AWS Agent Registry for centralized agent discovery and governance is now available in Preview

AWS Agent Registry, available through Amazon Bedrock AgentCore, is now in preview — a private, governed catalog and discovery layer for agents, tools, skills, MCP servers, and custom resources within the organization. It gives teams complete visibility into their AI landscape, enabling them to discover existing agents and tools instead of rebuilding capabilities that already exist. The registry can be accessed via the AgentCore Console UI, APIs (AWS CLI, AWS SDK), or as an MCP server that builders can query and invoke directly from their IDEs. Registry supports both IAM and OAuth (Custom JWT) based access.

Teams can register resources manually through the console or API, or use URL-based discovery, which automatically retrieves metadata such as tool schemas and capability descriptions from a live MCP server or agent endpoint. Records go through an approval workflow where administrators can approve records before they become discoverable, and they can plug the registry into their existing approval workflows to enforce governance policies. AWS CloudTrail provides complete audit trails of all registry access and administrative actions, ensuring compliance and security oversight. For discovery, the registry offers both semantic and keyword search, so developers can quickly find agents by describing their use case in natural language.

AWS Agent Registry (preview) is available in five AWS Regions where AgentCore is available: US West (Oregon), Asia Pacific (Tokyo), Asia Pacific (Sydney), Europe (Ireland), and US East (N. Virginia). Learn more about the registry through the blog, and deep dive using the documentation.
