{
  "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.

Try a memory round trip

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.
