Walmart’s next move in online retail is to let AI agents into the store — but only through a tightly controlled front door. The retailer said its new Agent Gateway will allow approved agents to search its inventory and purchase items for customers, with support also planned for Sam’s Club.¹

The Gateway uses the Model Context Protocol, a standard designed to connect AI systems with outside tools and services. Rather than hand an agent a shopper’s full account history, Walmart says it can help the agent identify familiar purchases — such as a usual bread or milk brand — without exposing broader personal information.¹

The consumer pitch is control. Beginning next month, shoppers will create separate Agent Profiles for each AI service, review those purchases apart from their own, require approval transaction by transaction, or authorize spending up to a chosen limit. Profiles can be deleted, and agents that violate Walmart’s rules can be blocked.²

Those rules draw a clear line: agents “must not take actions beyond what the shopper intends,” cannot alter payment methods, and may access only the data needed for the task.¹ Walmart also says its normal returns process will apply when an agent gets a purchase wrong — an important reassurance for shoppers wary of giving software buying power.²

The launch lands amid a broader fight over who controls AI-driven commerce. Amazon has moved to block shopping agents, including Perplexity’s tool and Meta’s Muse assistant, while Walmart has already partnered with Muse and integrated with services including ChatGPT and Gemini.²

The convenience case is already being advertised in the AI world.
