Walmart invites AI agents to shop on its site, with guardrails

Walmart will allow AI agents on its site next month, with approval, spending limits and an Agent Gateway. The move contrasts with Amazon’s block on similar tools.

What happened

Walmart says it will soon let AI agents shop on its website. Next month, the retailer will allow a customer to use an AI agent on the site, with systems to approve and review purchases and set spending limits.

The approach differs from Amazon, which blocked Perplexity’s shopping agent and Meta’s Muse AI assistant. Walmart is instead letting AI shoppers in under terms: agents must not take actions beyond what the shopper intends, cannot change a customer’s payment method, and can only access information needed to complete a task. Walmart says it will block agents that do not follow those terms.

Agents will connect to new Agent Profiles within Walmart. By default, Walmart will require approval for all AI agent purchases, but shoppers can also let an agent shop within a budget, such as up to $100. Purchases made by the agent can be reviewed separately from the customer’s own purchases, and the agent can be turned off at any time. Walmart has also built an Agent Gateway, now in beta, that connects AI agents through the Model Context Protocol, an open standard for plugging AI into web services. Walmart says this reduces browser-based hiccups and prevents agents from accessing shopping history and personal information.

“For example, if a customer tends to buy sourdough bread or a particular brand of milk, Walmart will help the agent find those usual items for the customer without sharing the customer’s broader shopping history with the agent,” Walmart says.

The company will let users shop with AI agents on Sam’s Club as well.

Key facts

• Walmart will allow AI agents to shop on its website next month, with approval and review systems.
• Spending limits can be set; the source cites the example of up to $100.
• Amazon blocked Perplexity’s shopping agent and Meta’s Muse AI assistant.
• Walmart’s terms say agents cannot go beyond shopper intent or change a customer’s payment method.
• Agent Gateway, currently in beta, connects agents through the Model Context Protocol and prevents access to shopping history and personal information.

Our analysis

The most consequential detail is not that Walmart accepts AI agents; it is that Walmart is setting platform-level rules for them. The reported terms create a permission layer around payment, data access and intent. That suggests Walmart is trying to make AI shopping agents behave like managed sub-accounts rather than free-roaming browser scripts. For brand operators, this likely means product visibility may increasingly depend on how an agent interprets a shopper’s stated budget and preferences, rather than only on search ranking or display ads.

Walmart’s Agent Gateway is also important because it uses the Model Context Protocol, an open standard. If that becomes the default handshake for commerce agents, creators and operators may need to think about how their product data is exposed to agents. The example about sourdough bread and a particular brand of milk suggests Walmart can match habitual purchases without sharing broader shopping history. That is a privacy-preserving signal: the platform may help agents find usual items while restricting the personal data agents can see.

The contrast with Amazon is notable. Walmart’s move suggests a bet that controlled AI shopping can increase purchase frequency or basket size without surrendering customer trust. That is not guaranteed, but the approval default and separate review flow show Walmart is starting cautiously.

What it means for operators

• Review product data and listing copy for machine readability. If agents are nudged toward “usual items,” clear product attributes and consistent naming likely matter more.
• Treat agent-mediated purchases as a new touchpoint. Track whether your commerce platform or landing pages can surface in agent-driven shopping flows, and ask partners how they handle agent access.
• Do not assume open access. Walmart’s rules show agents may be blocked for overstepping intent or touching payment methods; similar restrictions could appear on other platforms.
• Watch Agent Gateway and Model Context Protocol adoption. If open agent standards spread, early preparation can help brands appear in agent-driven shopping without needing custom integrations.
