Amazon has blocked Meta’s AI agent Muse from shopping on its store. The move came 12 days after Muse launched. Amazon says the agent “browses without prior notice, does not identify itself, and appears to store customers’ login credentials.” Meta countered that Muse cannot access passwords or payment methods.
Amazon shuts the door on an AI tasked with shopping
Muse is Meta’s AI assistant, designed to take care of digital errands ranging from replying to messages to shopping. It had become so popular that it topped the U.S. App Store charts. Twelve days after its launch, Amazon shut the agent out of its store.
When users try to shop on Amazon through Muse, a pop-up reportedly appears saying that continued access by an unauthorized AI agent violates Amazon’s terms of use.
Let’s lay out the two companies’ positions separately. Amazon says Meta did not notify it that Muse would access its store, that the agent does not identify itself while browsing, and that it appears to obtain and store customers’ credentials. Meta, by contrast, says Muse cannot see users’ passwords or payment methods; shared credentials are kept in a secure storage area, and the agent uses them without seeing their contents.
In other words, what we can confirm is only that “the agent was blocked and the companies’ accounts conflict.” We can only weigh the two companies’ claims side by side; the actual handling of credentials remains unclear.
It’s not just about passwords
The stated issues are security and identification. But there appears to be a larger tug-of-war in the background. If AI handles everything from choosing products to checkout, users will spend less time looking at search results and ad placements.
Amazon’s advertising business is supported by sponsored listings in search results and is estimated to be worth $56 billion. AI agents could bypass a system that depends on getting products in front of human eyes.
Over the past year, Amazon has strengthened its defenses against outside agents. After a lawsuit over Perplexity’s Comet browser and blocks on shopping agents from Google and OpenAI, Meta is now the latest company to be named.
Startups have weighed in, too. OpenClaw developer Peter Steinberger has said, in effect, that a “digital knife fight” most people are overlooking is about to begin. Who gets to open the store’s door, and who controls the path to the checkout? The password issue may be just the beginning.
Muse expands to devices and partners
Meta, meanwhile, shows no sign of slowing Muse’s momentum. At Connect 2026, it unveiled Charm, a keychain-style device. CEO Mark Zuckerberg described it as the fastest way to talk to Muse, and it is expected to launch in December.
Muse is also set to arrive on AI glasses within the next few months. The system is designed to act based on what users see, and Meta says it will offer a private processing mode that excludes Meta data as well. The company also previewed real-time voice and video conversations and Muse Realtime Avatar, an avatar feature that moves in sync with speech. Meta says evaluators preferred its avatar to those from Runway and HeyGen.
The list of partners is growing, too. PayPal, Walmart, Shopify, GitHub, and Box were named in an announcement made the same week Amazon’s block was reported. Meta has also released connectors that let developers link external apps to Muse.
While one store door has closed, companies in payments, retail, and development infrastructure have been gathering around Muse. The conflict with Amazon should be viewed in the context of Muse expanding its reach.
User choice comes into question behind the convenience
From here on, this is my opinion. The more AI handles the purchasing process, the harder it becomes for users to know which stores they saw, what they were recommended, and where they bought something. In exchange for convenience, the process of making choices becomes a black box.
Stores have their own arguments, too. If they cannot tell who is visiting, it becomes harder to prevent fraud, measure advertising effectiveness, and serve customers. Requiring AI agents to identify themselves and make clear that they are acting on a user’s behalf may become a minimum rule.
The technical method Amazon used to block Muse and the details of how Meta stores credentials have not been disclosed. Even so, the question of who controls the gateway to shopping—the platform or the agent chosen by the user—has already come to the fore.
The next time I ask an agent to shop for me, I’ll want to pause and consider whose interests shaped the results and the stores they show.
