Google Antigravity SDK

Google Antigravity SDK is a Python library that lets developers build AI agents powered by Gemini and Antigravity without managing the agent loop.

What it is good for

  • Building an AI agent that calls custom Python functions as tools
  • Connecting an agent to external MCP servers for extra tools
  • Streaming agent responses into a console or user interface
  • Running an AI agent offline on a local model
