AG2 + A2A Protocol
AG2 integrates with the Agent-to-Agent (A2A) Protocol, Google's open standard for seamless communication and coordination between AI agents.
What is A2A?
The Agent-to-Agent (A2A) Protocol is an open standard developed by Google that enables AI agents to communicate, discover each other, and collaborate on tasks—regardless of the underlying framework or vendor.
A2A addresses a critical challenge in the AI ecosystem: as organizations deploy multiple specialized agents, these agents need a common language to work together effectively. Without interoperability standards, each integration becomes a custom development effort.
AG2 was among the first frameworks to implement A2A support, enabling your agents to seamlessly communicate with agents built on other platforms like LangChain, CrewAI, and Google's own Vertex AI.
Features
A2A Protocol Capabilities
Agent Discovery
Agents can discover each other's capabilities through standardized Agent Cards that describe available skills and endpoints.
Task Management
Structured task delegation with support for immediate responses, deferred execution, and streaming updates.
Multi-Turn Conversations
Support for extended interactions where agents collaborate over multiple exchanges to complete complex tasks.
Push Notifications
Real-time updates via Server-Sent Events (SSE) for long-running tasks without polling.
Enterprise Security
Built-in authentication and authorization with support for OAuth 2.0 and enterprise identity providers.
