Walmart Opens MCP Agent Gateway While Amazon Locks Out AI Shopping Agents
sanjaykalra · x · 2026-10-22
As autonomous AI assistants begin purchasing directly for consumers, retail giants are splitting: Walmart embraces agentic commerce with an open Agent Gateway built on MCP, complete with Agent Profiles featuring spending caps and explicit return guarantees for agent errors — optimizing for inbound transaction volume and frictionless checkout. Amazon, by contrast, is locking its doors to third-party agents. The article argues this reflects fundamentally different philosophies about who controls the customer relationship, and weighs the pros and cons of each playbook: openness buys volume at the cost of control; closure protects the relationship but risks being bypassed.
