Meta and Sierra announced joint development of the Personal Agent Protocol, with the v0.1 specification planned for release this month

Meta and Sierra, together with Genesys, Instinct, Rocket, Shopify, Stripe, Walmart, and other companies, are developing an open standard called the Personal Agent Protocol to define how personal AI agents interact with businesses. The protocol uses OAuth for identity authentication, letting consumers decide whether to grant agents read-only or write permissions, while businesses can set the scope of actions agents may perform through their websites, APIs (such as MCP, OpenAPI), or their own agents. The v0.1 specification is planned for release later this month, along with a reference implementation.
