AWS launches Agent Registry

Amazon Web Services has put its new Agent Registry into preview, giving companies one catalog to track and govern artificial intelligence agents across teams. (aws.amazon.com) The service is available through Amazon Bedrock AgentCore and runs in five compute regions, according to Amazon Web Services’ April 9 announcement. Amazon Web Services said the registry can list agents, tools, skills, Model Context Protocol servers, and custom resources in one searchable system. (aws.amazon.com) Each registry record can store ownership, capabilities, protocols, and invocation methods, which are the instructions for how another system can call that agent or tool. Amazon Web Services said teams can use approval workflows and access controls before people or software agents are allowed to publish or use those entries. (docs.aws.amazon.com) An artificial intelligence agent is software that can plan steps and take actions with tools or data, not just answer prompts. Amazon Bedrock AgentCore is Amazon Web Services’ managed platform for deploying and operating those agents with permissions, monitoring, and security controls. (docs.aws.amazon.com) Large companies have spent the past year moving from chatbot pilots to fleets of specialized agents for software, security, and operations work. Amazon Web Services has been adding to that push: CIO Dive reported in December that the company introduced three “frontier agents” for development, security, and operations tasks. (ciodive.com) The registry is aimed at a basic enterprise problem: finding out which agent already exists, who owns it, and what it is allowed to touch. Amazon Web Services said both human users and software agents can search the catalog with semantic search, which matches meaning as well as keywords. (docs.aws.amazon.com) Amazon Web Services is also pitching the product as cloud-agnostic rather than locked to one hosting setup. The Register reported the registry is designed to work with agents hosted in AgentCore, other cloud services, or on-premises systems, and to support standards including Model Context Protocol and Agent-to-Agent. (theregister.com) Amazon Web Services is not alone in building a control layer for agents. Microsoft launched an Agent Store in May 2025 with more than 70 agents, and Google Cloud expanded a dedicated agent section in its marketplace in 2025, CIO Dive reported. (ciodive.com) That leaves Amazon Web Services selling not just more agents, but the filing system around them. As companies add more autonomous software, the harder question is no longer how to build an agent, but how to know what is already running. (aws.amazon.com)
