Amazon has blocked Meta’s Muse AI agent from shopping on its marketplace on behalf of users. Muse now displays a message saying that access by an unauthorized agent violates the conditions Amazon customers accept when using the store.
Meta did not notify Amazon before Muse began accessing the site, according to GeekWire’s reporting cited by The Verge. Amazon also raised concerns that the agent did not identify itself while browsing and appeared to capture customer credentials. Meta said at Muse’s launch that the assistant cannot see secure login details or payment-card information, and had not provided a response to the new report when the article was published.
The block follows wider privacy questions about Muse, including reports that it could read user messages without the corresponding permission enabled. During earlier testing, The Verge successfully used the agent to purchase clothing from Amazon, showing that its access had extended beyond product search into completed transactions.
Amazon says third-party applications making purchases should operate openly and respect a retailer’s decision about participation. The company previously sued Perplexity over similar shopping access, although a judge sided with Perplexity. The latest dispute leaves users caught between delegated convenience and platform control: an agent may have its owner’s permission, yet still lack permission from the service it is automating.
