What happens when your customer's AI agent shows up at your business before your customer does?
It's about to be a normal Tuesday.
Yesterday, Sierra and Meta announced Personal Agent Protocol, an open standard for how a person's AI agent signs in to a business and what that business lets it do. Walmart, Shopify and Stripe are founding partners, along with Genesys, Rocket and Instinct. The first spec is due later this month.
Here is how it works in plain terms.
The agent arrives as a guest. It can check stock or read your returns policy. Once the customer signs in, the customer decides whether the agent gets read-only access or the right to make changes. Then you decide how it gets served: through your website, through your systems, or through an agent of your own.
Two things are worth knowing. Payments aren't in the first version. And Amazon, OpenAI and Anthropic aren't on the partner list. So this is one standard among competing ones, not the finish line.
That's not the point.
The point is that the big names have stopped debating whether customers will send agents. They're writing the rules for the front door.
Most agents today use your website the way a person does. They load pages and click through forms. When that fails, they call your support line or open your chat. If your answers live in someone's head, or in a PDF nobody updated, the agent hits a wall and your customer goes to the competitor whose answers were easy to read.
You don't need a protocol to get ready. You need three things written down in plain language: what you sell, what it costs, and what happens when something goes wrong.
Agents will be reading that before your customers do.
If an AI agent walked into your business today and asked for your pricing, your hours and your return policy, could it get a clear answer in ten seconds?
