How to connect CodeMap

CodeMap runs locally from a .NET package published to NuGet: codemap-mcp version 1.4.0. It speaks MCP over stdio, so the client starts it as a program and talks to it through standard input and output. It needs the .NET SDK; run as a .NET tool. It reads the environment variable CODEMAP_CACHE_DIR; set it in the client's configuration for this server.
