the user await fetch(`${deploymentUrl}/threads/${threadId}/runs`, { method: "POST", headers: { + Authorization: `Bearer ${supabaseAccessToken}`, "Content-Type": "application/json", - "X-MDA-Ingress-Secret": process.env.MDA_INGRESS_SECRET!, - "X-MDA-Actor-Id": authenticatedUser.id, - // "X-MDA-Tenant-Id": org.id, // only when tenancy is "multi" }, body: JSON.stringify(runBody), }); ``` +::: - -Never commit ingress secrets or IdP credentials. Only send `MDA_INGRESS_SECRET` from a trusted backend proxy, never from the browser. - - -### Validated token (browser-direct) - -Use this when the browser talks to the deployment directly and you do not want a proxy that asserts actor headers. - -The client sends `Authorization: Bearer `. Managed Deep Agents verifies the token server-side and maps claims (fields inside the token, such as user id) into `runtime.identity`. - -Verification can use: - -- **JWKS**: public keys your IdP publishes so the runtime can verify signed JWTs -- **OIDC discovery**: standard metadata that points the runtime at those keys -- **Opaque introspection**: call the IdP to ask whether a non-JWT token is still valid -- **Guest tokens**: short-lived tokens signed by Managed Deep Agents for anonymous visitors - -Override a preset to enable validated-token ingress. The following example combines Supabase sign-in with optional guest access: - - - -```python identity.py -from managed_deepagents import define_identity, providers - -identity = define_identity.preset( - "internal-tool", - { - "ingress": { - "http": { - "mode": "validated_token", - "providers": [ - providers.supabase(project_ref="your-project-ref"), - providers.guest(ttl="24h", actor_prefix="guest:"), - ], - } - } - }, -) -``` - -```ts identity.ts -import { defineIdentity, providers } from "managed-deepagents"; - -export const identity = defineIdentity.preset("internal-tool", { - ingress: { - http: { - mode: "validated_token", - providers: [ - providers.supabase({ projectRef: "your-project-ref" }), - providers.guest({ ttl: "24h", actorPrefix: "guest:" }), - ], - }, - }, -}); -``` - - - -In `validated_token` mode, your frontend signs the user in with the same IdP you configured, reads an access token (or ID token where applicable), and passes it to the LangGraph client as `Authorization: Bearer `. Do not send refresh tokens or client secrets to the deployment. - -When you configure more than one provider, give each entry a unique `id`. The runtime routes JWT providers by token `iss` (issuer) and returns 401 when the issuer does not match any configured provider. - -For provider-specific options and client examples, see [Provider setup guides](#provider-setup-guides). - -To let anonymous visitors use the agent with no external identity provider, configure guest tokens as the only provider. Each visitor gets a short-lived, Managed Deep Agents-signed token and a distinct guest actor, so the `private-assistant` preset still scopes threads and memory per visitor. +The publishable (anon) key is only for the client to sign in with Supabase. Do not send a LangSmith API key in this mode. The Bearer token is the caller identity. - - -```python identity.py -from managed_deepagents import define_identity, providers - -identity = define_identity.preset( - "private-assistant", - { - "ingress": { - "http": { - "mode": "validated_token", - "providers": [ - providers.guest(ttl="24h", actor_prefix="guest:"), - ], - } - } - }, -) -``` - -```ts identity.ts -import { defineIdentity, providers } from "managed-deepagents"; - -export const identity = defineIdentity.preset("private-assistant", { - ingress: { - http: { - mode: "validated_token", - providers: [providers.guest({ ttl: "24h", actorPrefix: "guest:" })], - }, - }, -}); -``` - - - -When a guest provider is configured, the deployment exposes a public `POST /identity/guest` route that mints a guest token. The client calls it once, then sends the returned token as `Authorization: Bearer ` on later requests. The response body is `{"token": ""}`. - -```bash -USER_TOKEN=$(curl -s -X POST "$DEPLOYMENT_URL/identity/guest" \ - -H "Content-Type: application/json" | python -c 'import sys, json; print(json.load(sys.stdin)["token"])') -``` - -## Secrets checklist - -| Secret | How Managed Deep Agents uses it | -| --- | --- | -| `MDA_INGRESS_SECRET` | Shared secret your backend sends in `X-MDA-Ingress-Secret`. The runtime checks it before trusting `X-MDA-Actor-Id` and `X-MDA-Tenant-Id`. | -| `MDA_GUEST_SIGNING_KEY` | Key used to sign guest tokens at `POST /identity/guest` and to verify them on later requests. | - -Put local values in `.env`. `mda deploy` forwards non-reserved `.env` values as hosted deployment secrets. Provider-specific secrets (for example Supabase introspection) are listed in [Provider setup guides](#provider-setup-guides). - - -Never commit ingress secrets, guest signing keys, or IdP credentials. Only send `MDA_INGRESS_SECRET` from a trusted backend proxy, never from the browser. - - -## Use `runtime.identity` in tools and middleware - -When identity is declared, authored tools and middleware receive a frozen `runtime.identity` object built from the trusted auth result. Client-supplied spoofable identity keys are stripped from `configurable`. - -The identity object looks like this: - -```ts -runtime.identity = { - actor: { type: "user" | "service", id: string, email?: string }, - tenant?: { id: string }, - source: { - provider: "http" | "slack" | "schedule" | "cli" | "studio", - threadId?: string, - }, - claims?: Record, // populated for validated_token ingress -}; -``` - -Annotate the injected `runtime` parameter as `ManagedDeepAgentRuntime` so you get typed access to `identity` (and optional `credentials`). Use it whenever a tool or middleware hook needs to know *who* triggered the run, for personalization, audit logs, or branching on verified claims, without trusting anything from the request body. - - - -```python tools/whoami.py -from langchain.tools import tool -from managed_deepagents import ManagedDeepAgentRuntime - - -@tool -def whoami(runtime: ManagedDeepAgentRuntime) -> str: - """Return the authenticated actor id for this run.""" - identity = runtime.identity - if not identity: - return "No authenticated caller on this run." - return f"Signed in as {identity['actor']['id']}" -``` - -```ts tools/whoami.ts -import { z } from "zod"; -import { tool } from "langchain"; -import type { ManagedDeepAgentRuntime } from "managed-deepagents"; - -export const whoami = tool( - async (_input, runtime: ManagedDeepAgentRuntime) => { - const identity = runtime.identity; - if (!identity) { - return "No authenticated caller on this run."; - } - return `Signed in as ${identity.actor.id}`; - }, - { - name: "whoami", - description: "Return the authenticated actor id for this run.", - schema: z.object({}), - }, -); -``` - - - -The same type works in middleware hooks: - - - -```python middleware/audit.py -from langchain.agents.middleware import AgentState, before_model -from managed_deepagents import ManagedDeepAgentRuntime - - -def audit_middleware(): - @before_model - def audit(state: AgentState, runtime: ManagedDeepAgentRuntime) -> dict | None: - user = runtime.identity["actor"]["id"] if runtime.identity else "anonymous" - print(f"[audit] {user} model call with {len(state['messages'])} messages") - return None - - return audit -``` - -```ts middleware/audit.ts -import { createMiddleware } from "langchain"; -import type { ManagedDeepAgentRuntime } from "managed-deepagents"; - -export function auditMiddleware() { - return createMiddleware({ - name: "audit", - beforeModel: (state, runtime: ManagedDeepAgentRuntime) => { - const user = runtime.identity?.actor.id ??

