MCP-Plugin-dotnet

What it does

MCP-Plugin-dotnet is a .NET implementation of the Model Context Protocol (MCP) that allows developers to expose their application's methods, data, and functionality as MCP-compatible tools, prompts, and resources. This enables AI models like Claude and ChatGPT to directly interact with .NET applications and access their capabilities through a standardized protocol.

How to set up

Installation involves integrating the MCP-Plugin-dotnet NuGet package into your .NET project, configuring the plugin with your application's methods and data sources using reflection, and selecting your preferred transport mechanism (SignalR, stdio, or HTTP). The lightweight server component handles all protocol communication with connected AI clients, requiring minimal configuration to get started.

Key features

• Automatic exposure of .NET methods and properties as MCP tools via reflection
• Support for multiple transport protocols: SignalR, stdio, and HTTP
• Lightweight in-app plugin architecture with minimal overhead
• Native integration with Model Context Protocol specification
• Support for prompts and resources alongside tools
• Compatible with multiple AI platforms including Claude and ChatGPT
