Common questions

Is Displaybuddy MCP safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.0) reached the registry 8 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

DisplayBuddy MCP Server

An MCP (Model Context Protocol) server that lets AI agents control Mac monitors via DisplayBuddy — adjust brightness, contrast, volume, input source, apply presets, sync displays, and more.

Works with Claude Desktop, Cursor, Windsurf, Cline, and any MCP-compatible client.

Prerequisites

macOS with DisplayBuddy installed and running
DisplayBuddy CLI installed: open DisplayBuddy > Settings > General > Install CLI Tool
Node.js 18+

Installation

Claude Desktop

Add to your claude_desktop_config.json:

"mcpServers": { "displaybuddy": { "command": "npx", "args": ["-y", "displaybuddy-mcp"] } } }

Cursor

Add to your MCP settings:

"mcpServers": { "displaybuddy": { "command": "npx", "args": ["-y", "displaybuddy-mcp"] } } }

Smithery

npx -y @smithery/cli install displaybuddy-mcp --client claude

Available Tools

Tool	Description
`displaybuddy_status`	Quick overview of all displays (call this first)
`displaybuddy_list`	Full display details including UUID, type, capabilities
`displaybuddy_get`	Get properties of a specific display
`displaybuddy_set`	Set brightness, contrast, volume, input, rotation
`displaybuddy_preset_list`	List saved presets
`displaybuddy_preset_activate`	Activate a preset (with optional delay)
`displaybuddy_schedule_list`	List automation schedules
`displaybuddy_schedule_toggle`	Enable or disable a schedule
`displaybuddy_sync`	Check/enable/disable multi-display sync

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
