The Personal Agent Protocol is a proposed open standard for how a person’s AI agent interacts with a business. Announced by Meta and AI company Sierra on October 6, 2026, it is intended to help businesses recognize when an agent is acting for a customer, control what the agent can do and give users a say in what information they share. The first specification is still pending, so these are goals for a developing standard—not established protections already in effect. 1
What the protocol is intended to do
A personal AI agent can act on someone’s behalf online. For example, it might access an account or complete a task with a business. That creates a practical question for the business: is it interacting with the customer directly, or with software acting for them—and what should that software be allowed to do?
The proposed protocol is meant to provide common rules for authentication and access. Reports describe an OAuth-based approach through which a user could authorize an agent, while the business could decide which functions it makes available. An agent could connect through a company’s website, its APIs or the company’s own agent. 2
The intended balance is between user permission and business control: users decide what access to grant, and businesses decide what actions their systems expose to agents. The protocol is also meant to give businesses visibility into agent activity. 2
That design does not, by itself, prove that sensitive information will be protected or that an agent will act correctly. As of October 7, Sierra said a version 0.1 specification was planned for later in October; the detailed rules and their implementation were not yet available in the cited material. 1

Who is developing it—and who has joined?
Meta and Sierra are developing the standard with Genesys, Instinct, Rocket, Shopify, Stripe and Walmart. Sierra describes it as an open standard that others can implement.
The effort is led by Bret Taylor, Sierra’s co-founder and OpenAI’s chairman. That leadership role does not mean OpenAI is a protocol partner. OpenAI and Anthropic were not listed among the announced participants as of October 7, 2026. 4

Why Meta’s Muse makes the question timely
Meta launched Muse in September 2026 as a personal agent that can take actions for users, including sending emails, booking travel and selling a car. Those tasks can involve access to personal accounts and information. Reuters also reported concerns about how the agent might handle access to sensitive data.
That makes the protocol’s central problem relevant: businesses need a way to distinguish an authorized agent from an ordinary visitor and define what the agent may do. But the announcement does not establish that Muse already implements the protocol, or that the proposed standard resolves the concerns around sensitive data.
What to watch next
The key next step is the planned version 0.1 specification. Until its details are available, it is too early to assess exactly how permissions, business controls and activity visibility will work in practice. The protocol’s usefulness will also depend on implementation by businesses and agent providers; an open proposal alone does not ensure broad adoption or consistent safeguards. 1
