Examples

Add this entry to .gemini/settings.json in your project. Merge it with existing settings rather than replacing them.

{
  "mcpServers": {
    "r3": {
      "command": "npx",
      "args": ["-y", "@n3wth/r3"]
    }
  }
}

Start Antigravity CLI and run /mcp to inspect the server connection and available tools. Review tool calls before granting access to private data.

See the Antigravity CLI MCP documentation for configuration and troubleshooting.

Ask Gemini to store a non-sensitive project preference with r3. Start a fresh session and ask it to search for that preference. Check the tool result rather than assuming the model recalled it.
