Introducing agent-to-agent protocol support in Amazon Bedrock AgentCore Runtime

We recently announced the support for Agent-to-Agent (A2A) protocol on Amazon Bedrock AgentCore Runtime. With this addition, agents can discover peers, share capabilities, and coordinate actions across platforms using standardized communication.

Amazon Bedrock AgentCore Runtime provides a secure, serverless environment designed for deploying AI agents and tools. It works with any framework and model, supports real-time and long-running workloads, and supports session isolation with built-in authentication. With support for MCP, and now the A2A protocol, Bedrock AgentCore Runtime enables seamless communication between agents. Agents built using different frameworks, Strands Agents, OpenAI Agents SDK, LangGraph, Google ADK, or Claude Agents SDK, can share context, capabilities, and reasoning in a common, verifiable format.

In this post, we demonstrate how you can use the A2A protocol for AI agents built with different frameworks to collaborate seamlessly. You’ll learn how to deploy A2A servers on AgentCore Runtime, configure agent discovery and authentication, and ...
