> Meta, Sierra, Shopify, Stripe, Walmart and others are building an open standard for how your personal AI agent signs in to a company and gets things done, without pretending to be you clicking through web forms.

Personal AI agents can now book a table, change a flight or shop for car insurance. Mostly, they do it the awkward way: loading web pages and clicking through forms like a very patient human, or calling a support line. On 6 October, the customer service AI company Sierra and Meta announced an open standard meant to replace that with a proper front door.

## How it works

The Personal Agent Protocol, developed with Genesys, Instinct, Rocket, Shopify, Stripe and Walmart, starts on a company’s website, where an agent can discover what the company offers and how to reach it. The agent then opens a session for its user:

**As a guest,** which may be enough to check stock or ask about a returns policy.

**Signed in,** when a task needs the customer’s account. The customer signs in on the company’s page, or uses credentials already set up with their agent, and decides whether the agent gets read-only or write access.

Sessions are built on OAuth, the standard behind “sign in with” buttons, and carry across channels, so a question asked as a guest and an order changed later are part of one visit. The company then chooses the route: its normal website, its APIs (using standards such as MCP and OpenAPI) or its own customer service agent.

## What it is, and is not, yet

Today it is an announcement, not a finished standard. The partners plan to publish a v0.1 specification later in October, hold design workshops and release a reference implementation. Payments, push notifications and finer-grained permissions are listed as possible future extensions.

**Why it matters:** agents that identify themselves and ask for scoped permission are better for everyone than agents that impersonate a person in a browser. Businesses get visibility, customers get control, and websites get fewer mysterious bots. Whether it becomes the standard depends on who else joins.
