AWS Launches Agent Registry to Enable Runtime Tool Discovery for Agents
Original source: AWS Machine Learning BlogRead original
AI brief
AWS has released the Agent Registry, a managed service that lets orchestrators discover Model Context Protocol (MCP) servers and agent‑to‑agent (A2A) agents at runtime via semantic search. By registering tool descriptors and searchable descriptions, teams can add new capabilities without code changes or redeployments, as the orchestrator builds clients from the returned descriptors. The service demonstrates use cases such as order status queries, pricing chains, and refund eligibility checks, all without hardcoding endpoints.
Why it matters
The registry removes the build‑time bottleneck for expanding enterprise APIs, allowing AI agents to scale with new tools on their own release cadence.
