Meta, Walmart, Stripe, and the startup Sierra have launched the Personal Agent Protocol. This open standard aims to regulate how AI agents interact with businesses and verify their identity. Bret Taylor, OpenAI chairman and co-founder of Sierra, is leading the initiative to address security concerns regarding unauthorized bot access to corporate services.
The protocol is designed to distinguish between human users and AI agents, providing businesses with visibility into agent activities. David Singleton, VP of Engineering at Meta’s Reality Labs, compared the standard to email, suggesting it will create a reliable framework for communication between agents and enterprises. The developers hope this will streamline tasks like booking appointments or making purchases.
The initiative follows the rapid growth of Meta’s Muse agent, which has reached millions of users in the US since its launch in early September. Despite its popularity, some companies, including Amazon, have blocked Muse and other AI agents over concerns regarding web scraping. Amazon has also filed a lawsuit against Perplexity regarding its scraping practices.
While major AI developers like OpenAI and Anthropic have not yet joined the protocol, Bret Taylor stated that he expects them to participate in the future. The organizers emphasize that the standard is necessary to manage the risks associated with autonomous agents accessing sensitive personal and financial information.
