Meta, Walmart, Stripe and Sierra back Personal Agent Protocol for AI shopping agents

Meta, Walmart, Stripe and Sierra Technologies are partnering on a Personal Agent Protocol that would define how AI agents interact with businesses online. Sierra co-founder Bret Taylor said it will handle authentication and give companies visibility into personal agents' activity, and it is open for anyone to implement. The effort responds to concerns from six major banks, which urged the industry last month to set standards around transparency, safety, privacy, choice and interoperability.
