Gemini CLI

Google’s terminal coding tool. Only the registration command and the rules file name (GEMINI.md) differ; everything else is the same.

Install

Install and sign in to Gemini CLI following Google’s instructions. Check:

gemini --version

Register

Terminal

gemini mcp add cadxray uvx --from git+https://github.com/WaveSimm/cadxray#subdirectory=bridge cadxray

Unlike Codex, there is no -- separator. Or write it into ~/.gemini/settings.json directly.

~/.gemini/settings.json

{
  "mcpServers": {
    "cadxray": {
      "command": "uvx",
      "args": ["--from", "git+https://github.com/WaveSimm/cadxray#subdirectory=bridge", "cadxray"]
    }
  }
}

If you already have other MCP servers, add just the "cadxray" entry inside mcpServers. If you changed the port, append "--port", "9878" to args.

Check the connection

With FreeCAD running, open gemini and type /mcp. Seeing cadxray and its tool list is enough.

Say this

Check whether cadxray can reach FreeCAD and tell me the version.

The rules file — GEMINI.md

Gemini reads GEMINI.md from the working folder. Save cadxray’s CLAUDE.md under that name.

Terminal

mkdir C:\cad-work
cd C:\cad-work
curl -o GEMINI.md https://raw.githubusercontent.com/WaveSimm/cadxray/master/CLAUDE.md
gemini

What is different about this tool

• Screenshots: image display depends on the version. If they do not show, look at the FreeCAD window.
• A slow first connection is the 10–30 seconds spent downloading the bridge. If the tools do not appear, call /mcp once more.
• The prompts are the same everywhere. See Writing prompts.
