Active·★ 4.4k·NOASSERTION·Updated 2026-07-16
★ Essential★ Dev Tooling

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.

csharp-sdk is currently grouped under Dev Tooling, which makes it easier to evaluate through workflow fit instead of isolated features alone. Based on the available data, it leans most heavily toward Implement and interact with MCP clients and servers and Integrating .NET applications with the Model Context Protocol. The listed license is NOASSERTION, which is useful when adoption constraints matter. It also shows measurable community traction with 4.4k GitHub stars.

Trade-offs

!This page does not list a concrete install command, so you may need to verify setup steps in the official docs before adopting it.
!Compatibility coverage looks narrow, so it is worth validating your target runtime before committing to it.
!There are at least 8 related tools in the same category, so the best choice is easier to make after side-by-side comparison.

How it compares

≈csharp-sdk sits in the Dev Tooling category, so it makes more sense to evaluate it alongside tools like fastmcp instead of in isolation.
≈If your main need is closer to "Integrating .NET applications with the Model Context Protocol", that use case is a better lens for comparison than broad feature checklists alone.
≈csharp-sdk uses a NOASSERTION license, and community traction are both easier to judge in category context.
