AI Agent Registration Protocol AgentID Approved by W3C: Autonomous AI Agents Get Standard Network Identity for the First Time

AI Agent Registration Protocol AgentID Approved by W3C

On March 11, 2029, the World Wide Web Consortium (W3C) formally released the AgentID standard, defining a unified identity specification, capability declaration, and behavior audit framework for AI agents operating autonomously on the internet. This means AI agents have for the first time been given a standard network identity system parallel to human users and domain names.

The AgentID standard defines a new URI format: agent://domain/agent-name. Each AI agent must declare its parent organization, capability scope, data access permissions, and code of conduct at registration. All AgentID-registered agents must maintain tamper-proof audit logs recording all their interactions on the internet.

W3C AgentID working group co-chair and Mozilla Foundation researcher Jeni Tennison said: "AI agents are flooding onto the internet — they search for information, send emails, book services, and conduct transactions. Without a standard identity framework, we cannot distinguish a trustworthy AI assistant from a malicious scraper."

Google DeepMind, OpenAI, and Anthropic have announced support for the AgentID standard and will integrate AgentID registration into their respective AI agent platforms. Amazon AWS has also indicated it will offer one-click AgentID registration for agents hosted on its cloud.

However, critics worry that AgentID could evolve into a digital fence — where only registered AI agents can legally access internet resources — which could be used by large companies as a tool to exclude competitors and small-scale AI developers. EFF senior researcher Bennett Cyphers said: "We need to ensure that AgentID doesn't become a licensing regime for internet access."
