Sierra and Meta propose Personal Agent Protocol, an open standard for personal SI agents to access company services
Prepared by Sintelligent with the help of SI. Publication time restored from the build log. . Updated: .
Agents need "passports" and rules for entering websites: several competing standards are emerging, and the winner will be the one commerce follows.
The OAuth-based protocol defines how a personal agent authenticates itself to a business and what permissions it gets (guest, read-only or write), and how the company sees its actions on its site. Businesses choose for themselves whether to admit agents through the website, an API (MCP, OpenAPI) or their own agent systems. Sierra and Meta lead the development, with partners including Genesys, Instinct, Rocket, Shopify, Stripe and Walmart; payments are deferred to a future extension for now, and version 0.1 of the specification was promised by the end of the month. Stripe and Shopify were already part of Visa's competing Trusted Agent Protocol.
