Displaybuddy Mcp

biocross/displaybuddy-mcp

Wraps the DisplayBuddy CLI to give Claude control over your Mac's external monitors without leaving the keyboard. Exposes tools for adjusting brightness, contrast, volume, and input source across connected displays, plus activating saved presets and toggling automation schedules. You can sync settings across multiple monitors or target specific displays by UUID. Everything runs locally through DisplayBuddy's URL scheme, so you need the app installed and its CLI tool set up first. Useful when you're already chatting with Claude about your workflow and want to adjust your display setup without breaking focus to hunt for hardware buttons or menu bar controls.
