Amazon has blocked Meta’s Muse AI agent from shopping on Amazon.com after asking Meta to remove the retailer from Muse’s shopping experience. Users began encountering the restriction on Sunday, Sept. 20.
Muse relies on browser access when a direct integration is unavailable, leaving those workflows subject to the destination platform’s rules and technical controls. Agent-driven purchasing or procurement can therefore stop working when a third-party platform withdraws access.
Users attempting to shop on Amazon through Muse are now shown a warning that access by an unauthorized AI agent violates Amazon’s Conditions of Use. Amazon said Meta had not notified the company that Muse would access its store and that Amazon had not authorized the integration, according to reporting from The Verge.
Meta launched Muse in the US on Sept. 8 as a personal AI agent designed to browse websites, fill out forms, book travel, and make purchases. Muse runs through a cloud-based virtual machine with its own browser and can continue working after a user closes the app.
Amazon challenges Muse’s access method
Amazon says Muse does not identify itself as an AI agent while browsing Amazon and can access customer account information when acting on a user’s instructions. The company also raised concerns about how credentials are handled and said third-party purchasing agents should operate transparently and respect platform rules, GeekWire reported.
Meta has not publicly responded directly to Amazon’s allegations. Its existing Muse security documentation says the agent cannot see users’ passwords or payment methods because credentials are kept in secure storage that Muse can use without viewing them.
Meta also says a separate Sentinel agent reviews Muse’s actions before they reach the internet and that users must approve sensitive actions such as purchases. Stripe’s Link can generate a one-time card so merchants do not receive the user’s actual card number.
Muse can use a browser when a direct integration is unavailable. Such workflows remain subject to a destination platform’s access controls as companies develop browsers specifically for AI agents.
Amazon fought Perplexity over similar access
Amazon has already fought another AI company over automated shopping access. It sued Perplexity over the Comet browser’s AI assistant and initially obtained a preliminary injunction restricting the agent’s use on Amazon.
The US Court of Appeals for the Ninth Circuit vacated that injunction on Aug. 4. The court found Amazon was unlikely, at that stage, to prove Perplexity itself “accessed” Amazon’s computers under federal and California anti-hacking laws because the user, rather than Perplexity, was accessing Amazon with help from the agent. The ruling did not prevent Amazon from regulating access through private terms of service.
Other commerce platforms are choosing to support AI agents. Shopify has added Meta as an AI commerce channel and is expanding its partnership to support Muse transactions through Shop Pay, while its documentation describes direct checkout through Meta. The shift is raising questions about who controls customer relationships in AI shopping as assistants increasingly sit between shoppers and retailers.
Browser-based agent workflows need fallback options when they handle critical purchasing or procurement tasks because access can disappear without changes to the agent itself.
