focus_window
Bring a window to the foreground by partial title match. Activate Chrome/Edge tabs by URL substring before focusing for accurate window activation.
Instructions
Bring a window to the foreground by partial title match (case-insensitive). Use when a tool does not accept a windowTitle param, or when you need to switch focus before a sequence of actions. Use chromeTabUrlContains to activate a specific Chrome/Edge tab by URL substring before focusing — only the active tab's title appears in the windows list. If CDP is unavailable, chromeTabUrlContains is silently skipped — check response.hints.warnings. Returns WindowNotFound if no match exists; call desktop_discover to see available titles. Caveats: On some apps focus may be immediately stolen back (modal dialogs, UAC prompts) — verify with desktop_state after focusing. Win11 foreground refusal (UIPI cross-elevation / admin-only target / call from a background process or service) returns code:'ForegroundRestricted' ok:false instead of silently failing — recover by switching to a tool that does not require foreground transfer: desktop_act / click_element use UIA InvokePattern (no foreground needed); keyboard BG path bypasses foreground for terminal-class targets only (Windows Terminal / cmd / PowerShell — keyboard with windowTitle on non-terminal apps still hits the same ForegroundRestricted refusal). browser_* tools target by tabId/selector, not windowTitle.
Input Schema
| Name | Required | Description | Default |
|---|---|---|---|
| title | Yes | Partial window title to search for (case-insensitive) | |
| cdpPort | No | CDP port for chromeTabUrlContains (default 9222) | |
| include | No | Optional response-shape opt-in. `['envelope']` returns the self-documenting envelope (`_version` / `data` / `as_of` / `confidence`). `['raw']` forces raw shape (overrides DESKTOP_TOUCH_ENVELOPE=1 server default). Default behaviour is raw shape (compat with existing clients). | |
| forceFocus | No | When set, use AttachThreadInput-based foreground escalation on the first attempt. When omitted (default), focus_window first tries the standard SetForegroundWindow path and auto-escalates to force-focus only if Win11 refused the default attempt (issue #197). Override env: DESKTOP_TOUCH_FORCE_FOCUS=1 sets the implicit default to true. If both default and force paths fail, focus_window now returns ok:false code:'ForegroundRestricted' instead of the previous silent ok:true with windowChanged:false. | |
| chromeTabUrlContains | No | When set, activate the Chrome/Edge tab whose URL contains this substring before focusing the window. Requires Chrome/Edge running with --remote-debugging-port (default 9222). Use this when the target is a Chrome tab that is not currently active — the active tab title is the only one visible in the window title list. |
