Walmart Opens the Door to AI Shopping Agents as Amazon Tightens the Gate

Walmart is taking a different path from Amazon in the fast-emerging world of AI-powered shopping. On Wednesday, the retailer announced new tools, including an Agent Gateway and customer controls for approved AI agents, designed to let software agents shop, search inventory and complete purchases on behalf of customers.

The move matters because it positions Walmart as one of the first major retailers to actively accommodate agentic commerce at scale, even as rivals such as Amazon move to block outside AI agents from making purchases for shoppers.

Walmart’s announcement adds another sign that the retail industry is splitting into two camps: companies trying to control how AI agents interact with their systems, and companies preparing for a future where consumers increasingly delegate routine shopping tasks to software.

What Walmart announced

Walmart said it is rolling out a set of systems intended to make AI-assisted shopping safer, more transparent and easier to manage for customers. The centerpiece is Agent Gateway, a new MCP server that allows approved AI agents to connect with Walmart’s systems through the model context protocol, or MCP.

That protocol, developed by Anthropic, has become an important bridge between AI assistants and outside tools. In practical terms, it lets an agent query products, inspect inventory and, if authorized, place orders on a customer’s behalf.

Walmart is pairing that infrastructure with customer-facing controls that separate agent-driven purchases from those made directly by the shopper. The company says the system is intended to give customers more visibility and more say over what AI tools can do.

Why does this matter for online retail?

This matters because AI agents are moving from novelty to transaction layer. If consumers begin using agents to find products, reorder staples and compare prices, retailers will need rules for access, identity, permissions and payment handling.

Walmart is effectively building a framework for that future rather than waiting for it to arrive on its own. That approach stands in contrast to the defensive posture many businesses have taken as AI traffic begins to hit their sites.

How Walmart’s Agent Gateway works

Walmart’s Agent Gateway is built around a simple idea: let approved agents interact with the retailer in a controlled way, rather than forcing them to mimic a human shopper in a browser. The retailer says agents can use the gateway to search inventory and complete purchases for users who have granted permission.

The company also says the gateway is designed to limit the information that agents can see. Walmart says agents will only receive the data needed for the specific shopping task, rather than broad access to customer records or purchase histories.

That narrower access is meant to reduce privacy concerns and lower the risk that an agent sees more than it should.

What are Agent Profiles?

Agent Profiles are Walmart’s answer to one of the biggest problems in agentic commerce: attribution. If an AI assistant makes a purchase, shoppers need a way to identify that transaction separately from their own.

Walmart says customers will be able to create a dedicated profile for each AI agent they use through the Agent Gateway. Those profiles will make it easier to track purchases made by a specific assistant, review activity and remove access later if needed.

The profiles will begin rolling out next month. When a shopper uses a given agent for the first time, Walmart will create the profile and ask the customer to link it to their account. From there, the customer can set spending limits or require approval for every purchase.

Walmart said the controls are similar to adding an authorized user to a credit card account: the user can make purchases, but those purchases remain visible and can be governed by rules set by the primary account holder.

How much control will customers have?

Customers will have direct control over approval settings, spending caps and revocation. Walmart says a user can decide whether every transaction requires confirmation or whether the agent may buy within a preset limit.

Customers can also delete an Agent Profile at any time, which gives them a practical off switch if they no longer want a particular tool shopping on their behalf.

Importantly, support for these features is available to any Walmart account holder, not just Walmart+ subscribers. That means the company is aiming for broad adoption rather than making agentic shopping a premium perk.

Why Walmart is embracing AI agents while Amazon is blocking them

Walmart’s strategy is notable because it comes just as Amazon has begun taking the opposite approach. Amazon has started blocking AI agents from making purchases on behalf of online shoppers, a move that signals concern about control, site integrity and the broader implications of outside software acting like a customer.

Other major businesses, especially travel and booking platforms, have also moved to lock AI agents out entirely. Their concern is that agents can disrupt established purchasing flows, scrape data, create security issues or bypass the site experiences those companies have designed.

Walmart, by contrast, is trying to define the rules of engagement. Rather than shut the door, the retailer is setting conditions for what approved agents can and cannot do.

Walmart’s leadership has framed the rollout as preparation for a future in which AI agents are a normal part of shopping, with the company building the infrastructure now so it can support that behavior safely and at scale.

The decision also reflects a strategic bet. If consumers come to trust their agents to manage recurring purchases, the retailers that welcome those tools may gain a customer-service advantage over those that resist them.

What protections did Walmart build in?

Walmart says it has added rules that govern how agents may behave on its site. Those terms are meant to protect both shoppers and the retailer if an agent makes an unintended choice or acts outside the customer’s instructions.

The company says agents cannot take actions beyond the customer’s intent, cannot access payment information directly and can only use the information required for the task at hand. If an agent does not comply with the rules, Walmart says it will be blocked from accessing the site.

