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.

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.
