Meta and Sierra are developing Personal Agent Protocol to give customer AI agents a more consistent way to interact with businesses. Their 6 October announcement names Genesys, Instinct, Rocket, Shopify, Stripe and Walmart as partners. The first specification is planned for later this month.

The customer grants access; the business sets the routes
Sierra’s proposed design starts on a business website. An agent could check public information as a guest, then use a customer-authorised session for account-specific tasks. Customers would choose read or write access; businesses would decide which websites, APIs or company agents they expose. The session design uses OAuth, the established framework for granting access.
Sierra announces the protocol-development effort and its industry partners.

Stripe’s original quote-post confirms its role in the effort. Sierra plans a v0.1 specification, design workshops and a reference implementation. Payments extensions and more detailed permissions are possibilities for future work. The announcement does not establish a production rollout or a European availability date.
A broader customer connection than checkout alone
The commercial question is how a brand recognises a customer’s agent and controls what it can do. Shopify’s browser checkout tools already address a narrower task; this proposal reaches toward service interactions across channels. That distinction will become easier to assess when the specification is published.
