mcpo vs fastapi_mcp
mcpo: mcpo is a simple proxy that transforms any Model Context Protocol (MCP) server command into a standard RESTful OpenAPI server. This allows LLM agents and other applications to seamlessly interact with MCP tools without custom protocols or glue code.; 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.
