How a cloud AI agent joined a home network via Tailscale and drove a radio

Security researcher David Maynor explains how Muse, a cloud-hosted AI agent service he uses but doesn't own, securely reached machines behind his home NAT using built-in Tailscale and MCP with narrow, revocable permissions—and drove radio hardware.
Previously the router was a wall: he'd paste agent commands into terminals and paste outputs back, 'becoming the USB cable.' Muse shipping with Tailscale quietly removes that wall. He argues the design matters: letting a service you use (not own) reach into your network only makes sense when access is narrow, user-approved, and revocable.
