Desktop automation MCP for AI agents — screenshot, mouse, keyboard, window inspection. Lets any MCP-capable agent (Claude, Gemini, Codex, Copilot, Vibe) see and interact with the KpihX-Ubuntu desktop.

The Problem

AI agents are blind to the desktop by default. They can read files and call APIs, but they cannot see what is on screen, click buttons, type in forms, or react to GUI state. desk-mcp bridges that gap — it exposes the desktop as a set of simple MCP tools that any agent can call over the standard stdio transport.

Architecture

desk-mcp serve  (FastMCP, stdio transport)
│
├── screenshot()      XDG Desktop Portal  →  /usr/bin/python3 + dbus + GLib
│                     Full screen  →  optional crop (window name or {x,y,w,h})
│
├── get_windows()     xdotool search + getwindowgeometry
├── get_screen()      xdotool getdisplaygeometry + env vars
│
├── click()           xdotool mousemove + click
├── double_click()    xdotool click --repeat 2
├── right_click()     xdotool click 3
├── move_mouse()      xdotool mousemove
├── type_text()       xdotool type --delay <ms>
├── key()             xdotool key --clearmodifiers <combo>
└── scroll()          xdotool click (button 4/5/6/7)

Screenshot backend: XDG Desktop Portal via dbus-python + GLib. Works natively on GNOME Wayland without any dialog or user interaction. Does NOT depend on gnome-screenshot or grim.

Input backend: xdotool via XWayland. Covers all X11 and XWayland apps. For pure Wayland-native apps (e.g. WaveTerm in native mode), mouse coordinates are correct but window auto-detection via get_windows() may not see them.

Install

Prerequisites

sudo apt install xdotool python3-gi python3-dbus

From PyPI

uv tool install desk-mcp

Editable (development)

git clone [email protected]:KpihX/desk-mcp.git ~/Work/AI/MCPs/desk_mcp
cd ~/Work/AI/MCPs/desk_mcp
uv tool install --editable .

Usage

Claude Code (~/.claude.json)

"desk-mcp": {
  "command": "/home/kpihx/.local/bin/desk-mcp",
  "args": ["serve"],
  "env": {
    "DISPLAY": ":0",
    "DBUS_SESSION_BUS_ADDRESS": "unix:path=/run/user/1000/bus",
    "XDG_RUNTIME_DIR": "/run/user/1000",
    "WAYLAND_DISPLAY": "wayland-0"
  }
}

Note: The display env vars must be injected explicitly because Claude Code does not inherit the user's graphical session environment.

Gemini (~/.gemini/extensions/desk-mcp/gemini-extension.json)

{
  "name": "desk-mcp",
  "version": "0.2.0",
  "description": "Desktop automation MCP for Gemini — screenshot, mouse, keyboard via xdotool.",
  "mcpServers": {
    "desk-mcp": {
      "command": "/home/kpihx/.local/bin/desk-mcp",
      "args": ["serve"],
      "env": {}
    }
  }
}

CLI test

desk-mcp status        # check environment and tool availability
desk-mcp screenshot    # take a test screenshot and print the path
desk-mcp serve         # start the MCP server (stdio)
