AWS Agent Registry reaches general availability

AWS announced general availability of Agent Registry, a governed catalog that lets organizations register, discover and manage every agent, tool, skill and custom resource across their environment. VP Swami Sivasubramanian said the product answers a recurring customer complaint: 'teams don't have visibility into what's already been built, who owns it, or what's been approved.' A highlighted capability is organization-wide auto-detection — Registry automatically discovers agents and MCP servers running on AgentCore runtime and gateway across every account. Registry resources, including MCP servers, are also discoverable directly within Amazon Quick.

The mechanism matters because agent sprawl is the emerging enterprise problem: as AWS's Matt Wood put it, agents are 'being created in new places, by new authors, using new tools,' living inside applications, IDEs and business processes rather than formal deployment pipelines. A registry with publishing, curation, discovery and governance workflows is essentially source-control-plus-catalog for the agent era.

Competitively it extends AWS's AgentCore platform play — which this cycle also moved payments to GA, letting agents autonomously pay for APIs via x402 and Coinbase — and stakes a claim on the governance layer before rivals do. Microsoft's Foundry and Google's Managed Agents are chasing the same enterprise-agent control plane.

The watch item is adoption friction: registries only work if teams actually publish to them, and auto-detection helps but can't catch shadow agents built outside AgentCore. Enterprises evaluating agent governance will test whether Registry's discovery is comprehensive enough to be the system of record.
