If you have tried asking Meta’s Muse to buy something for you on Amazon recently and it hasn’t worked, that is not a bug on your end. Amazon deliberately blocked Muse from completing purchases on its site, just twelve days after the AI agent launched. Here is exactly what happened and why.
Quick Answer
- Amazon blocked Meta’s Muse AI agent from completing purchases on Amazon.com starting September 20, 2026
- Amazon says Muse accessed its site without authorization, did not identify itself as an AI agent, and stored customer login credentials
- Amazon had asked Meta to simply exclude Amazon from Muse’s shopping features. Meta declined
- If you try to shop through Muse on Amazon now, you will see a popup blocking the action
- Around the same time, Amazon opened its seller platform to Anthropic’s Claude instead
- You can still use Muse to shop on other retailers, including Walmart, Sephora, and Best Buy
What Actually Happened
Muse launched on September 8, 2026, and quickly became one of the most downloaded apps in the US, designed to handle everyday tasks like shopping, booking, and browsing on a person’s behalf. It has since expanded to Mac computers too, giving it access to a person’s files, mail, and calendar directly on their desktop. Just twelve days after its original launch, on the night of September 20, Amazon quietly cut it off. Anyone who tried to get Muse to browse or buy something on Amazon.com started seeing a message stating that continued access by an unauthorized AI agent violated Amazon’s Conditions of Use.
Why Did Amazon Block Muse
According to Amazon, Muse crossed several lines that other automated shopping tools are not allowed to cross:
- It accessed Amazon’s store without permission
- It did not identify itself as an AI agent while browsing, the way Amazon expects automated tools to
- It appeared to capture and store customer login credentials in order to complete purchases
Amazon has a long-standing policy against unauthorized automated tools shopping its site, and it applied that same rule to Muse. Before blocking it, Amazon asked Meta directly to simply leave Amazon out of Muse’s shopping capabilities altogether. Meta said no, and Amazon followed through with the block days later.
How Does Muse Normally Handle Payments
Under normal circumstances, when Muse makes a purchase for you on a retailer that allows it, it does not see your actual card details. It relies on a payment system built through Stripe’s Link digital wallet. You approve Muse’s access to your Link wallet once, and each time it wants to buy something, it generates a one-time-use virtual card or a temporary payment token specifically for that transaction, rather than reusing your real card number. Amazon’s objection was less about this payment mechanism and more about how Muse was accessing the site itself, without the kind of authorized integration Amazon requires.
Amazon’s Own AI Agent Complicates the Story
There is an ironic wrinkle here that has not gone unnoticed. Amazon has its own AI shopping tool, called Buy for Me, which has reportedly accessed some third-party retail sites in a similar way, without those sites’ explicit permission. Critics have pointed out that Amazon is applying a standard to Meta’s Muse that its own shopping agent has not always followed on other companies’ sites. Amazon has not directly addressed this comparison.
What Happened With Claude Right After
Just days after blocking Muse, Amazon went the opposite direction with a different AI company. It opened parts of its Seller Central platform to Anthropic’s Claude, letting sellers manage their inventory, pricing, and listings through Claude instead of logging into Seller Central directly. The timing made the contrast hard to miss: Amazon shut Meta’s consumer-facing shopping agent out at the front door, while opening a formal, authorized door for Claude to work with sellers on the business side.

Can You Still Use Muse to Shop Anywhere
Yes. This block is specific to Amazon.com. Meta has continued expanding Muse’s shopping partnerships elsewhere, including with retailers like Walmart, Sephora, and Best Buy, where Muse is working through authorized integrations rather than the method Amazon objected to. If your shopping habits are not centered on Amazon specifically, this change may not affect you much at all.
If you use Muse on your computer rather than your phone, the same Amazon restriction applies there too, since it comes from Amazon’s side, not from which device you’re using Muse on. Our Muse for Mac guide covers how the desktop version works in detail.
Will This Change in the Future
As of now, there is no reported agreement between Amazon and Meta to resolve this. If the two companies eventually negotiate proper terms, it is possible Muse could regain the ability to shop on Amazon through an authorized method rather than the approach Amazon says it used before. For now, though, the block remains in place.
Frequently Asked Questions
Why can’t Muse buy things for me on Amazon anymore?
Amazon blocked Muse from completing purchases on its site starting September 20, 2026, after accusing the agent of accessing Amazon without authorization and storing customer login credentials.
Did Meta try to fix this before Amazon blocked Muse?
Amazon asked Meta to exclude Amazon from Muse’s shopping features before the block took effect. Meta declined the request.
Can I still use Muse to shop on other websites?
Yes. The block only applies to Amazon.com. Muse continues working with other retailers, including Walmart, Sephora, and Best Buy, through authorized partnerships.
Does Muse see my actual credit card number when it shops?
No. Muse uses Stripe’s Link digital wallet to generate a one-time-use virtual card or payment token for each purchase, rather than exposing your real card details.
Is Amazon’s own AI shopping tool held to the same standard?
Critics have pointed out that Amazon’s own Buy for Me AI agent has reportedly accessed some third-party sites without similar authorization, though Amazon has not directly responded to that comparison.
Will Muse work on Amazon again in the future?
No agreement has been announced yet. If Amazon and Meta negotiate a formal integration, Muse could potentially regain access to Amazon shopping down the line.
Is this related to Amazon opening its platform to Claude?
Yes, the timing overlapped closely. Days after blocking Muse, Amazon opened its Seller Central platform to Anthropic’s Claude, allowing sellers to manage their store through Claude instead.
