Fleet includes a built-in MCP server that exposes 32 tools over JSON-RPC on stdio. Run fleet mcp serve and point any MCP-compatible client at it — Claude Code discovers it automatically via .mcp.json in the repo root. The tools cover the full Fleet runtime surface: listing, creating, starting, and stopping agents; reading agent logs and output; publishing and reading fabric events; running and approving pipelines; assigning and updating tasks; reading the fleet log and dashboard; and surfacing brain insights.
This lets a Claude Code conversation query which agents are running, dispatch a task to a specific agent, check whether a PR was approved, or read recent fabric events without leaving the conversation. For anyone building on top of Fleet, the MCP server is also the cleanest programmatic interface to Fleet's state — it reads Fleet's SQLite database and configuration directly and does not require the watcher daemon to be running.
