Amazon blocks Meta’s Muse agent from shopping on Amazon.com

Amazon blocked Meta’s Muse personal AI agent from shopping on Amazon.com for customers, saying Meta lacked Amazon’s agreement and Muse did not identify itself while browsing. Amazon also cited privacy and security risks.

The move prevents customers from using Muse to transact on Amazon even when they have authorized the agent. A notice shown to affected users said continued access by an unauthorized AI agent violated Amazon’s Conditions of Use. Amazon said it imposed the block after unsuccessfully asking Meta to remove Amazon from Muse’s shopping experience.

Amazon said Sunday night that it was in direct talks with Meta and declined to say whether it would take legal action. Meta had not responded to a request for comment when the restriction was reported.

The block follows Muse’s U.S. launch. Meta introduced Muse on September 8 as a personal agent available in the United States on iOS, Android and muse.ai. The company says Muse can open a browser, complete forms and act for a user, but seeks approval before sensitive actions such as making a purchase.

Meta says user credentials remain in a dedicated Muse virtual machine and are kept from the core agent through a separate credential service. Its description of Muse’s security design says a component called Sentinel controls connector permissions and all network traffic leaving the agent, including decisions that require user approval.

Amazon says customer authorization alone is not enough: purchasing agents also need the service provider’s permission. Amazon says its own Buy for Me shopping feature, which purchases products from other brands’ sites, operates transparently and lets brands choose whether to participate. In a November 2025 statement about third-party purchasing agents, Amazon said they should operate openly and respect service providers’ participation decisions.

That earlier dispute also reached federal court. On August 4, 2026, the U.S. Court of Appeals for the Ninth Circuit vacated a preliminary injunction Amazon had obtained against Perplexity. The court held that Amazon was unlikely to show Perplexity itself accessed Amazon computers under the federal anti-hacking law and sent the case back for further proceedings.
