#roslyn

An MCP server that gives AI agents deep understanding of C# codebases via Roslyn — type search, dependency graphs, usage analysis, and architecture overviews, all from a live in-memory compilation.

MCP Server for Visual Studio bridges your IDE with AI coding assistants like Claude Code, Cursor, Windsurf, and Cline. Unlike file-based tools, this extension provides what AI agents CAN'T do alone: • IntelliSense & semantic code understanding (powered by Roslyn) • Symbol search - definitions, usages, inheritance hierarchies • Solution/project navigation and document outlines • Build execution with clean, structured error output • Async test execution with progress tracking • Solution-wide refactoring (rename symbols across all files) 20 tools designed for AI consumption with token-efficient output. Windows only. Supports VS 2022 (17.13+) and VS 2026.
