metamcp vs fastapi_mcp
metamcp: MetaMCP is an MCP proxy designed to dynamically aggregate multiple MCP servers into a single unified server, applying custom middlewares. It serves as an infrastructure to host these composed MCP servers via a unified endpoint, compatible with any MCP client through SSE, Streamable HTTP, or OpenAPI.; 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 metamcp if…Aggregating and hosting multiple MCP servers under unified, authenticated endpoints with namespaces.
Choose fastapi_mcp if…Integrating FastAPI services as tools for large language models (LLMs) that support MCP.
