A token-efficient MCP (Model Context Protocol) server for .NET codebase navigation, powered by Roslyn semantic analysis. Designed for use with [Claude Code](https://docs.anthropic.com/en/docs/claude-code).
Instead of reading entire `.cs` files (500-2000+ tokens each), Claude Code queries this MCP server and receives focused, semantic results (30-150 tokens). This dramatically reduces token consumption when working with large .NET solutions.
