MCP-Plugin-dotnet vs fastmcp
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.; fastmcp: FastMCP is a standard framework for building Model Context Protocol (MCP) applications, which connect LLMs to tools and data. It simplifies the process by automatically generating schemas, validation, and documentation for tools, and managing transport negotiation and authentication for server connections. FastMCP offers a comprehensive solution for developing, deploying, and scaling MCP-powered systems.
