MCP-Plugin-dotnet vs fastapi_mcp

MCP-Plugin-dotnet: MCP Plugin for .NET is a comprehensive solution for integrating .NET applications with the Model Context Protocol (MCP). It allows exposing methods and data as Tools, Prompts, and Resources to AI assistants. It uses a Bridge Architecture with SignalR for real-time bidirectional communication, solving the independent lifecycle problem for heavy .NET applications like Unity or WPF.; 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).