For other per-run values such as feature flags, use normal LangChain runtime context. - -## Customize scoping - -Presets cover the common cases. To customize, set `scoping` explicitly: - -| Axis | Values | Meaning | -| --- | --- | --- | -| `threads` | `actor`, `channel`, `tenant` | Who can open or resume the conversation | -| `memory` | `actor`, `tenant`, `agent`, `none` | Which Context Hub memory slice is remounted for the run | -| `credentials` | `agent`, `actor`, `none`, `custom` | Whose credentials downstream calls use | - -If `tenancy` is `"single"`, do not set any scoping axis to `"tenant"`, there is no tenant to scope by. If a request is missing the actor or tenant id that scoping needs, Managed Deep Agents rejects it with 403 instead of falling back to shared data. - -For how memory paths remount under each scope, see [Scope memory with identity](/langsmith/managed-deep-agents-memory#scope-memory-with-identity). - -### Custom downstream credentials - -Use `scoping.credentials: "custom"` when your application can securely obtain a per-actor credential for a downstream target. Provide a `resolve` function; tools then call `runtime.credentials.for(target)` to obtain the headers for that request. Resolved credentials are kept in memory and are never written to thread state or traces. +Managed Deep Agents verifies the JWT against the project's JWKS URL derived from your project reference (`https://.supabase.co/auth/v1/.well-known/jwks.json`). -The token that proves a caller's identity is not automatically a credential for downstream APIs. For example, a Supabase access token lets Managed Deep Agents identify the caller, but it is not a GitHub API token. Your backend or credential service must hold (and, when needed, refresh) the caller's separately authorized GitHub credential. +Adding Supabase identity to an existing deployment does not add owner metadata to existing threads. Plan and test a migration before relying on identity-based access for those threads. -The following shape lets a user sign in through Supabase and open GitHub pull requests as themselves. After the user has separately authorized GitHub, your application stores the GitHub grant keyed by the Supabase user id. `getGitHubAccessToken` is application code: it looks up and refreshes that grant in your server-side credential store. - -```ts identity.ts -import { defineIdentity, providers } from "managed-deepagents"; -import { getGitHubAccessToken } from "./github-credentials.js"; - -export const identity = defineIdentity({ - ingress: { - http: { - mode: "validated_token", - providers: [providers.supabase({ projectRef: "your-project-ref" })], - }, - }, - tenancy: "single", - scoping: { - threads: "actor", - memory: "actor", - credentials: "custom", - }, - credentials: { - async resolve({ identity, target }) { - if (target.name !== "github") { - throw new Error(`No credentials configured for ${target.name}.`); - } - - const credential = await getGitHubAccessToken(identity.actor.id); - if (!credential) { - throw new Error("Connect GitHub before using GitHub tools."); - } - - return { - headers: { Authorization: `Bearer ${credential.token}` }, - expiresAt: credential.expiresAt.toISOString(), - }; - }, - }, -}); -``` - -In a GitHub tool, request the headers with `await runtime.credentials.for({ kind: "connection", name: "github", intent: "write" })` and pass them to your GitHub client. - -To expose LangSmith capabilities to browsers or other untrusted callers, add a [LangSmith connector](/langsmith/managed-deep-agents-connectors/langsmith).

