Meta, Sierra and partners including Genesys, Instinct, Rocket, Shopify, Stripe and Walmart launched the Personal Agent Protocol on October 7, 2026, to set rules for how personal AI agents interact with businesses. The early specification is intended to address authentication, visibility into agents’ activity on websites and APIs, and security as agents take on tasks delegated by people. Sierra said consumers want speed, dependability and trust, brands want visibility and control, and companies want efficiency and access. The protocol is designed to let agents such as Meta’s Muse work with businesses.

The protocol’s specification is at an early stage, and the article says it could develop quickly, as the Model Context Protocol did. Shopify, Stripe and Walmart are partners because shopping is expected to account for many tasks handled by personal agents. Rocket’s participation may relate to agents completing mortgage tasks delegated by customers, while Genesys and Sierra are focused on customer service and visibility. Walmart, Shopify and Stripe are pursuing commerce uses; the article raises questions about sales and how disputes would be handled.

Meta says Muse applies two tests before acting: whether a reasonable person would take the action, such as creating five accounts to redeem one coupon, and whether systems could withstand every agent taking that action. The author calls the tests interesting but doubts they will hold up, arguing that Muse may eventually act because it can, as people do.
