Your auto-generated MCP server is now available at `https://app.base.url/mcp`. ## Documentation, Examples and Advanced Usage FastAPI-MCP provides [comprehensive documentation](https://fastapi-mcp.tadata.com/). Additionaly, check out the [examples directory](examples) for code samples demonstrating these features in action. ## FastAPI-first Approach 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](https://fastapi-mcp.tadata.com/advanced/deploy#deploying-separately-from-original-fastapi-app) is also supported) This design philosophy ensures minimum friction when adding MCP capabilities to your existing FastAPI services. ## Development and Contributing Thank you for considering contributing to FastAPI-MCP!
