What is FastAPI MCP Server?
FastAPI MCP Server is a lightweight, high-performance MCP server implementation designed to simplify interactions between AI models and user applications. It leverages FastAPI's asynchronous features and schema validation capabilities, combined with SSE technology for low-latency real-time communication, and supports concurrent multi-user, multi-model interactions through a session management system.
How to use FastAPI MCP Server?
To use the FastAPI MCP Server, clone the repository, set up a virtual environment, install dependencies (preferably using uv), configure environment variables (including database connection), implement custom API key verification logic, and start the server using Python or uv. Register custom tools in the tools/ directory and configure the server accordingly.
