AG2, formerly AutoGen, is an open-source Python framework for building LLM-driven agents and multi-agent systems, described by its authors as an 'AgentOS'. The repository indicates support for protocols like A2A and MCP and ships an AGENTS.md for coding tools.

Use it when you want an established, Apache-2.0 Python framework for orchestrating multiple LLM agents.

Use it to

  • Build multi-agent LLM applications in Python
  • Integrate agents via A2A and MCP protocols
  • Prototype agentic workflows with LLMs
  • Extend an open-source agent framework
