Walmart launches Agent Gateway as Amazon blocks AI bots

Walmart is opening its checkout to AI shopping agents. The retailer on Wednesday launched its Agent Gateway, a model context protocol (MCP) server that lets approved bots search its online inventory and complete purchases on behalf of customers, even as chief rival Amazon blocks the same traffic.

The gateway covers both Walmart and Sam's Club, and the company says any account holder can use it — no Walmart+ membership required. Agent Profiles, the customer-facing control layer, go live next month.

Walmart President and CEO John Furner unveiled the push at the Masters of Scale Summit in San Francisco, framing it as preparation for a moment when AI agents move from novelty to default. Furner said the gateway expands on earlier efforts to get ready for a world where AI agents become mainstream.

How does Walmart's Agent Gateway work?

The gateway is Walmart's first MCP server, built on the open protocol created by Anthropic. MCP lets AI agents talk to external data, tools, and workflows. In Walmart's case, an approved agent can browse the retailer's catalog, check prices, and place orders while the human shopper stays out of the loop.

Walmart says it has already wired the system to leading consumer AI apps. A previously announced partnership with Meta's Muse is live, alongside integrations with OpenAI's ChatGPT and Google's Gemini. Travelers, by contrast, are running into walls: airlines, hotels, and booking sites have begun blocking agent traffic outright as adoption has accelerated.

What are Agent Profiles?

Agent Profiles are Walmart's answer to a problem every bank and credit card issuer solved decades ago: how to let someone else spend your money without handing over the keys. Each AI agent a customer uses gets its own profile, linked to the shopper's Walmart account, and its purchases show up as a separate line in the order history.

Customers set the rules. They can require approval on every transaction or pre-authorize purchases up to a self-set spending cap — a structure Walmart compares to adding an authorized user to a credit card. Profiles are created the first time a given agent shops through the gateway, and customers can delete them at any time. The first wave lands next month.

What rules do AI agents have to follow?

Walmart has published binding terms of service for any agent that wants to transact. Three conditions stand out.

First, agents cannot exceed the shopper's stated intent. Second, agents cannot touch the customer's payment credentials. Third, agents get only the data they need for the task at hand — no broader purchase history, no stored personal details.

Agents that break the rules get blocked from Walmart's site. And crucially, Walmart's standard returns policy covers purchases made by an agent that misbehaves. The retailer is essentially absorbing the risk that a bot orders the wrong size, the wrong brand, or the wrong product altogether — a customer-friendly stance aimed at nervous early adopters.

Where does this leave Amazon?

Amazon has moved in the opposite direction, recently starting to block AI agents from completing purchases on its marketplace. Walmart's bet is that the retailer that learns to work with agents first wins the next decade of digital commerce. The infrastructure is the bet: an MCP server, an agent profile system, a published rulebook, and a returns guarantee.

The risk is that Walmart hands margin to bot operators, software middlemen, and the AI platforms that already own consumer attention. If ChatGPT, Gemini, or Meta's Muse becomes the front door to Walmart, the retailer is back to paying for traffic it once owned.

For now, Walmart is moving while Amazon holds the door shut, and the first quarter of agentic commerce will show which stance shoppers — and their bots — actually prefer.
