Gasoline + Antigravity

Gasoline is an open-source MCP server that gives Antigravity’s AI agent access to browser console logs, network errors, exceptions, WebSocket events, and live DOM state. Zero dependencies.

Auto-Install

gasoline-mcp --install antigravity

Manual Configuration

Add to ~/.gemini/antigravity/mcp_config.json:

{
  "mcpServers": {
    "gasoline": {
      "command": "gasoline-mcp",
      "args": []
    }
  }
}

If using npx:

{
  "mcpServers": {
    "gasoline": {
      "command": "npx",
      "args": ["-y", "gasoline-mcp"]
    }
  }
}

Antigravity does not support ${workspaceFolder} — use absolute paths only.

Usage

After configuring, open an Agent session in Antigravity. The AI agent can access Gasoline’s full MCP toolset.

Troubleshooting

1. Restart Antigravity after editing config
2. Use absolute paths — ${workspaceFolder} is not supported
3. Verify extension popup shows “Connected”
