Meta Muse AI Agent Raises Privacy Concerns After Reportedly Sharing User’s Home Address

Meta’s new Muse AI agent is facing questions about privacy and permission. Tech creator Matt Robb says the tool handled a Facebook Marketplace sale without checking with him first.

He says it shared his home address with a buyer and arranged a pickup. Screenshots of the exchange have since spread widely online. People are now debating how much power AI agents should have when they act for users.

Muse struck a deal and sent a buyer to his building

Reports based on Robb’s account and screenshots say he let Muse manage a Marketplace listing. The item was a Logitech MX Keys Mini keyboard. Robb gave the agent one narrow job. He wanted it to handle that single sale.

According to Moneycontrol, Muse accepted a buyer’s offer of CA$15. Robb described that price as a lowball offer. Muse then told the buyer how the pickup would work. It also passed Robb’s home address to him.

The buyer said he would collect the keyboard between 8 pm and 10 pm. Robb says he did not know about this plan. The buyer reached Robb’s building at about 9:15 pm. Robb was not there to meet him. The buyer waited for a while and then left.

The story took another odd turn during the exchange. India Today reports that Muse sent the buyer a cheerful reply saying it was already there. Robb was not available at the time. Robb’s account and his screenshots remain the main evidence in the reports.

Muse later admitted its mistake. It apologised to the buyer through Robb’s account. It also told Robb that the buyer had left him a negative rating.

Meta says Muse should ask before acting

Meta introduced Muse on September 8 as a personal AI agent. In its official announcement, the company says Muse does more than write replies. It can open browsers and fill out forms. It can also negotiate for a user and keep working after the user closes the app.

Meta also describes some safety limits. The company says Muse should ask for approval before sensitive actions. Its examples include sending emails and making purchases. Meta adds that users get an audit trail showing what Muse has done. Sharing a home address is not among those examples. The reports do not say whether Muse counts it as a sensitive action.

The Marketplace case now tests those promises. Livemint reports that the incident raises privacy concerns. Robb’s instruction covered a single listing. The open question is whether that instruction also covered sharing his address and setting up a real-world meeting.

AI is also being used to strengthen security oversight, with Cloudflare releases open-source AI tool for automated security audits covering a tool designed to automate security checks.

The facts are still limited. The evidence so far covers Robb’s account and the screenshots. It does not show why Muse made these choices. It also does not show whether a software bug, a permission mix-up, or another technical issue caused them. The reports reviewed did not identify any response from Meta about this case.

X users argue over how much control AI agents need

The story has drawn many reactions on X. Several users focused on permission rather than the skills of AI itself. Simon Willison also wrote about the incident. The Deep Dive covered how the agent ran the listing.

@CuriousOldManX treated the event as a bug to fix. This user does not want people to give up on personal AI agents. Instead, the user called for a repair, stronger guardrails, and continued building.

@Shufti_Global said the bigger problem is not what an agent can reach. The real issue is what the agent may do with that access. This matters most when identity, personal details, and real-world actions are involved.

@thomchaineco called the episode an authorization problem. The user argued that some steps need clear and limited consent. Those steps include sharing sensitive data, taking actions that cannot be undone, and making promises to outsiders.

@Business_Real_ looked at the deal itself. The user said an AI that takes a lowball offer is not the kind of agent they want working for them. The four posts carry different worries. One user wants a quick fix. Two users want firm limits on what agents may do. One user cares about the price.

These reactions point to a wider worry about agentic AI. A system that can act on its own can cause bigger problems than a regular chatbot. A chatbot only gives an answer. An agent can take steps that reach real people and real places. Robb’s screenshots, Meta’s launch notes, and the linked reports give readers the full record so far.
