Sierra and Meta propose Personal Agent Protocol, an OAuth-based standard for personal agents to sign in to businesses

Announced Oct 6 with Genesys, Instinct, Rocket, Shopify, Stripe, and Walmart, the open standard lets a personal agent start as a guest on a company's site, then sign in with read-only or write access the user picks, and finish the job through the website, MCP or OpenAPI endpoints, or the company's own agent in one OAuth session. The v0.1 spec and a reference implementation are due later in October, so nothing is implementable yet.
