why it's a big deal

  • Turns existing FastAPI endpoints into MCP tools that AI agents can call, so teams expose an API to agents without writing a separate MCP server.
  • Reuses FastAPI's Depends() dependency injection for auth, so existing endpoint security carries over to the MCP interface.
  • Preserves request and response schemas plus Swagger/OpenAPI documentation, so tool definitions stay in sync with the API they wrap.

under the hood

  • Written in Python, requires 3.10 or newer, MIT licensed, at version 0.4.0 with about 12k stars.
  • Mounts an MCP server at /mcp with two lines, FastApiMCP(app) then mcp.mount(), either on the same app or as a separate server.
  • Communicates with the FastAPI app over the ASGI interface directly rather than making HTTP calls, and models tools from FastAPI internals instead of generic OpenAPI conversion.
