MCP FastAPI Application Template

🌏 中文 | English

This project provides an MCP application template integrated with FastAPI.

  • Support for multiple MCP mounting
  • Support for command-line invocation in Stdio mode
  • Support for SSE / StreamableHTTP / WebSocket
  • Support for packaging and distribution

Starting from v0.1.2, we use BetterFastMCP to replace FastMCP, providing more comprehensive features than the official FastMCP:

  • Support for Pydantic models as input parameters, enabling more complex input parameter types and convenient description addition
  • Support for WebSocket as transport layer, access by /{mcp_name}/websocket/ws
