MCP C# SDK

NuGet version

The official C# SDK for the Model Context Protocol, enabling .NET applications, services, and libraries to implement and interact with MCP clients and servers. Please visit the API documentation for more details on available functionality.

Packages

This SDK consists of three main packages:

  • ModelContextProtocol.Core NuGet version - For projects that only need to use the client or low-level server APIs and want the minimum number of dependencies.

  • ModelContextProtocol NuGet version - The main package with hosting and dependency injection extensions. References ModelContextProtocol.Core. This is the right fit for most projects that don't need HTTP server capabilities.

  • ModelContextProtocol.AspNetCore NuGet version - The library for HTTP-based MCP servers. References ModelContextProtocol.

Getting Started

To get started, see the Getting Started guide for installation instructions, package-selection guidance, and complete examples for both clients and servers.

You can also browse the samples directory and the API documentation for more details on available functionality.

About MCP

The Model Context Protocol (MCP) is an open protocol that standardizes how applications provide context to Large Language Models (LLMs). It enables secure integration between LLMs and various data sources and tools.

Senparc.Weixin.AspNet

微信 SDK - Senparc.Weixin.AspNet 模块 Senparc.Weixin SDK 开源项目： https://github.com/JeffreySu/WeiXinMPSDK
Volo.Abp.Cli.Core

Package Description
Microsoft.Debugging.Platform.DbgX

Wraps DbgEng in a managed Task Asynchronous Pattern (e.g. async/await) so that consumers of this library do not need to be aware of the oddities of the dbgeng threading model. It creates a child process to host the engine out of process (using EngHost.exe) to allow native 32/64 bit debugging of binaries.
