AutoGen is an open-source framework for building single and multi-agent AI applications, designed for developers and researchers. It features an event-driven architecture that enables scalable, distributed agent execution via gRPC, making it suitable for production-grade deployments. Agents are composable and extensible through built-in and community extensions. AutoGen integrates with Docker for containerized environments and supports the Model Context Protocol (MCP), including MCP server support. The framework is self-hostable, giving teams full control over their infrastructure. Model interactions are powered by OpenAI.
