Personal Agent Protocol for Agentic Commerce
Major commerce and technology companies are developing an open protocol to help businesses authenticate personal AI agents and govern what they can do.
Overview
On October 6, Sierra announced the Personal Agent Protocol, an open standard being developed with Meta and partners including Genesys, Instinct, Rocket, Shopify, Stripe, and Walmart. The stated goal is to let consumers authorize personal agents while giving businesses visibility into agent activity and control over permitted actions. The protocol is intended to work through existing websites and APIs as well as company-operated agents. Its specification and reference implementation were still forthcoming as of October 11, so adoption and technical details remain unsettled.
