Overview

From the repository's own README, as read at the audited commit. Badges and raw HTML are left out.

A Model Context Protocol server that provides desktop automation capabilities using RobotJS and screenshot capabilities. This server enables LLMs to control mouse movements, keyboard inputs, and capture screenshots of the desktop environment.

Configuration to use Desktop Automation Server

Here's how to configure Claude Desktop to use the MCP Desktop Automation server:

NPX

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

Permissions

This server requires system-level permissions to:

  • Capture screenshots of your screen
  • Control mouse movement and clicks
  • Simulate keyboard input

When first running Claude Desktop with this server, you may need to grant these permissions in your operating system's security settings.

Limitations

While this server works with various MCP clients, it has been primarily tested with Claude Desktop.

Important: The current implementation has a 1MB response size limit. For screen captures, this means:

  • High-resolution screenshots may exceed this limit and fail
  • Testing has shown 800x600 resolution works reliably
  • Consider reducing screen resolution or capturing specific screen areas if you encounter issues

Requirements

  • Node.js (>=14.x)

What tools does Desktop Automation expose?

6 in total: 5 read-only, 1 that write, and 0 that can delete or overwrite. Every one is listed on this page with its risk.

Is Desktop Automation safe to connect to an agent?

The audit found nothing in the source that contradicts what it says it does, and graded it B (89/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean server reads B.

What credentials does Desktop Automation need?
