Notes and caveats

  • Repository renamed from googleapis/genai-toolbox.
  • Database credentials come from environment variables per the prebuilt configs reference; tool sets vary by --prebuilt database so no single tool list.
  • Can also run as a local HTTP server at http://127.0.0.1:5000/mcp.
  • Google points users wanting a managed option to the Google Cloud remote MCP servers.
