mcp-proxy vs fastapi_mcp
mcp-proxy: mcp-proxy is a versatile tool designed to switch between various server transport protocols, primarily facilitating communication between stdio and SSE/Streamable HTTP. It operates in two main modes: proxying stdio to a remote SSE server, or exposing a local stdio server via an SSE endpoint.; fastapi_mcp: FastAPI-MCP allows you to expose your existing FastAPI endpoints as Model Context Protocol (MCP) tools. It offers native integration with FastAPI, including built-in authentication using existing dependencies, and preserves schemas and documentation.
01
TL;DR
Choose mcp-proxy if…Enable stdio-only clients (e.g., Claude Desktop) to connect to remote SSE/Streamable HTTP servers.
Choose fastapi_mcp if…Integrating FastAPI services as tools for large language models (LLMs) that support MCP.
