MCP Support on Windows 11

Let your AI assistant control the screen dimmer for you

MCP (Model Context Protocol) is the open standard that lets AI assistants talk to local apps and tools. Turn Off the Lights for Desktop now ships a local MCP server on Windows 11, so your AI assistant can dim your screen, turn the lights off and on, and tune the dark layer, all from a plain-language request.

How it works

The desktop app runs a local MCP server on your Windows 11 PC. Any MCP-compatible AI assistant you connect to it can call the app's tools directly: no cloud relay, no extra account. Ask your assistant to dim the screen, and the command goes straight from the assistant to the lamp on your taskbar.

What your assistant can control

Through MCP, an assistant can switch the dark layer on and off, and adjust the dimmer settings such as the opacity level. A request like "dim my screen to 80%" or "turn the lights on" becomes an action in the app, so you never have to reach for the lamp button yourself.

Private by design

The MCP server lives on your own machine. Your assistant talks to the app over the local protocol, so nothing about your screen, your apps, or your settings leaves your PC.

How to use MCP on Windows 11

  1. Install Turn Off the Lights for Desktop on your Windows 11 PC from the Microsoft Store.
  2. Open the app settings and follow the built-in MCP installation instructions to enable the local MCP server.
  3. Add the server to your MCP-compatible AI assistant, then ask it to dim your screen, set the opacity, or turn the lights off and on.
