CodeMap

Overview

CodeMap is a Model Context Protocol (MCP) server: Roslyn-powered MCP server for C#/VB.NET. Query symbols, call graphs, and facts. 90%+ token savings. Because it speaks the Model Context Protocol, AI assistants can use CodeMap as a set of callable tools instead of you copy-pasting between apps.

It runs locally: the NuGet package codemap-mcp speaks MCP over stdio on your machine. No credentials are required — it works out of the box. The current release is v1.4.0, with source at bbajt/csharp-code-map on GitHub, where it has earned 17 stars.

On mcp.site, CodeMap sits in the Development category. Any MCP client can use it — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed among them — via the install snippets below.
