What Changed
Amazon has blocked Muse: the agent can no longer make purchases in the store on behalf of users.
On Sunday, Muse users saw a notification stating that continued access by an unauthorized AI agent violates Amazon's terms of use. According to GeekWire, Meta did not notify Amazon in advance that the agent was working with the store.
Why Amazon Restricted Access
Amazon raised concerns about privacy and security. According to The Verge, Muse does not identify itself when browsing the site and is reportedly obtaining shoppers' credentials.
An Amazon spokesperson told GeekWire that third-party apps must clearly identify themselves and respect services' decisions about whether to allow such apps. When it comes to working with a store, an agent needs not only the technical ability but also the service's permission.
Meta's Claims and Test Results
Meta said that Muse cannot see protected login data or card payment information. However, during testing by The Verge, the agent successfully bought T-shirts on Amazon while other items were in the cart.

After the launch, concerns arose about access to personal information. Reports claimed that Muse could see the contents of users' messages even when the necessary permission was disabled.
What to Consider When Choosing AI Shopping
This case shows that an agent's capabilities also depend on a store's rules. Amazon cut off Muse's access, citing its terms of use and its decision not to allow unauthorized agents.
When evaluating similar use cases, three criteria matter: whether the store allows agents to operate, whether the agent identifies itself, and what data it can see. These questions help distinguish advertised features from the conditions of actual access.