That keeps the same guest actor across reloads until `exp` and lets you handle rate limits before calling the deployment. - - - Reclaim a token when the current one is expired or missing. While a token is still valid, reuse it so the guest keeps the same actor id, threads, and memory scope for the token lifetime. - - - - JWKS by default (asymmetric JWTs). Maps `sub` → actor.

It copies from a project-defined seed file if one exists, or falls back to a built-in default template. This ensures the agent has its memory instructions available from the first turn, rather than starting with an empty file. - -## Org memory (read-only) +Keep hot memory compact because it consumes context on every run. Put detailed material—such as procedures, decision logs, and research notes—in cold files, and link to them from hot memory when useful. -Optional org-wide facts live under Context Hub `org-memory/` and mount at `/memories/org`. Agents may **read** org memory; the runtime denies writes under `/memories/org/**`. Humans or org tooling update that tree, not the agent. For updating Context Hub files, use the [Context Hub](/langsmith/use-the-context-hub) API or CLI. +The agent reads and updates memory with `read_file`, `edit_file`, and `write_file`. Writes elsewhere, including elsewhere under `/memories/`, are not durable. -## Local development + +Memory is shared by every caller of the deployment, and every caller can influence it.

When you update the Managed Deep Agents SDK in your project, rebuild so `.mda/build/__runtime__` picks up the new runtime. The runtime is copied at compile time, so SDK changes do not take effect until you rebuild. +The agent decides what to remember based on prompting. To make the policy explicit, add guidance like the following to `instructions.md` and adapt it to your application: -## Disable managed memory - -Use `disableMemory` for stateless agents or when you manage persistence externally. Set `disableMemory` / `disable_memory` on the agent definition to skip hot injection and the `/memories/user` memory wiring.

Memory stores knowledge the agent learns and uses across threads. Use instructions to tell the agent what kinds of shared knowledge are worth remembering. - - -## Deploy and Context Hub - -On `mda deploy`, Managed Deep Agents syncs deploy-owned `instructions.md` and `skills/**` into the Context Hub agent repo and seeds agent memory when needed. Existing `memories/**` content is preserved. The sync and seeding behavior mirrors [local development](#local-development).

Confirm the call succeeded and that the target path is under `/memories/user/`. Verify that identity scoping is configured correctly. Writes outside the remounted slice are denied. - - -If hot memory at `/memories/user/AGENTS.md` grows too large, it consumes tokens from every request's system prompt. Move detailed content to cold files under `/memories/user/archive/` and keep only preferences and pointers in hot memory. - - -This is a misconfiguration, not a platform issue. Verify that `scoping.memory` is set to `actor` or `tenant` (not `agent`). Check that the identity declaration is present and that the ingress mode correctly resolves the caller. Inspect `runtime.identity` in traces to confirm the resolved actor and tenant ids. For more information, see [Identity](/langsmith/managed-deep-agents-identity). - - -The runtime creates `/memories/user/AGENTS.md` from the seed template only when the file does not already exist. If a user reports overwritten content, the file was likely absent when the slice was first accessed, so the runtime seeded a fresh copy.
