Brings Roslyn-powered C# semantic analysis to LLMs via the Model Context Protocol. You get code navigation, symbol resolution, and project structure queries without spinning up a full IDE. Runs over stdio or HTTP, so you can drop it into Claude Desktop, Codex, or any MCP-compatible agent. Part of the Glider family that also includes runtime tracing and TypeScript support. Useful when you need an LLM to understand C# codebases beyond simple text matching: think refactoring assistance, dependency analysis, or answering questions about type hierarchies. Ships as a NuGet package and integrates through marketplace configs for major agent platforms.
