Walmart Launches Proprietary AI Agent Gateway for Automated Shopping

Walmart has launched a proprietary AI agent gateway using the Model Context Protocol (MCP) to allow authorized AI agents to check inventory and place orders on behalf of users. Additionally, the retailer introduced agent profiles and permission controls to let customers set spending limits and review agent-generated transactions. This development marks a stark contrast to competitors like Amazon and travel booking sites that are actively blocking AI agents, positioning Walmart as an early adopter of agentic commerce. By establishing clear guardrails and standardizing interactions via MCP, Walmart is opening up new revenue channels while addressing consumer privacy and safety concerns. The gateway prevents AI agents from accessing user payment information, and Walmart's standard return policy still applies even if an agent makes an error. Users can create individual authorization profiles for each AI agent, requiring manual confirmations or automated approvals within a set budget.
