Amazon Locked Meta's Muse Agent Out of Its Store

Amazon's patience with outside AI agents just ran out again, and this time the target was a partner it works with elsewhere. The retail giant cut off Meta's new Muse agent from Amazon.com on Sunday night, twelve days after launch, after Meta declined Amazon's request to voluntarily remove the site from Muse's shopping capabilities.

Shoppers trying to buy through Muse now hit a blunt pop-up: "Continued access by an unauthorized AI agent violates Amazon's Conditions of Use, to which our customers have agreed." Amazon laid out its objections in a statement, and they go well beyond simple gatekeeping. A few specifics stand out from the dispute:

• Amazon says Muse doesn't identify itself when browsing, and appears to capture and store customer credentials while scraping account data
• An Amazon spokesperson compared the arrangement to food delivery apps working with restaurants, arguing agentic tools "should operate openly and respect service provider decisions about whether or not to participate"
• The block follows a pattern: Amazon has already sued Perplexity over its Comet browser and separately restricted shopping agents from Google and OpenAI

What makes this standoff notable is that Amazon and Meta aren't strangers — Meta signed a multibillion-dollar deal in April to run agentic AI workloads on Amazon's Graviton chips, and Amazon products have been purchasable inside Facebook and Instagram since 2023.

That existing relationship didn't stop the block. As TechCrunch's analysis notes, Amazon has its own foundation models and one of the internet's most popular inference platforms, giving it every incentive to keep outside agents — and the customer relationship they'd otherwise capture — off its own turf.

Muse still works across the rest of the web through Stripe's Link checkout, but the largest online store in the US just made clear it intends to set the terms on its own shelves.
