Amazon cut off Meta’s Muse AI agent from shopping on Amazon.com. It cited data security and lack of consent. Muse does not identify itself when browsing Amazon. Amazon says Muse captures and stores customer credentials. Users now see a popup blocking access. Amazon wants Meta to remove Amazon from Muse’s experience. Both companies are business partners in other areas. The move is part of a broader industry fight over agentic shopping control. Amazon has previously blocked agents from Google and OpenAI. Legal action remains a possibility.
