AWS Agent Registry runtime discovery walkthrough
What you need to know
AWS published a walkthrough showing an orchestrator agent using AWS Agent Registry to discover MCP servers and A2A agents at runtime rather than having them hardcoded. The sample deploys an order-management MCP server through Amazon Bedrock AgentCore Gateway and two A2A agents on AgentCore runtime; the orchestrator searches approved records, builds request-scoped clients, and tears them down after each turn. Registry search returns descriptors but not invocation credentials, which are fetched separately via Cognito OAuth and boto3 IAM signing.
