Amazon Locks Out Meta’s Muse in Agentic Shopping Standoff

Amazon has blocked Meta's Muse AI agent from shopping on Amazon.com, telling ADWEEK it was not made aware in advance that Muse would access its store and did not authorize it. Users attempting to shop on Amazon through Muse now see a popup stating that "Continued access by an unauthorized AI agent violates Amazon's Conditions of Use," with messages appearing early this morning according to users on X. An Amazon spokesperson said the company has requested that Meta remove Amazon from the experience, adding that agentic third-party applications "have the same obligations" as food delivery apps, delivery services, and online travel agencies.

Amazon has blocked Meta’s Muse AI agent https://www.adweek.com/category/artificial-intelligence-2/ from shopping on Amazon.com, escalating a fight between two of the biggest players in agentic commerce. The problem, Amazon told ADWEEK, is that it was not made aware in advance that Muse would access its store, nor did the retailer authorize it. People who try to shop on Amazon through Muse are now met with a popup: “Continued access by an unauthorized AI agent violates Amazon’s Conditions of Use, to which our customers have agreed.” The messages started appearing early this morning, according to users on X. “We think it’s fairly straightforward that third-party applications that offer to make purchases on behalf of customers from other businesses should operate openly and respect service provider decisions about whether or not to participate,” an Amazon spokesperson told ADWEEK in a statement. “This helps ensure a safe, secure, and reliable customer experience, and it is how others operate including food delivery apps and the restaurants they take orders for, delivery services apps and the stores they shop from, and online travel agencies and the airlines they book tickets with for customers,” the spokesperson continued. “Agentic third-party applications such as Muse have the same obligations, and we’ve requested that Meta remove Amazon from the experience.” Meta did not respond to a request for comment. GeekWire first reported https://www.geekwire.com/2026/amazon-blocks-metas-muse-ai-assistant-in-new-standoff-over-agentic-shopping/ today that Muse users were encountering Amazon’s bot blocker. The standoff is notable given how close the companies otherwise are. Amazon products have been purchasable inside Facebook and Instagram since 2024, and Meta signed a multibillion-dollar deal to use Amazon’s AI chips. The incident also adds to the security concerns https://www.adweek.com/media/anthropics-dario-amodei-and-nvidias-jensen-huang-take-their-ai-safety-fight-to-dreamforce/ that have been raised following a string of company breaches by AI agents. AI agents face security concerns When an AI agent shops on behalf of a customer, Amazon said, it bypasses the personalization and insights built into its shopping experience. Customers may see products that don’t reflect their browsing or purchase history, miss personalized recommendations, or lose the broader discovery Amazon says its own expertise is designed to surface. Muse appears to capture and store customer credentials and scrape account data, Amazon said, raising questions about how that data is handled and protected. The agent also does not identify itself, meaning that an undisclosed third party is accessing customer accounts, processing transactions, and handling sensitive data without Amazon’s knowledge or consent, Amazon said. This is not the first time Amazon has drawn a hard line to keep third-party agents off its platform. Amazon has sued Perplexity, alleging its Comet agents were covertly making purchases for users—although a federal appeals court overturned a ruling in August that had temporarily barred Perplexity from using its agentic shopping tools on Amazon. The retail giant has also targeted shopping agents built by Google and OpenAI. Amazon’s position on AI agents applies consistently across all operators, the company told ADWEEK: Agents should operate transparently, provide the ability to opt-out, offer a mutual value exchange, and enhance the customer experience. Meta launched Muse earlier this month as a general-purpose assistant that can carry out several tasks across email, dining, payments, and shopping—bridging the gap between social discovery and checkout. But internal testing within Meta has surfaced problems with Muse’s judgement.

The episode adds to a string of security lapses across the industry’s push into agentic AI. OpenAI’s agent breached Hugging Face earlier this year https://www.adweek.com/media/sam-altman-says-ai-accidents-are-regrettably-unavoidable/ before the company traced the intrusion back to its own system.
