概要

What is 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. It allows you to create MCP-compliant tools and functions, connect to MCP servers from C# code, and expose .NET methods as MCP endpoints using simple attributes.

How to use MCPSharp?

Install the NuGet package with dotnet add package MCPSharp. Define a class and mark methods with the [McpTool] attribute, then start the server by calling MCPServer.StartAsync("serverName", "1.0.0"). Optionally, register tools from referenced libraries using MCPServer.Register<T>().

Key features of MCPSharp

  • Easy-to-use attribute-based API ([McpTool], [McpResource])
  • Built-in JSON-RPC support with automatic request/response handling
  • Automatic parameter validation and type conversion
  • Rich documentation support through XML comments
  • Dynamic tool registration with custom implementation logic
  • Integration with Microsoft.Extensions.AI and Semantic Kernel

Use cases of MCPSharp

  • Create tools that AI assistants like Anthropic's Claude Desktop can use
  • Build MCP-compliant APIs without dealing with protocol details
  • Expose existing .NET code as MCP endpoints
  • Add AI capabilities to applications through standardized interfaces
  • Integrate with Microsoft.Extensions.AI or Semantic Kernel without vendor lock-in

よくある質問

1

What are the runtime dependencies for MCPSharp?

MCPSharp requires any version of .NET that supports .NET Standard 2.0.

2

How do I define a tool in MCPSharp?

Create a class and mark a method with the `[McpTool]` attribute, optionally providing a name and description. Use `[McpParameter]` to specify parameter metadata.

3

Can I use MCPSharp with Semantic Kernel?

Yes. Mark methods with `[KernelFunction]` and `[Description]`, then register the class with `MCPServer.Register<T>()`. The server will expose those methods as MCP tools.

4

How does MCPSharp integrate with Microsoft.Extensions.AI?

On the client side, call `client.GetFunctionsAsync()` to obtain a list of `AIFunction` objects that can be plugged into `ChatOptions.Tools` for any `IChatClient` implementation.

5

Are there any migration notes from previous versions?

Yes. The `[McpFunction]` attribute is deprecated and replaced with `[McpTool]`. Also, use `MCPServer.Register<T>()` instead of the deprecated `MCPServer.RegisterTool<T>()`.
