Repository-wide counts · Cached 2026-10-04
The Fastapi MCP MCP server is a publicly available community project. Review the upstream repository for installation instructions, supported tools, compatibility, permissions, and current maintenance status.
Configuration, transport, authentication, and runtime requirements vary by project. Open the repository before connecting and use the smallest set of credentials and permissions required.
Open the Fastapi MCP repository to read the latest documentation.
Compare source, connection, and authentication details before choosing an implementation.

Expose your FastAPI endpoints as Model Context Protocol (MCP) tools, with Auth!
Authentication built in, using your existing FastAPI dependencies!
FastAPI-native: Not just another OpenAPI -> MCP converter
Zero/Minimal configuration required - just point it at your FastAPI app and it works
Preserving schemas of your request models and response models
Preserve documentation of all your endpoints, just as it is in Swagger
Flexible deployment - Mount your MCP server to the same app, or deploy separately
ASGI transport - Uses FastAPI's ASGI interface directly for efficient communication
If you prefer a managed hosted solution check out tadata.com.
We recommend using uv, a fast Python package installer:
uv add fastapi-mcp
Alternatively, you can install with pip:
pip install fastapi-mcp
The simplest way to use FastAPI-MCP is to add an MCP server directly to your FastAPI application:
from fastapi import FastAPI
from fastapi_mcp import FastApiMCP
app = FastAPI()
mcp = FastApiMCP(app)
# Mount the MCP server directly to your FastAPI app
mcp.mount()
That's it! Your auto-generated MCP server is now available at https://app.base.url/mcp.
FastAPI-MCP provides comprehensive documentation. Additionaly, check out the examples directory for code samples demonstrating these features in action.
FastAPI-MCP is designed as a native extension of FastAPI, not just a converter that generates MCP tools from your API. This approach offers several key advantages:
Native dependencies: Secure your MCP endpoints using familiar FastAPI Depends() for authentication and authorization
ASGI transport: Communicates directly with your FastAPI app using its ASGI interface, eliminating the need for HTTP calls from the MCP to your API
Unified infrastructure: Your FastAPI app doesn't need to run separately from the MCP server (though separate deployment is also supported)
This design philosophy ensures minimum friction when adding MCP capabilities to your existing FastAPI services.
