Walmart Agent Gateway: an MCP server for AI shopping agents
Walmart launched an MCP server called Agent Gateway, live with ChatGPT, Gemini and Meta's Muse, letting approved agents search inventory and buy without seeing payment details.
AI shopping agents just got a front door at Walmart. While Amazon blocks agents, Walmart announced an MCP server called Agent Gateway: → Approved agents can search Walmart and Sam's Club inventory and buy for you → You don't have to share personal info or purchase history with the agent → Next month: a separate profile per agent in your account → Require approval per purchase, or pre-approve up to a spending limit The rules: agents can't see payment details, can't act beyond what you asked, and get blocked if they break the terms. Walmart's returns policy still applies if an agent gets it wrong. It already works with Meta's Muse, ChatGPT and Gemini. https://techcrunch.com/2026/10/21/while-amazon-blocks-ai-agents-walmart-rolls-out-the-welcome-mat/
