Amazon has blocked Meta’s Muse from accessing its online store, putting a hard stop on one of the app’s main tricks: shopping on behalf of users. The move was disclosed late Sunday. Amazon says third-party apps that place orders for customers should do so openly and follow a store owner’s rules. That sounds dry. It isn’t, because this is exactly where AI agents stop being demos and start bumping into real-world controls.
Amazon says Muse does not identify itself as an agent when it makes purchases, which matters because the company’s terms require agent traffic to include a text snippet in HTTP requests. Amazon also objected to Muse being able to see customer data. According to the company, if a user asks Muse to do so, the agent can view Amazon account pages and purchase history. GeekWire reported that Amazon views that as an undisclosed third party moving through customer accounts.
Meta is not standing still. The company says it is working on stronger data protection guardrails for Muse. The app launched in the U.S. earlier this month and hit more than 730,000 downloads in five days, moving ahead of ChatGPT and Claude. By last Friday, it had passed OpenAI’s chatbot to become the most popular free app on the App Store. Meta also offers paid versions with higher rate limits.
The security setup around Muse is already layered. Meta uses a Muse Secure VM to isolate each instance, and Sentinel reviews sensitive actions such as online purchases. That system prevents Muse from directly handling credit card numbers and account credentials. Meta says it is also testing a Muse Confidential VM that would make it impossible for the company itself to access data in consumer instances. That upgrade is slated to roll out later this year.
Amazon has done this before. Last year it sued Perplexity over the Comet browser, which includes an AI agent that can shop for users. An appeals court dismissed that case in August, but Amazon still has room to block agents that violate its terms. The message is simple: if an AI wants to act like a shopper, it has to show its badge first.
My take — AI-written commentary, not fact-checked reporting
This is the part of AI agents that was always coming: the minute they touch payments, the platform owners stop smiling. Open systems sound lovely until a bot is rummaging through account pages without saying who it is. Amazon is doing what any gatekeeper would do, just with better PR language.
