A good hotel doorman is the friendliest person on the street, and he does not work for you. He opens the door with a smile, remembers your name on the second visit and finds you a cab in the rain, but the people who pay him are inside the building, and everything he does at the door is a judgment about what you are worth to them once you are through it. The guest who will eat in the restaurant and drink at the bar gets the door held wide. The man who wants to cut through the lobby to the street behind it gets a polite question about whether he is staying with us. Nobody calls this rudeness. It is the job.
Every store on the internet is now hiring a doorman, because a new kind of visitor has started arriving: software sent by a customer to shop on that customer's behalf.
Two Doors on the Same Street
In September, Meta launched Muse, a personal AI agent that does ordinary online errands, shopping among them. Less than two weeks later, Amazon blocked it. People who asked Muse to buy something on Amazon began seeing a message that "continued access by an unauthorized AI agent violates Amazon's Conditions of Use, to which our customers have agreed." Amazon's complaint was specific: Meta never asked, the agent does not identify itself as it browses, and it appears to hold customers' credentials. Its spokesperson compared the situation to food delivery apps and travel sites, which take orders on a customer's behalf only with the restaurant's or the airline's agreement.
A month later, on the other side of the street, Walmart announced an Agent Gateway with Agent Profiles, so that customers can bring the agents they choose to Walmart and Sam's Club and decide what each one may do: set a spending limit, require approval before a purchase, or cut the agent off. Walmart already lists Muse among its integrations. It also wrote down a sentence that only a store expecting to be read by machines would bother to write: "We price products, not people, so the prices that an AI agent sees are the same prices that a human would see on Walmart.com."
Then Amazon's chief executive spoke to investors. Andy Jassy said on the October 29 call that few customers buy through outside shopping agents because the experience is "still not great, nor more convenient than coming to a retailer directly." In the same breath he reported that more than 400 million customers had used Amazon's own shopping assistant in the past year, and that U.S. customers who use it spend 50% more per order than those who do not.
So one doorman says the street is not ready for these visitors, and another builds them their own entrance with a guest list. Both are telling the truth about their own buildings.
The Door Follows the Money
The useful question is not which retailer is right about agents. It is what each one earns from the walk between the door and the till.
Amazon sells goods, and it also sells the walk. Its advertising business brought in $19.6 billion in the third quarter, and nearly all of that money is paid by brands to be seen by a person moving through a search page or down a product page on the way to buying something. An agent that arrives with an instruction to find the best price on a particular blender does not wander. It does not see the sponsored listing three rows down or the suggestion of a better blender at the bottom of the page, and a visitor who does not look at the shelves is a visitor whose attention cannot be sold. The analyst Neil Saunders put it plainly to Axios: Amazon is protecting a closed ecosystem and likely fears what agents could do to its advertising. Amazon's own assistant, meanwhile, walks the customer down Amazon's own aisles. The doorman lets in the guest who will use the bar.
Walmart's arithmetic runs the other way. A store whose promise is the everyday low price has every reason to welcome a visitor whose whole assignment is to compare prices, because the comparison is the argument it has been making for decades. When an agent can check every shelf on the street in a second, the store that wins on price wants to be on the list, and the controls it is building, the spending limits and approvals, are a way of telling the customer that letting software into the store is safe. It is still a doorman. He simply has a different idea of who will spend.
A door is a business model with a handle on it.
A Customer Who Does Not Look at the Shelves
For most companies reading this, the fight between Amazon and Meta is a long way from the work, and Jassy may well be right that buying by agent is early. Only 16% of shoppers are comfortable today letting an AI assistant find and buy products for them, according to Coveo research cited by Axios. But the early period is exactly when the doors get built, and two consequences arrive long before the agents are common.
The first is about where you sell. A brand that sells through retailers now depends on their door policies as well as their shelf space. If a meaningful share of your customers begin sending agents to do the comparing, the retailer that turns those agents away also turns away your products from that comparison, and the retailer that lets them in will show them whatever its catalog says about you. The second is about your own website, which is a store with a door of its own. Somebody in your company is already deciding, usually by default inside a security setting nobody in marketing has read, whether software acting for a customer can see your prices, read your specifications or complete a quote request. That is a commercial decision dressed up as a technical one.
Decide What Your Doorman Does
The decision deserves an owner and a written answer. If you earn from the sale and not from the walk, you probably want the door open to agents that identify themselves, with limits a customer can trust, and you want what they find inside to be specific: the real price, the real lead time, the real terms, stated in plain text that a machine can read without a sales call. If part of your value comes from the walk, a showroom, a consultation, a carefully built path through a site that persuades as it goes, then be honest that an agent will skip it, and decide what you will give the agent instead of pretending it will not arrive.
Either way, write the policy down before the visitors are common, because the store that waits will find that its door policy was set by whoever configured the firewall. The hotel always knew who the doorman worked for. The only stores that do not know are the ones that never asked.
