Summary
At an event in San Francisco, Walmart's CEO announced that the company is opening its systems to external AI agents to make purchases on customers' behalf, through "Agent Gateway" (based on Anthropic's MCP protocol) and "Agent Profiles", due the following month, with controls such as spending limits. Amazon has taken the opposite position: it blocked Meta's Muse agent, citing a breach of its terms of use, and has already restricted agents from Google and OpenAI and sued Perplexity over its Comet browser. The article highlights the economic stakes: Meta estimates that Muse has 10 million users and is considering monetising it through a percentage of purchases, a model Amazon refuses without an agreement.
