csharp-sdk vs ncp

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.; ncp: NCP (Natural Context Provider) is an MCP aggregator that consolidates 50+ disparate MCP servers into a single unified interface for AI agents. Instead of loading every tool definition upfront and burning tokens, agents use three simple tools — find, code, and run — to discover and invoke any capability on demand. Code mode lets the agent write TypeScript workflows combining multiple tools in one step. NCP reports 97% fewer tokens consumed and 5x faster tool selection compared to loading individual MCP servers.
