Tools & capabilities
Kwin MCP tools 30
session_startStart an isolated KWin Wayland session, optionally launching an app. A screen size of `0` auto-detects the bounding box of the logical desktop (all enabled outputs / connected monitors). Set `enable_clipboard=true` to enable clipboard tools (requires `wl-clipboard`). Set `keep_screenshots=true` to…session_connectConnect 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_stopStop the session and clean up. For virtual sessions: terminates KWin and all apps. For live sessions: disconnects without killing KWin or pre-existing apps.screenshotCapture a screenshot of the virtual display (saved as PNG, returns file path)accessibility_treeGet 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 stil…find_ui_elementsSearch 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.mouse_clickClick at coordinates. Supports left/right/middle, single/double/triple click, modifier keys (e.g. `["ctrl", "shift"]`), and long-press via `hold_ms`.mouse_moveMove the cursor (hover) to coordinates without clickingmouse_scrollScroll at coordinates. `delta` positive = down/right, negative = up/left. Use `discrete=true` for wheel ticks, `steps` to split into smooth increments.mouse_dragDrag from one point to another with smooth interpolation. Supports custom `waypoints` for complex drag paths.mouse_button_downPress a mouse button at coordinates without releasing. Use with `mouse_button_up` for manual drag control.mouse_button_upRelease a previously pressed mouse button at coordinates- +18 more on the listing page
