DDC/CI Control Bridge

defozo/ddc-ci-control-bridge

Gives Claude direct access to your monitor hardware through DDC/CI, exposing brightness, contrast, power state, and input switching as callable tools. Works cross-platform and runs locally via stdio, so there's no network configuration needed. The server also publishes to MQTT if you want Home Assistant integration or other automation hooks. Useful when you're building workflows that need to react to ambient light, enforce break schedules by dimming displays, or coordinate multi-monitor setups. Reads and writes VCP codes directly, so you get low-level control without scripting vendor utilities or hunting for monitor-specific SDKs.
