Example Prompts
Once connected, you can ask your AI assistant things like:
- "Dim all my monitors to 30%"
- "What displays are connected?"
- "Switch my Dell monitor to HDMI"
- "Activate my Night Mode preset"
- "Sync all displays to my main monitor"
- "Turn up the brightness on my external display"
- "Set up my coding environment — brightness 70, contrast 60"
How It Works
The MCP server wraps the displaybuddy CLI, which communicates with the running DisplayBuddy app via URL scheme. All operations are local — no data leaves your machine.
AI Agent → MCP Server → displaybuddy CLI → DisplayBuddy App → Your Monitors
