MCPSharp and MCP-Plugin-dotnet
These are complements: MCPSharp provides the foundational .NET library and protocol implementation for building MCP servers, while MCP-Plugin-dotnet builds on top of that abstraction to offer a higher-level plugin architecture for exposing application methods and data as MCP resources.
About MCPSharp
afrise/MCPSharp
MCPSharp is a .NET library that helps you build Model Context Protocol (MCP) servers and clients - the standardized API protocol used by AI assistants and models.
This is a .NET library for developers building AI applications. It helps you create special functions and tools that AI models and assistants can use, and connect to existing AI services using a standardized protocol called Model Context Protocol (MCP). Developers write their C# methods, and the library handles the complex communication, allowing AI systems to discover and call those methods.
About MCP-Plugin-dotnet
IvanMurzak/MCP-Plugin-dotnet
.NET MCP bridge: expose app methods/data as MCP tools, prompts, and resources via an in-app plugin + lightweight server (SignalR; stdio/http).
This tool helps .NET developers integrate their desktop applications, game servers, or Unity projects with AI assistants like Claude. It allows the AI to trigger methods, access data, and utilize prompts from a running .NET application. The developer defines what their app can offer, and the AI can then interact with the live application instance.