That enforcement layer is important because it shows Walmart is treating agent traffic as a managed category, not an open invitation. The company is essentially creating a permissioned ecosystem for software shoppers.

What happens if an agent buys the wrong item?

Walmart says its standard returns process still applies, even if an AI agent misfires and purchases something the shopper did not intend to buy. That policy could matter a great deal to hesitant consumers who worry that an autonomous assistant might make mistakes.

The returns policy lowers the perceived risk of trying agentic shopping. For a category that depends on trust, that may be one of the most important signals in the entire announcement.

How this fits into Walmart’s broader AI strategy

Walmart has not been treating AI as a side project. The company has already said it works with a range of AI apps, including ChatGPT and Gemini, and it has partnered with Meta’s Muse in the agent space.

Wednesday’s announcement extends that strategy from partnerships into infrastructure. Instead of relying only on outside platforms to shape the shopping experience, Walmart is building the technical plumbing that determines how those tools connect to its business.

That is a meaningful shift. Retailers that once focused on mobile apps and loyalty programs are now being pushed to think about identity, interoperability and machine-to-machine commerce.

Walmart is also covering both of its core retail businesses: the main Walmart brand and Sam’s Club. That broadens the rollout beyond ordinary e-commerce and into warehouse-club replenishment, where repeat orders and predictable buying patterns could be especially well suited to agentic commerce.

Why model context protocol matters

Model context protocol, or MCP, is emerging as one of the key standards for connecting AI models to the outside world. It gives agents a structured way to talk to databases, tools and services without each integration requiring a custom one-off build.

For retailers, that matters because it could make AI integrations more scalable. A retailer can expose selected actions and data through a protocol instead of building bespoke links for every model or assistant.

Walmart’s use of MCP also signals that the company sees interoperability as a feature, not a threat. By adopting a standardized interface, it is making itself easier for approved agents to work with while still retaining control over what they can do.

The protocol’s creator, Anthropic, has helped popularize MCP as a framework for building agent-friendly software ecosystems. Walmart’s adoption adds another high-profile example of how the standard may be used in commerce rather than only in general-purpose AI applications.

What this means for shoppers

For customers, the short-term impact is likely to be modest but practical. Shoppers who already use AI assistants to compare products or remember recurring purchases may soon find a more official path to complete those tasks at Walmart.

Over time, the bigger change could be behavioral. If consumers become comfortable authorizing agents to restock household items, manage price checks or handle routine purchases, the shopping experience may shift from browsing and clicking to instructing and approving.

That could be especially useful for time-pressed customers buying the same brands or staples week after week. Walmart says its gateway can help shoppers purchase usual items without revealing personal information or detailed purchase history to the agent, which may also make the process feel safer.

• AI agents can search Walmart inventory and complete purchases with permission.
• Customers can set spending limits or require per-transaction approval.
• Each agent gets its own profile to separate its purchases from the shopper’s.
• Walmart says agents cannot access payment information directly.
• Returns still apply if an agent buys the wrong item.

What this means for competitors

Walmart’s approach may put pressure on other retailers to clarify their own agent policies. If one of the world’s largest retailers is offering a structured path for AI shopping, competitors may face questions about whether blocking agents is a long-term strategy or simply a temporary defense.

There is also a branding element. A retailer that welcomes AI agents can present itself as innovative and customer-friendly, while a retailer that blocks them may appear cautious or restrictive. That perception could matter as consumers grow more familiar with the technology.

At the same time, companies have good reasons to be careful. Agent traffic introduces concerns about fraud, scraping, broken site flows and customer support complications. Walmart’s announcement suggests it believes those concerns can be managed with rules, identity controls and narrow permissions.

Timeline: How the rollout is unfolding

Walmart’s announcement is not a single switch flip. The company is rolling out the pieces in stages, with some capabilities available now and others arriving next month.

What comes next for agentic commerce?

Agentic commerce is still early, but the direction is clear: more consumers will rely on AI assistants to research, compare and possibly purchase products. The open question is which companies will build the rails for that behavior and which will try to stop it.

Walmart’s answer is to regulate access instead of refusing it. By combining technical controls, user permissions and policy enforcement, the retailer is trying to make AI shopping feel like a normal part of retail rather than an experiment conducted at the customer’s risk.

If that model works, it could become a template for other businesses that want the benefits of AI-assisted commerce without surrendering control of their platforms.

For now, the contrast with Amazon is striking. One retailer is locking the door; the other is issuing rules, profiles and a gateway key. That difference may shape how the next generation of online shopping is built.

As AI agents become more capable and more widely used, the companies that succeed may be the ones that design for them early, not the ones that wait to see whether the trend disappears. Walmart is clearly betting that the future of retail will include software shoppers — and that it is better to be ready than to be surprised.
