AWS adds Agent-to-Agent protocol support in Bedrock AgentCore Runtime

Amazon said in an engineering blog that Amazon Bedrock AgentCore Runtime now supports the Agent-to-Agent (A2A) protocol, enabling agents built on different frameworks to discover peers and coordinate via a standard interface.

In the post, AWS lists interoperability with Strands Agents, OpenAI Agents SDK, LangGraph, Google ADK and Claude Agents SDK, and outlines deployment steps for A2A servers on AgentCore Runtime.

AWS demonstrates an enterprise monitoring and incident response system: a host agent (Google ADK) coordinating a monitoring agent (Strands) and an operations agent (OpenAI SDK) over A2A on AgentCore Runtime.

AWS provides complete implementation code for the multi-agent example in its awslabs repository.
