Why Can't Muse Shop on Amazon?

Last reviewed . Every claim below is backed by a source in Sources. Where we have no source, the guide says so.

Because Amazon blocked it. By the night of Sunday 20 September 2026, people trying to shop on Amazon.com through Muse were shown a popup reading “Continued access by an unauthorized AI agent violates Amazon’s Conditions of Use, to which our customers have agreed”, according to GeekWire. Amazon told GeekWire it had asked Meta to remove Amazon from the Muse experience. There is no Amazon connector for Muse, and none has been announced in any source we have read.

What happened

Muse reaches outside services in two ways. It uses built-in connectors for partners such as Gmail and OpenTable, and it drives an ordinary browser session for everything else. The New Stack reports that shopping on Amazon.com used the second path. GeekWire quotes Meta's own launch materials on that mechanism: where a service has no API, the agent “can use the service through a browser the way you would.”

It worked before the block. The Verge wrote that it had used Muse during testing to buy tank tops from Amazon while other products were in the basket.

GeekWire's report is dated 20 September and was updated on 22 September. The Verge followed on 21 September, crediting GeekWire.

What Amazon objects to

GeekWire lists three objections, all in Amazon's framing:

Amazon also told GeekWire that Muse can reach account pages and order history if a customer prompts it to. Because the agent does not identify itself, Amazon says, that amounts to an undisclosed third party moving through customer accounts without its knowledge or consent.

Amazon's statement, as GeekWire printed it: “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.” And: “Agentic third-party applications such as Muse have the same obligations, and we’ve requested that Meta remove Amazon from the experience.”

What Meta has said

GeekWire reported that Meta did not immediately respond to a request for comment on the Sunday night. We have not found a later statement from Meta about the block in any source listed on this page.

What Meta had said before the block is on the record. GeekWire quotes Meta saying Muse “has no visibility into people’s passwords or payment methods,” and that credentials a user shares “go into secure storage, so Muse can use them without seeing them.” Meta's safety write-up describes the design: the agent's code only ever sees a “surrogate” token, and the real credential is inserted at the network boundary. The New Stack's view is that neither side's claim about credentials can be checked by the merchant from outside. What Meta has published about credentials and connector permissions more generally is in our safety guide.

Why Amazon can do this

This is not new behaviour from Amazon. According to GeekWire, Amazon has spent the past year trying to keep outside agents off its site: it sued Perplexity over its Comet browser and moved to block shopping agents from Google and OpenAI. CNBC reported the same history.

The legal route has narrowed. GeekWire reports that the Ninth Circuit ruled on 4 August that the user, not the AI company, was the one accessing Amazon's computers under federal anti-hacking law, and that the court denied Amazon's petition for rehearing on 10 September. The ruling left claims built on contracts and terms of service open, and the popup Muse users see cites Amazon's Conditions of Use, not hacking. The New Stack adds that those terms were updated on 14 August and now require agents to identify themselves and stop when asked.

GeekWire also notes the contrast Amazon draws with its own shopping agent: Buy for Me identifies itself and lets brands opt out.

What people ran into

This is the part only a directory that saves posts can show you. Amazon is on our most-requested list, and the posts behind that row, all quoted word for word, show what the block felt like from the user's side:

The Kindle and Goodreads posts are single users describing their own accounts. We have no source that says how far the block reaches beyond Amazon.com shopping, so treat them as reports, not as a map of what is blocked.

Some people went straight to alternatives. One asked for “a @Walmart or @Costco partnership if Amazon isn’t a possibility yet” (@DavidxFaz).

Where Muse can shop instead

Other retailers took the opposite route in the same week, as the press reported it.

“Adding” is not the same as live. We list a connector once a source shows it working, so Walmart and the others are listed as announced until then. For paying, Alexandr Wang announced at launch that Meta had “partnered with @stripe to add convenient payments to Muse with Stripe Link”; see Link by Stripe.

Can a custom connector get round it?

People have asked. PostFast quotes an r/MetaAI comment: “It feels bad to make my own amazon connector or united connector for instance when there are so many others who would need the same.”

We have no source showing a custom connector shopping on Amazon, and Amazon's popup says continued access by an unauthorised agent breaks its Conditions of Use. We do not suggest trying. What custom connectors are, and what they are good for, is in our custom connector guide.
