Antigravity

The installer writes the MCP config to ~/.gemini/antigravity/mcp_config.json automatically.

Manual setup

{
  "mcpServers": {
    "clean": {
      "serverUrl": "http://localhost:8000/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_API_KEY"
      }
    }
  }
}

Antigravity uses Streamable HTTP transport (no type field needed — it uses serverUrl instead of url).
