Walmart will let AI agents shop on its site

Starting next month, Walmart will let customers connect their own AI agents to shop on its website, with purchase approvals and spending limits. Agents connect through an Agent Gateway built on the Model Context Protocol and must follow Walmart's terms. Amazon, by contrast, blocks third-party AI shopping agents.

• Agent purchases require approval by default, with optional budgets like $100
• Agents connect via an Agent Gateway built on the open MCP standard
• Agents cannot change payment methods or act beyond the shopper's intent
• Agent purchases appear separately in Agent Profiles and can be disabled anytime
