Google Gemini

The Gemini app at gemini.google.com can’t reach programs on your computer — its connections are made from Google’s cloud. Google’s tool for working with local software is Antigravity, its agentic IDE and CLI (the successor to Gemini CLI), powered by the same Gemini models.

You need: Antigravity (free download, sign in with your Google account).

Setup

Open (or create) the file ~/.gemini/config/mcp_config.json and add:

{
  "mcpServers": {
    "artisan": {
      "serverUrl": "http://127.0.0.1:9280/mcp"
    }
  }
}

Note: if your company uses Gemini Code Assist (Standard/Enterprise) you may still have the classic Gemini CLI — there, run gemini mcp add --transport http artisan http://127.0.0.1:9280/mcp instead.

Check it’s connected

In the Antigravity CLI, type /mcp — the MCP Manager shows artisan as active. In the Antigravity IDE, check the ⋯ menu → MCP Servers in the agent panel.

Try it

With Rhino open, ask Gemini:

“Create a round 1 ct diamond.”

The stone appears in your Rhino viewport. Not working? See Troubleshooting.
