Amazon Blocks Meta’s Muse AI Agent From Shopping on Its Platform

Amazon has blocked Meta’s new artificial intelligence agent from shopping on its retail site after the social media company declined a request to remove the bot. Meta’s Muse, which was introduced earlier this month, is designed to help people carry out common online tasks such as shopping and booking appointments .

Amazon prohibits other companies from deploying automated tools to shop its site and began blocking Muse on Sunday night, a spokesperson said. Shoppers using Muse now see a series of pop-ups saying its use violates Amazon’s terms of use .

The Block and Amazon’s Objections

The pop-up message reads: “Continued access by an unauthorized AI agent violates Amazon’s Conditions of Use, to which our customers have agreed” . Amazon says Meta never notified the company that Muse would access its store, and that the agent does not identify itself as an AI when browsing. The retailer also claims Muse “appears to capture and store customer credentials,” raising privacy and security concerns .

Amazon spokesperson Lara Hendrickson stated: “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. Agentic third-party applications such as Muse have the same obligations, and we’ve requested that Meta remove Amazon from the experience” .

Meta’s Defense

Meta disputes Amazon’s characterization of its credential handling. The company states that 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 also says a separate monitoring agent called Sentinel must approve anything Muse sends to the internet, and that users must approve sensitive actions such as purchases .

Meta did not immediately respond to requests for comment from multiple outlets .

Part of a Larger Battle Over Agentic Commerce

The standoff between the two tech giants is notable because the companies are also business partners. Amazon products have been purchasable inside Facebook and Instagram since 2023, and Meta signed a multibillion dollar deal in April to run agentic AI workloads on Amazon’s cloud .

The dispute highlights growing tension between e-commerce companies and AI developers over who controls access to online marketplaces as shopping agents become more capable. 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 .

That legal battle had mixed results. Amazon won a preliminary injunction against Perplexity in March, but lost it on August 4 when the Ninth Circuit ruled that the user, not the AI company, was the one accessing Amazon’s computers under federal anti-hacking law. The court denied Amazon’s petition for rehearing on September 10 . However, that ruling left open claims built on contracts and terms of service, which is the avenue Amazon is now using against Muse .

Business Stakes

The business stakes are high for Amazon. In addition to operating its flagship e-commerce site, Amazon generated more than $68 billion in ad revenue last year, a business that depends on people browsing its pages and seeing sponsored products. If consumers start using AI agents to buy products, the bots could select other e-commerce sites, costing Amazon sales and advertising revenue .

Amazon operates its own AI-powered shopping tools, including Buy for Me, which finds items on external brands’ sites. The company points out that Buy for Me identifies itself and lets brands opt out . Amazon CEO Andy Jassy said earlier this year that the agentic shopping experience left much to be desired, and that the bots often flubbed pricing or other data .

The Broader Implications

The block marks an early “tollgate” moment for agentic commerce, where a major retailer explicitly treats a mainstream AI assistant as an unauthorized intruder and asserts the right to decide which agents can transact on its platform. Amazon’s Conditions of Use were written around bots and data-mining tools, not reasoning agents capable of logging in, browsing, and buying .

The retail landscape is already bifurcating. eBay updated its user agreement in February 2026 to prohibit unauthorized third-party buy-for-me agents, aligning with Amazon’s defensive posture. Meanwhile, Walmart, Target, Best Buy, and other retailers have chosen integration over exclusion, signing on with AI shopping platforms including ChatGPT Shopping and Perplexity . Shopify has added Meta as an AI commerce channel and is expanding its partnership to support Muse transactions through Shop Pay.
