In their own words
DDC-CI Control Bridge
DDC-CI Control Bridge is a free project for controlling compatible monitors through DDC/CI. It can manage brightness, contrast, power, and input, and offers command-line or API access. Its Model Context Protocol server provides resources and tools for AI or agent integration, including reading and writing VCP codes, setting brightness from 0 to 100, and rescanning monitors and capabilities. An MQTT client connects it to automation systems. Listed integrations include Home Assistant auto-discovery, openHAB, Node-RED, Domoticz, and generic MQTT platforms. The project is available as an npm package or as standalone executables for Windows, Linux, and macOS. MCP can run locally over stdio or provide remote HTTP/SSE access to other machines on a network. Authentication requires the DDC_API_KEY environment variable. The project is MIT licensed and invites contributions through GitHub issues or pull requests. A monitor must support DDC/CI with the feature enabled in its on-screen settings. On Linux, access may require i2c-dev and membership in the i2c group. Some VCP codes are read-only, and supported codes vary by monitor.
