reporelay vs fastapi_mcp
reporelay: RepoRelay is a self-hosted code context engine for MCP that allows you to add repositories from any source, index the refs you need, and use them instantly as MCP tools in various clients. It uses tree-sitter parsing, hybrid search (BM25 + pgvector), and runs entirely on your infrastructure.; 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.

When to choose:
- You already have a FastAPI application and want to expose its endpoints as MCP tools while reusing your existing FastAPI authentication dependencies and Swagger schemas.
- You want to mount the MCP server directly onto your ASGI app or deploy it separately under an MIT license.
When to skip:
- You are building a standalone MCP server from scratch rather than wrapping a FastAPI app; use FastMCP or the official MCP Python SDK.
- You need an actively updated repository (last push was November 2025).
