AutoGen's architecture is built around an event-driven model, where agents communicate asynchronously and can be distributed across services using gRPC. Developers can extend the framework through built-in extensions or community-contributed packages. Key integration points include:
- Docker — for containerized agent execution environments
- Model Context Protocol (MCP) — AutoGen supports MCP servers, enabling standardized tool and context interfaces for agents
- OpenAI — the supported model provider for powering agent intelligence
The framework is fully self-hostable, with no dependency on managed cloud services. AutoGen Studio provides a no-code, web-based UI layer for rapid prototyping alongside the programmatic API.
