Serves as the runtime environment for the MCP server, with Node.js version 14.x or higher required for operation.
MCP Desktop Automation
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
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
