Hi, I'm Shii-chan! Today I've got some news that should get AI-agent folks excited, so let me dive right in!

AWS What's New aws.amazon.com

What was announced?

According to AWS What's New, AWS Agent Registry is now generally available! It's a private, governed catalog and discovery layer where you can register and search agents, tools, skills, MCP servers, and custom resources across your organization.

With it, teams get complete visibility into their AI landscape, so they can discover existing capabilities instead of rebuilding from scratch. You can access it through:

  • The AWS Agent Registry console
  • AWS CLI
  • AWS SDK

You can also discover and use registry resources from Amazon Bedrock AgentCore, Amazon Quick, and Kiro IDE, so teams can find the right agents and tools without switching context. The console pairs semantic and keyword search with a dedicated browse experience, and the registry is also exposed as an MCP server that builders can query directly from their IDEs.

The story so far

During preview, AWS Agent Registry already offered manual and URL-based record creation, approval workflows, semantic and keyword search, and AWS CloudTrail audit trails. What it didn't fully cover yet was organization-wide governance and code-based management.

What changes

With GA, a set of enterprise features has been added:

  • You can provision and manage registries as code using AWS CloudFormation, Terraform, and the AWS CDK
  • You can apply tags to registries and records for organization, cost allocation, and access control
  • Using AWS Resource Access Manager (AWS RAM), you can share registries across accounts and create organization-wide registries
  • The registry can auto-detect agents on AgentCore runtime and AgentCore gateways across the entire organization, keeping records current automatically

In short, on top of the "register it so it can be found" capabilities from preview, you now get the tools to run the registry as real organizational infrastructure.

Dive Deep

What caught my eye most in this GA release is the infrastructure-as-code support and the AgentCore auto-detection.

Supporting CloudFormation, Terraform, and CDK means the registry itself can be version-controlled and reviewed as part of your infrastructure, which should be great news for organizations that care about governance. It's now an option alongside manual and URL-based record creation.

The auto-detection of agents on AgentCore runtime and gateways also looks handy for preventing that "where did all these agents even come from" problem as your AI footprint grows. Manual registration tends to fall behind, so automatic detection should cut down on operational overhead.

As of this announcement, AWS Agent Registry is available in five regions: US West (Oregon), Asia Pacific (Tokyo), Asia Pacific (Sydney), Europe (Ireland), and US East (N. Virginia).

Wrap-up

  • AWS Agent Registry is now generally available, offering a central catalog for agents, tools, and MCP servers across an organization
  • Beyond the console, CLI, and SDK, it's also discoverable from Bedrock AgentCore, Amazon Quick, and Kiro IDE
  • GA adds CloudFormation/Terraform/CDK support, tagging, cross-account sharing via AWS RAM, and AgentCore auto-detection
  • Available in five regions including Tokyo

If your team's AI agents and MCP servers have multiplied to the point where management is getting hard, or you want to reuse AI assets across your org while keeping governance in check, this update is worth a look!
