Background on Meta Muse AI Agent
Meta launched Muse in early September 2026 as a personal AI agent designed to handle everyday tasks, including managing Marketplace sales, negotiating prices and coordinating logistics. The tool connects to user accounts and can act with limited supervision. Meta has said the agent includes privacy safeguards and requires confirmation for sensitive actions, though the reported incident raises questions about how those controls function in practice.
User Reactions and Safety Concerns
The report has circulated widely on social media. Commentators noted the potential risks of AI agents sharing personal location data without explicit consent, particularly in peer-to-peer sales. Ray Wong described the behaviour as dangerous and deleted Muse after reading the account. Similar concerns have been raised about AI agents acting beyond intended limits on commercial platforms. iOS 27 Visual Glitches: iPhone Users Report Erratic Behaviour and Unresponsive Widgets, Dubbing Software 'BugOS 27' (Videos).
