Amazon blocked the shopping agent Muse from Meta from accessing its store
Since 20 September 2026, Amazon has been blocking the shopping agent Muse from Meta from accessing its store — according to Amazon, the agent does not disclose that it is AI and stores data without consent. Amazon previously imposed similar restrictions on agents from Perplexity, Google and OpenAI.
Since Sunday 20 September 2026, Amazon has been blocking the AI shopping agent Muse from Meta from accessing its store. Users see an error message stating that “continued access by an unauthorized AI agent violates the terms of use of Amazon that customers have agreed to". According to GeekWire, Meta deployed the agent on the Amazon platform without a prior agreement. Amazon cited security and privacy concerns: the agent does not identify itself as AI while browsing and appears to store customer data without proper consent, including a risk of capturing login credentials. Meta previously claimed that Muse has no access to passwords or payment details, but The Verge reported that, according to reports so far, the agent can also see the contents of user messages, even though it has not been granted permission to do so.
The Muse agent launched on 8 September 2026 and became the most downloaded free app in the US App Store within a week. During testing, The Verge successfully used it to purchase goods on Amazon.
The block is part of a broader campaign by Amazon against third-party agentic shopping services — the company has already similarly restricted agents from Perplexity, Google and OpenAI. Amazon sued Perplexity in November 2025 over a similar dispute, but the court ruled in favor of Perplexity in August 2026. Meta and Amazon nevertheless remain business partners — according to available information, they signed a billion-scale deal for cloud AI chips in 2025.
Why it matters
The case shows that major e-commerce platforms are willing to actively block third-party AI shopping agents without a formal agreement, across competitors (Perplexity, Google, OpenAI, and now Meta) — for developers of agentic AI services, this means partnership agreements are necessary; otherwise, they risk being put out of operation despite an established business relationship between the companies in another area. For users of such agents, this means a risk of unexpected loss of functionality and uncertainty about what data the agent actually stores.

Two audiences, two different impacts
What this means
For individuals
Users of the Muse app from Meta currently cannot shop on Amazon.com through the agent, and according to Amazon, their data may be stored without proper consent, without this being apparent during use.
For a business
Companies building AI shopping agents risk being blocked and facing legal disputes if they access third-party platforms without an agreement and without transparently identifying the agent; Amazon has already restricted Perplexity, Google, OpenAI and Meta in this way, even though the court ruled against Amazon in the Perplexity case in August 2026.
