[DigitalToday reporter Chi-gyu Hwang (황치규)] Amazon Web Services (AWS) said on April 9 it launched AWS Agent Registry, which enables companies to register, search and reuse AI agents, tools and skills.

The New Stack reported that Agent Registry is part of AWS AgentCore and can register agents that run outside the AWS platform, including in other cloud environments and on-premises.

AWS said, "No organization runs its entire agent environment within a single vendor," and added, "A registry that covers only part makes the rest invisible, and invisible agents cannot be discovered, managed or reused."

An OutSystems survey found that virtually all companies are considering using AI agents, but only about one-third have a centralized AI governance approach. AWS pointed out, "Without a central registry, developers end up looking for third-party tools externally or duplicating what another team has already built."

AWS Agent Registry stores metadata for agents, tools, MCP servers and agent skills. It includes the protocols used, the functions provided and how to run them. Agents can be registered through the AWS console, SDK or API, or the registry automatically collects details when MCP or Agent-2-Agent endpoints are connected. Clients such as Claude Code and the AWS Kiro IDE can also query available tools through the registry API and MCP servers.

It also provides governance features. Administrators can separately set permissions to register agents and to search, and can build approval pipelines that integrate with existing approval workflows.

Agent registries are not a new service. Microsoft announced Agent 365 in November 2025, and Google Cloud also runs an agent registry within Vertex AI Agent Builder. In the open source community, Solo.io provides an agent registry project to the CNCF.
