Meta, Walmart and Stripe build standard for AI agents

Meta, Walmart, Stripe and Bret Taylor's startup Sierra are publishing an open "personal agent protocol" to standardize how AI bots interact with businesses. Taylor, OpenAI's chairman, leads the effort; Amazon has already blocked agents from Meta and Perplexity.

• The standard defines how AI agents access companies' services
• Meta's Muse agent tops the App Store with millions of US users
• Amazon blocked Meta and Perplexity agents and sued Perplexity
• OpenAI and Anthropic are not yet on board, Taylor expects them to join
