- [Delete an agent](https://docs.langchain.com/langsmith/managed-deep-agents-api/agents/delete-agent.md): Delete the agent. The call is idempotent: deleting a non-existent agent returns `204`. Deletion does not cascade to the agent's threads — existing threads remain queryable but cannot start new runs (attempts return `502`). Delete threads explicitly when you want to clean them up.
- [Get an agent](https://docs.langchain.com/langsmith/managed-deep-agents-api/agents/get-agent.md): Return the specified agent, including metadata, permissions, runtime, extras, and the parsed file tree at the latest commit. Pass `include_files=true` to include the raw file map.

- [Register an MCP server](https://docs.langchain.com/langsmith/managed-deep-agents-api/mcp-servers/create-mcp-server.md): Register an MCP server in the caller's workspace and attach credential headers. Once registered, any agent tool whose `mcp_server_url` matches `url` will have the stored headers attached automatically at invocation time.
- [Delete an MCP server](https://docs.langchain.com/langsmith/managed-deep-agents-api/mcp-servers/delete-mcp-server.md): Delete an MCP server. The call is idempotent: deleting a non-existent server returns `204`. After deletion, agents whose tools reference this server's URL will no longer have the stored headers attached at invocation time.
- [Get an MCP server](https://docs.langchain.com/langsmith/managed-deep-agents-api/mcp-servers/get-mcp-server.md): Fetch a single MCP server by ID.

Passing `headers` replaces the entire stored header array — partial diffs are not supported. Use this endpoint to rotate credentials.
- [Create a thread run](https://docs.langchain.com/langsmith/managed-deep-agents-api/runs/create-thread-run.md): Start a run on the thread. This endpoint is proxied to the upstream agent runtime and accepts its run payload. Include the assistant or agent identifier and run inputs in the request body.
- [Resolve an interrupt](https://docs.langchain.com/langsmith/managed-deep-agents-api/runs/resolve-interrupt.md): Complete a human-interrupt pause on the thread without sending new input, allowing execution to continue or finish. On success the response has no body.
- [Stream a thread run](https://docs.langchain.com/langsmith/managed-deep-agents-api/runs/stream-thread-run.md): Start a run on a thread and stream output as server-sent events. The request must use `agent_id`; `assistant_id` is reserved for server-side forwarding and is rejected.
- [Count threads](https://docs.langchain.com/langsmith/managed-deep-agents-api/threads/count-threads.md): Count threads matching the specified criteria. Request and response bodies are proxied unchanged to the upstream agent runtime.
- [Create a thread](https://docs.langchain.com/langsmith/managed-deep-agents-api/threads/create-thread.md): Create a thread bound to a Managed Deep Agent. Use the returned thread ID to start runs.
- [Get thread](https://docs.langchain.com/langsmith/managed-deep-agents-api/threads/get-thread.md): Return thread metadata and status for the given thread ID.
