csharp-sdk vs ken
csharp-sdk: 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.; ken: Ken is a pure Go port of semble, providing fast hybrid code search for agents with drop-in MCP compatibility. It offers a single static binary distribution, approximately 44x fewer tokens than grep+Read at recall@10, and supports indexing source code and documentation. The retrieval algorithm is a verbatim port of semble's hybrid BM25 + Model2Vec approach.
