Gasoline + Gemini CLI

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

Auto-Install

gasoline-mcp --install gemini

Manual Configuration

Add to ~/.gemini/settings.json:

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

If using npx:

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

Usage

After configuring, Gemini CLI can access Gasoline’s full MCP toolset.

Troubleshooting

1. Restart Gemini CLI after editing settings
2. Verify extension popup shows “Connected”
3. Test: Ask Gemini “What browser errors do you see?”
