AWS Agent Registry Enables Runtime Tool Discovery
Current overview (not historical)
After the release of the AWS Agent Registry, orchestrators can now discover and use MCP servers and A2A agents at runtime through semantic search, eliminating the need to redeploy code. Publishers must register protocol‑specific and searchable descriptions, and only records that pass review are returned to queries. When a natural‑language query is issued, the internal agents and their clients are automatically torn down after the search completes. This feature addresses the challenge of managing hard‑coded tools as the number of agents scales up.

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.
