computer-split-screen-mcp 1.3.0

Model Context Protocol Server via Cross-Platform (Mac & Windows) Split Screen Functions

Computer Split Screen MCP

Cross-platform MCP server that exposes split-screen tools (halves, quadrants, thirds) plus maximize/minimize for both Windows and macOS.
Works with MCP clients via uvx.

Features

• Cross-platform support: Windows and macOS
• Split-screen layouts: Halves, quadrants, thirds, and two-thirds variations
• Window controls: Maximize and minimize
• MCP integration: Full Model Context Protocol server support
• Native performance: Uses PyObjC on macOS and pywin32 on Windows for optimal performance
• No external scripts: Pure Python implementation with native OS APIs

Install / Run via MCP client

Configure your MCP client:

{
  "mcpServers": {
    "computer-split-screen": {
      "command": "uvx",
      "args": ["computer-split-screen-mcp"],
      "env": {}
    }
  }
}

Platform Dependencies

• Windows: Requires pywin32>=306
• macOS: Requires pyobjc-framework-Cocoa>=10.0, pyobjc-framework-Quartz>=10.0, and pyobjc-framework-ApplicationServices>=10.0

What's New in v1.3.0

• Complete macOS rewrite: Replaced AppleScript with native PyObjC implementation
• Improved performance: Faster window operations on macOS using Accessibility APIs
• Better reliability: More robust window detection and positioning
• Enhanced error handling: Graceful fallbacks when platform-specific features are unavailable
• Multi-monitor support: Improved handling of complex display configurations

Technical Details

macOS Implementation

• Uses PyObjC frameworks for native macOS integration
• Leverages Accessibility APIs (AX) for precise window manipulation
• Handles coordinate system conversion between macOS and AX coordinate systems
• Respects macOS-specific features like Dock and menu bar positioning
• Supports both standard windows and document windows

Windows Implementation

• Uses pywin32 for Windows API access
• Implements DPI awareness for high-DPI displays
• Uses DWM (Desktop Window Manager) for accurate frame bounds
• Handles window insets and shadows properly
• Calculates positions as fractions of monitor work area
