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. With MCPSharp, you can:

• Create MCP-compliant tools and functions that AI models can discover and use
• Connect directly to existing MCP servers from C# code with an easy to use client
• Expose your .NET methods as MCP endpoints with simple attributes
• Handle MCP protocol details and JSON-RPC communication seamlessly

🚀 What's New in MCPSharp

• Microsoft.Extensions.AI Integration: MCPSharp now integrates with Microsoft.Extensions.AI, allowing tools to be exposed as AIFunctions
• Semantic Kernel Support: Add tools using Semantic Kernel's KernelFunctionAttribute
• Dynamic Tool Registration: Register tools on-the-fly with custom implementation logic
• Tool Change Notifications: Server now notifies clients when tools are added, updated, or removed
• Complex Object Parameter Support: Better handling of complex objects in tool parameters
• Better Error Handling: Improved error handling with detailed stack traces
