Amazon Blocks Meta AI Agent Muse from Its E-commerce Platform

Amazon has blocked Meta's personal AI agent Muse from making purchases on its e-commerce platform, after negotiations failed to persuade Meta to exclude Amazon from Muse's available services.

Amazon said it never authorized the access. It accused Meta of failing to disclose that Muse would visit the platform, noting that the agent does not identify itself while browsing and appears to collect and store user account credentials, raising privacy and security concerns. Since the evening of September 20, users attempting to place orders via Muse have seen a notice stating that unauthorized AI agents violating Amazon's terms of use are not permitted.

Meta responded that Muse cannot read users' passwords or payment information. Credentials submitted by users are stored in a secure area; Muse can use them but cannot view the plaintext. The two companies have a business relationship: since 2023, users have been able to buy Amazon products directly on Facebook and Instagram, and Meta signed a multi-billion-dollar agreement in April 2026 to run its AI agent workloads on Amazon's cloud platform.

The dispute highlights a broader industry question about who controls the online shopping experience and customer relationships when AI agents shop on behalf of consumers. Over the past year, Amazon has increasingly blocked external AI agents from scraping its site, including filing a lawsuit against Perplexity's Comet browser and blocking shopping agents from Google and OpenAI. In March 2026, Amazon obtained a preliminary injunction against Perplexity, but the Ninth Circuit Court of Appeals overturned it on August 4, and on September 10 the court denied Amazon's request for rehearing.

Amazon said it has asked Meta to remove amazon.com from Muse's list of available services, emphasizing that third-party agents should operate transparently and respect merchants' decisions. When asked whether it would take legal action, Amazon declined to comment.
