The official C# SDK for Model Context Protocol servers and clients. Maintained in collaboration with Microsoft.

The MCP C# SDK is the official C# SDK for the Model Context Protocol, designed to enable .NET applications, services, and libraries to implement and interact with MCP clients and servers. The Model Context Protocol (MCP) itself is an open protocol that standardizes how applications provide context to Large Language Models (LLMs), facilitating secure integration between LLMs and various data sources and tools.
