Civil 3D MCP

AI writes and runs C# inside Civil 3D: surfaces, alignments, COGO points

Runs as a server Claude Code connects to. It needs its own configuration, and some servers need an API key.

Install just this one

Run in your terminal — needs Node

npx archtmpl@latest --mcp civil3d-mcp

First time? The whole install, step by step

Open Claude Code — the terminal version or the desktop app, either one.
In a terminal, paste the line above and press Enter. In the app, paste it into the chat and ask Claude to run it.
Restart Claude Code. That's the whole install.
