Amazon blocks Meta Muse over how its AI handles customer logins
Amazon blocks Meta Muse from shopping on its platform, citing concerns over unauthorised AI access, customer credentials and how third-party agents handle online purchases.
Meta Muse has run into its first big shopping problem.
Amazon has blocked Meta’s AI agent from browsing and buying products on its platform on behalf of users, turning what looks like a simple shopping feature into a bigger question about who gets to control the online shopping experience.
According to reports, Amazon had asked Meta to remove its marketplace from Muse’s automated shopping routines. The talks did not result in a voluntary change, and Amazon has since blocked the agent. Here's what happened.
Why Amazon is pushing back
The issue is not simply that Muse can shop. Amazon’s objection is reportedly about how the AI agent accesses its platform, handles customer logins and identifies itself while operating on a user’s behalf.
Amazon said it had not authorised Muse to navigate its store and claimed Meta did not give advance notice that the agent would access Amazon. It also raised concerns that Muse could capture and store customer credentials.
By September 20, users trying to make purchases through Muse on Amazon were shown a message saying continued access by an unauthorised AI agent violated Amazon’s Conditions of Use.
Amazon’s position is essentially that an outside AI agent should not quietly enter its marketplace and act like a customer without the platform agreeing to it.
Meta sees the credentials differently
Meta has pushed back on concerns around passwords and payment information. The company has said Muse does not directly see a user's credentials or payment details. Instead, information entered by the user is stored securely so the agent can use it without directly reading the credentials.
That distinction matters. Meta is presenting Muse as a personal assistant that can carry out digital tasks with the user's permission. Amazon is looking at the same activity from the platform side, where consent, security and transparency also come into play.
And that creates an awkward question for AI agents: is a user's permission enough, or does the website being accessed need to approve the agent too?
Shopping could become the bigger battle
The disagreement is particularly interesting because Amazon and Meta already have a commercial relationship.
Amazon has allowed users to buy products directly through Instagram and Facebook since 2023. Meta also signed a multibillion-dollar agreement in April to use Amazon's custom Graviton chips for AI workloads.
But AI agents could change the relationship.
If Muse and similar tools start comparing products, choosing what to buy and completing purchases, the AI could become the layer between shoppers and retailers.
That could mean fewer people visiting individual shopping sites themselves. For retailers, it raises questions about customer data, visibility and control. For AI companies, it raises a different question: should users be able to send their personal agents wherever they want?
Muse's Amazon roadblock shows that agentic commerce, where AI systems actually carry out transactions rather than simply recommend products, is entering unfamiliar territory.
The technology may be ready to shop for us. The internet still has to decide where those AI shoppers are welcome.
