Documentation Overview
kwin-mcp
Model Context Protocol server for Linux desktop GUI automation on KDE Plasma 6 Wayland
Actively maintained fork of isac322/kwin-mcp. This fork ships the fixes users were waiting for: MCP Python SDK 2.x support, text input in virtual sessions (host keymap isolation), reliable window focus, bounded startup waits, silent input-drop fix, honest error contracts — see the changelog and releases. Install:
uv tool install git+https://github.com/VibeProgramm/kwin-mcp
A Model Context Protocol (MCP) server that enables AI agents (Claude Code, Cursor, and other MCP clients) to launch, interact with, and observe any Wayland application in a fully isolated virtual KWin session -- without affecting the user's desktop. It also supports live desktop automation by connecting to an existing KWin session (real desktop or container) for collaborative workflows. With 30 MCP tools covering mouse, keyboard, touch, clipboard, accessibility tree inspection, screenshot capture, and window management, kwin-mcp provides everything needed for end-to-end GUI testing and desktop automation on Linux.

Why kwin-mcp?
- Isolated sessions -- Each session runs in its own
dbus-run-session+kwin_wayland --virtualsandbox. Your host desktop is never affected. - Live session support -- Connect to a real KDE Plasma desktop or a KWin instance inside a container (e.g.
systemd-nspawn) for collaborative "share my screen" workflows. - No screenshots required for interaction -- The AT-SPI2 accessibility tree gives the AI agent structured widget data (roles, names, coordinates, states, available actions), so it can interact with UI elements without relying solely on vision.
- Zero authorization prompts -- Uses KWin's private EIS (Emulated Input Server) D-Bus interface directly, bypassing the XDG RemoteDesktop portal. No user confirmation dialogs.
- Works with any Wayland app -- Anything that runs on KDE Plasma 6 Wayland works: Qt, GTK, Electron, and more. Input is injected via the standard
libeiprotocol. - Full input coverage -- Mouse, keyboard, multi-touch, and clipboard -- all injected through the isolated session for complete desktop automation.
Use Cases
Automated GUI Testing
Run end-to-end GUI tests for KDE/Qt/GTK applications in headless isolated sessions. kwin-mcp launches each app in its own virtual KWin compositor, interacts via mouse, keyboard, and touch input, then verifies results through screenshots and the accessibility tree -- all without a physical display.
AI-Driven Desktop Automation
Let AI agents like Claude Code autonomously operate desktop applications. The agent reads the accessibility tree to understand the UI, performs actions through 30 MCP tools, and observes the results via screenshots -- creating a complete feedback loop for any Wayland application.
Live Desktop Collaboration
Connect to your real desktop session and let Claude observe and interact with what you see. Use session_connect or pass --default-live-session to make live mode the default. Also supports attaching to KWin running inside containers (e.g. systemd-nspawn) for isolated agent desktops.
Headless GUI Testing in CI/CD
Integrate Linux desktop GUI testing into CI/CD pipelines. kwin-mcp's virtual sessions require no X11 or physical display server, making it suitable for headless environments like GitHub Actions or GitLab CI runners on Linux.
Kiosk and Embedded Device Automation
Automate kiosk interfaces and embedded Linux desktops running KDE Plasma or a bare KWin Wayland compositor. Use session_start for isolated virtual testing of kiosk UIs, or session_connect to attach directly to a live kiosk or embedded device session for real-time automation and diagnostics.
Quick Start
Requires KDE Plasma 6 on Wayland. See System Requirements for details.
1. Install
2. Configure Claude Code
Add to your project's .mcp.json:
3. Use it
Ask Claude Code to launch and interact with any GUI application:
Claude Code will autonomously start an isolated session, launch the app, read the accessibility tree to find buttons, click them, and take a screenshot to verify the result.
Configuration
Recommended: install as a plugin
The fastest way to wire kwin-mcp into your editor is to install one of the bundled plugins. Each plugin auto-registers the MCP server and ships the kwin-desktop-automation skill, which teaches the agent which tool to call when (session-mode selection, the observe → act → verify loop, US-QWERTY vs Unicode typing, AT-SPI2 coordinate translation, and other platform pitfalls).
Claude Code — install the plugin from the marketplace:
OpenCode — add the npm plugin to your opencode.json:
For the full integration guide (manual fallback, customising the skill, troubleshooting), see docs/ai-agent-integration.md.

Running Directly
Available Tools
Session Management (3 tools)
| Tool | Parameters | Description |
|---|---|---|
session_start | app_command? str, screen_width? int (1920), screen_height? int (1080), enable_clipboard? bool (false), keep_screenshots? bool (false), isolate_home? bool (false), keep_home? bool (false), env? dict | Start an isolated KWin Wayland session, optionally launching an app. Set enable_clipboard=true to enable clipboard tools (requires wl-clipboard). Set keep_screenshots=true to preserve screenshot files after session_stop. Set isolate_home=true to create a temporary HOME with isolated XDG directories (config, data, cache, state), preventing apps from reading/writing host user settings. Set keep_home=true to preserve the isolated home directory after session_stop. Pass extra environment variables via env. |
session_connect | dbus_address? str, wayland_display? str, keep_screenshots? bool (false) | Connect to an existing KWin session (real desktop or container). Defaults to $DBUS_SESSION_BUS_ADDRESS and $WAYLAND_DISPLAY. Clipboard is always enabled. session_stop only disconnects without killing KWin or pre-existing apps. |
session_stop | (none) | Stop the session and clean up. For virtual sessions: terminates KWin and all apps. For live sessions: disconnects without killing KWin or pre-existing apps. |
Observation (3 tools)
| Tool | Parameters | Description |
|---|---|---|
screenshot | include_cursor? bool (false) | Capture a screenshot of the virtual display (saved as PNG, returns file path) |
accessibility_tree | app_name? str, max_depth? int (15), role? str | Get the AT-SPI2 widget tree with roles, names, states, and screen coordinates (translated from window-local coordinates via compositor-side window geometry). Use role to filter to specific element types (e.g. "button", "check box"). Non-matching elements are hidden but their children are still traversed. |
find_ui_elements | query str, app_name? str, states? list[str] | Search for UI elements by name, role, or description (case-insensitive). Returns screen coordinates suitable for mouse_click and friends. Optionally filter by AT-SPI2 states (e.g. ["focused"], ["active", "visible"]). query can be empty when filtering by states only. |
