Sierra and Meta proposed an open standard for personal AI agents to sign in and act with businesses
Sierra and Meta announced the Personal Agent Protocol with Genesys, Instinct, Rocket, Shopify, Stripe and Walmart, an open standard for how a customer's AI agent interacts with a company. Sessions are built on OAuth: an agent can browse as a guest, and once the customer signs in they choose read-only or write access, with the session carrying across channels. Businesses choose whether agents reach them through the website, through APIs using MCP or OpenAPI, or through the company's own agent, and a v0.1 specification is due later in October.

Will clients need to support customers' AI agents on their websites?
Not yet for most small businesses, but clients that sell online should start planning for customer agents that check stock, book appointments or change orders on someone's behalf. The practical work is familiar: clean APIs, clear permission scopes and logging that shows when an agent rather than a person acted. Track this standard and the competing ones before advising any client to build for a single protocol.
