inspect_element
Bounding rect, computed styles (default layout/color set or explicit styleprops), classList and attributes — for visual/layout QA without executejs getComputedStyle snippets.
How to use it
inspect_element is exposed by the Tauri Plugin MCP MCP server. Add the server to your MCP client (Claude Desktop, Cursor, Windsurf and others), and the inspect_element tool becomes available to the model automatically. See the full listing for setup details and every tool this server provides.

Calls helpers the host app registered via window.MCPBRIDGE.register(name, fn, description) — list to discover, call to invoke (async supported, results serialized + truncated). The sanctioned path to app state instead of executejs against internals.
Clicks via selector (ref, id, class, css, tag, text) or at raw x/y coordinates. Selector-based left clicks dispatch synthetic pointer events at the element (no OS permissions needed); right/middle/double and raw x/y clicks use native clicking. scopeselector/match/nth disambiguate repeated matches.
Synthetic pointer/mouse gesture chains (click, dblclick, down, up, hover, drag) on the exact matched element, no retargeting. Element-relative offset for canvas hit-testing; drags interpolate moves on the element and document (d3-drag compatible). Events are isTrusted=false.
Runs arbitrary JavaScript in the webview. Returns the last expression's value; promises are awaited. The universal escape hatch.
Inserts begin/end markers into the log buffer so querylogs can return exactly the logs produced by an action.
Tauri IPC access: invoke any #[tauri::command] with JSON args through the app's real IPC path, inspect captured webview↔Rust invoke traffic (names, args/result previews, latency, error rates), and drive events — emit fires one, armevent registers a background listener before you act (arm → act → che
localStorage operations (get/set/remove/clear/keys) and cookie management (get/clear).
Window control (list/focus/minimize/maximize/close/position/size/fullscreen), zoom, devtools, and webview state management.
Non-click mouse actions: hover, scroll (by direction/amount/to element/to top/bottom), drag (start to end coordinates).
Webview navigation: goto (URL), back/forward (with optional delta), reload.
Presses keyboard keys the typing tools can't express: Escape, Enter, Tab, arrows, Backspace/Delete, F-keys, and modifier chords (cmd+a). Emulates default actions (Enter submits, Tab moves focus) unless the app prevents them.
Queries buffered app logs (Rust log!() output, webview console. calls, and intercepted dialogs) with level/source/substring filters, pagination, and a summary mode.
Inspects the current page. Modes: map (structured element refs), html (raw DOM), state (URL/title/scroll/viewport), findelement (CSS pixel coordinates for clicking), appinfo (app metadata, windows, monitors).
Reads visible text of elements matching a CSS selector: per-element {tag, text, visible, attrs?}, whitespace-collapsed, output hard-capped with a truncated flag. The structured replacement for executejs text-scraping snippets.
Restarts the Tauri application and waits for it to come back online. Force-kills a frozen app (IPC mode only). Refuses under tauri dev — restarting would orphan the app outside the dev supervisor; reload the frontend with navigate instead.
Captures a screenshot of an application window. Saves full image to disk with small thumbnail inline (optimized for token efficiency).
Types text into the page. Supports a fields array for bulk form fill, selector targeting, or typing into the focused element. Selects options in <select> dropdowns by value or label, and attaches files to <input type="file"> via a files array. Works with inputs, textareas, contentEditable, React, Le
Waits for a condition: text appearing/disappearing, element visible/hidden/attached/detached. Useful after async content loads.
