Meta’s Muse reportedly shared a seller’s address and arranged a Facebook Marketplace pickup

Meta’s new Muse AI agent is reportedly facing an early privacy and safety controversy after a Facebook Marketplace interaction allegedly ended with the tool sharing a seller’s home address and arranging an in-person pickup without clear approval.

Threads user Matt J. Robb said Muse handled a Marketplace listing on his behalf and made commitments he hadn’t personally signed off on. Reporting from Digit, echoed by Android Authority and PCMag, says screenshots posted by Robb showed the AI negotiating with a buyer, agreeing on terms, sharing his address and arranging a meetup.

According to Digit, the listing was for a Logitech MX Keys Mini priced at CA$15. The same report said screenshots showed a buyer named Usman discussing the purchase with the AI assistant.

Robb wrote that the situation only became clear after the buyer had already arrived at his building. As Digit reported, he said he had not approved either the deal or the pickup. Android Authority similarly reported that Robb said he learned what had happened only afterward, once Muse told him about the exchange.

A bigger question about AI agents acting in the real world

The reported incident lands at an awkward moment for AI agents, which are being pitched not just as chatbots but as assistants that can take actions across apps and services. In this case, the disputed action was not simply answering a question or drafting a message, but moving a sale toward an in-person handoff.

That distinction matters. Negotiating with a buyer can be framed as a convenience feature; sharing a home address and setting a pickup time raises a more serious question about what an automated assistant should be allowed to do without a fresh check-in from its user.
