A cross-platform MCP (and MQTT) server for controlling monitor brightness, contrast, power, and input source over DDC/CI.

Quick Install

Automated & IDE Setup

Copy the AI prompt to install this server into Claude Code, Cursor, or another agent β€” or use 1-click editor setup below.

Add to CursorAdd to VS Code
We couldn’t automatically confirm this listing starts correctly

We ran the install command below but it didn't respond within our test window β€” this can mean a slow first-time install rather than a real problem.

npx -y ddc-ci-control-bridge

No response to initialize.

This is an experimental automated check and can have false negatives β€” missing environment variables, a slow cold install, etc. It doesn’t necessarily mean something’s wrong. Last checked 7d ago.

Overview

This server reads and writes VCP codes over DDC/CI to control monitor brightness, contrast, input source, and other display settings, exposing that control as MCP tools for AI/agent integration. It also includes an optional MQTT client with Home Assistant auto-discovery for IoT/automation setups, and ships as an npm package, npx-runnable command, or standalone executable for Windows, Linux, and macOS.

Use cases

β€’Get or set a monitor's brightness or contrast from an AI agent
β€’Read or write an arbitrary VCP code for advanced monitor control
β€’Re-scan connected monitors and their DDC/CI capabilities
β€’Bridge monitor control into a Home Assistant setup via MQTT

Key features

β€’Read/write arbitrary VCP codes over DDC/CI
β€’Dedicated brightness get/set tools
β€’Optional MQTT client with Home Assistant auto-discovery
β€’Cross-platform: Windows, Linux, macOS
β€’Available as npm package, npx command, or standalone executable

Documentation Overview

DDC/CI Control Bridge

DDC/CI Control Bridge

NPM Version MIT licensed GitHub Release

Install MCP Server Install in VS Code

Multi-protocol server for DDC/CI monitor control with MCP and MQTT support.

Features

  • DDC/CI Monitor Control: Read and write VCP codes to control monitor brightness, contrast, input source, and more
  • Model Context Protocol (MCP): Server with resources and tools for AI/agent integration
  • MQTT Client: Connect to any MQTT broker for IoT/automation platforms
    • Home Assistant auto-discovery support
    • Generic MQTT pub/sub for custom integrations
  • Cross-Platform: Works on Windows, Linux, and macOS
  • Dual Distribution: Available as standalone executable or npm package

Quick Start

Installation

Option 1: NPM Package (Global)

Terminal
npm install -g ddc-ci-control-bridge
ddc-ci-bridge

Option 2: NPX (No Install)

Terminal
npx ddc-ci-control-bridge

Option 3: Standalone Executable

Download the binary for your platform from GitHub Releases:

  • Windows: ddc-ci-bridge-win.exe
  • Linux: ddc-ci-bridge-linux
  • macOS: ddc-ci-bridge-macos

⚠️ Note: The executable requires DDC_API_KEY environment variable to be set, or it will exit immediately.

Windows:

cmd
# Set API key (required)
set DDC_API_KEY=your-secret-key

# Run the executable
ddc-ci-bridge-win.exe

# Or set multiple environment variables
set DDC_API_KEY=your-secret-key
set MQTT_ENABLED=true
set MQTT_HOST=192.168.1.100
ddc-ci-bridge-win.exe

Linux/macOS:

bash
# Make executable (first time only)
chmod +x ddc-ci-bridge-linux  # or ddc-ci-bridge-macos

# Run with API key (required)
DDC_API_KEY=your-secret-key ./ddc-ci-bridge-linux

# Or with multiple environment variables
DDC_API_KEY=your-secret-key MQTT_ENABLED=true MQTT_HOST=192.168.1.100 ./ddc-ci-bridge-linux

Using with MCP Clients:

Configure your MCP client to use the executable path:

config.json
{
  "mcpServers": {
    "ddc-ci-bridge": {
      "command": "C:\\path\\to\\ddc-ci-bridge-win.exe",
      "args": [],
      "env": {
        "MQTT_ENABLED": "false"
      }
    }
  }
}

MCP Client Setup

Choose between Local (stdio) or Remote (HTTP) setup depending on your needs:

  • Local Setup: Run MCP server on the same machine as your monitors (recommended for most users)
  • Remote Setup: Run MCP server on a monitor-connected machine, access from other devices

πŸ–₯️ Local Setup (stdio - Same Machine)

Use this if your MCP client is on the same machine as your monitors.
