Introducing agent-to-agent protocol support in Amazon Bedrock AgentCore Runtime
Machine Learning Blog
Amazon Bedrock AgentCore Runtime now supports Agent-to-Agent (A2A) protocol, enabling AI agents built with different frameworks to discover peers, share capabilities, and coordinate actions using standardized communication.
- A2A protocol allows agents from different frameworks (Strands, OpenAI SDK, LangGraph, Google ADK, Claude SDK) to communicate seamlessly
- Agents can discover capabilities via standardized agent cards and coordinate complex workflows across platforms
- Multi-agent system example: monitoring agent (Strands) detects issues, operational agent (OpenAI) searches for solutions, host agent (Google ADK) orchestrates
- Security features include OAuth 2.0 and AWS IAM authentication, VPC connectivity, and AWS PrivateLink support
- Deployment includes automated scripts, CloudFormation templates, and React frontend for incident response workflows
- Supports stateless HTTP servers, authenticated agent cards, lifecycle management, and cross-account AWS access
A2A protocol on AgentCore Runtime eliminates integration complexity for multi-agent systems, enabling organizations to build sophisticated agentic solutions with standardized interoperability across frameworks, models, and hosting infrastructure.
