Claude's new computer use feature turned my old laptop into a machine I control from my phone

A hands-on experience using Claude's Computer Use feature to manage a Debian-based homelab server remotely from a phone. By letting Claude take screenshots of a Mac, interpret the screen, and act on plain-English instructions, the author was able to check Portainer dashboards, inspect Nextcloud and Cloudflared logs, and diagnose a Docker network isolation issue — all without sitting at a desk. The setup required granting macOS accessibility and screen recording permissions and switching to Chrome, as Terminal was click-only, Safari was read-only, and Brave was undetectable. Despite early limitations, the workflow reduced friction for routine homelab management tasks.
