Dittu MCP Server

Dittu turns a phone into the eyes and hands of an AI assistant. Stand the phone on a tripod facing a monitor — the camera reads the screen, Bluetooth pairs as a real mouse and keyboard. No software to install on the target computer, no remote-desktop setup.

Why a camera instead of screen-sharing?

Because it works on any computer — no software to install, no permissions to configure, no remote-desktop setup. If the monitor is in front of the phone, an AI assistant can see it and control it.

Built for

• Automating repetitive desktop tasks
• Controlling a computer you can't install anything on
• Letting an AI assistant actually do things on-screen, not just describe them
