Proof1 independent outlet
Key points
- AWS Agent Registry is a managed service for cataloging and discovering Model Context Protocol (MCP) servers, agents, and agent skills.
- The code deploys an order-management MCP server through Amazon Bedrock AgentCore Gateway, a capability of Amazon Bedrock AgentCore, two agent-to-agent (A2A) agents on AgentCore runtime, a Registry, and an orchestrator.
- Figure 1: Without AWS Agent Registry (left), endpoints are hardcoded and adding a new agent means code changes plus redeployment.
- With AWS Agent Registry (right), the orchestrator discovers capabilities through semantic search and new integrations are usable after registration and approval
