A consortium of major technology companies is developing an open standard to govern how personal artificial intelligence agents interact with businesses. Sierra, Meta, Genesys, Instinct, Rocket, Shopify, Stripe, and Walmart are collaborating on the Personal Agent Protocol, according to a blog post published Tuesday by Sierra Co-Founders Bret Taylor and Clay Bavor.
The specification, designated as version 0.1, is scheduled for publication by the end of October. The release will include a reference implementation designed to help developers integrate the new framework into their systems. This initiative aims to create a consistent method for connecting personal AI assistants with corporate digital infrastructure.
Authentication and Access Control
The protocol addresses critical security and operational challenges in the emerging field of AI-driven commerce. It defines how authentication occurs between a consumer’s personal agent and a business’s systems. The framework allows consumers to determine the level of access their agents have to their personal data and accounts.

Simultaneously, it provides companies with the ability to set boundaries on what their agents can do through websites, APIs, or dedicated company agents. This dual-layer approach seeks to balance user convenience with corporate security requirements.
“The company decides what it makes available, the personal agent gets a consistent way to connect, and the customer gets a faster way to get things done,” Taylor and Bavor wrote in their announcement. They emphasized that as personal agents take on more everyday tasks, companies need clear and secure methods to work with them while maintaining trusted experiences for users.
Industry Alignment and Market Context
Meta described the effort as an industry-wide alignment similar to the development of email standards. The company stated that agent commerce will be enabled by solving practical questions and reducing transaction friction. Meta highlighted the need to address how personal agents securely convey user identity and how businesses can steer these agents for efficient website use or toward optimized APIs.

The push for standardization comes as the market for personal AI agents expands rapidly. Meta launched its personal AI agent, Muse, on September 8. The application topped the App Store charts within days of its release, signaling strong consumer interest in AI-driven personal assistance.
Other players in the sector are also gaining significant traction. Instinct, the developer of a personal AI agent for everyday life, quadrupled its valuation to $10 billion in late September. Around the same time, OpenAI introduced Dots, a set of AI agents designed to handle a wide range of tasks.

The Personal Agent Protocol will be available for anyone to implement. This openness is intended to prevent fragmentation in the market and ensure that different AI systems can communicate effectively with various business platforms. The collaboration represents a significant step toward integrating AI assistants into the broader digital economy.
Sierra and Meta will continue to work with their partners to refine the protocol. The goal is to establish a foundation that allows companies and personal agents to complete tasks for customers efficiently and securely.
