Amazon blocks Muse: Meta’s AI agent can no longer shop the store

Amazon blocks Muse, Meta’s personal AI agent, from browsing and buying on its marketplace. Users see a warning that unauthorized agent access violates the conditions of use.

What happened?

Muse launched in the U.S. in early September 2026 as an app that compares products and, with user approval, places orders. An Amazon spokesperson told GeekWire, the Washington Post and TechSpot that the retailer asked Meta to drop Amazon from the experience. Meta declined. The block began Sunday night, September 21, U.S. time.

Amazon says it was not told Muse would hit the store, that the agent does not identify as a bot, and that it appears to capture credentials and account data. Meta said at launch that Muse has no direct access to passwords or payment methods.

Why it matters

It is an early public fight of the agentic-commerce era: who owns the checkout when a third-party assistant acts for the customer. Amazon likens the rule to food-delivery and travel apps that need merchant opt-in. It also signaled the same stance toward Google and OpenAI agents.

Legal backdrop: Amazon sued Perplexity over shopping agents, won a preliminary injunction in March, then lost it on August 4 when the Ninth Circuit said the user — not the AI firm — is the one accessing the site.

In practice

Muse can no longer complete Amazon orders. The app still topped free charts on Apple and Google at launch, and Meta shares rose more than 11% the next session, Axios reported.
