About CodeMap

CodeMap is an MCP server published by the GitHub account bbajt. Roslyn-powered MCP server for C#/VB.NET. Query symbols, call graphs, and facts. 90%+ token savings.

It runs on your own machine: your AI client starts it from the NuGet package codemap-mcp at version 1.4.0.

It asks for no keys or passwords.

Version 1.4.0 was published on 2 April 2026, and the source code is public, so you can read it before installing.

Written from the registry entry. 7 automated checks on registry metadata: 4 pass, 0 warn, 0 fail, 3 info. How we check.
