A side-by-side look at the Public Browser and Webdriverio MCP MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose Public Browser for browser automation work as a local process; choose Webdriverio MCP for browser automation as a local process. You can also run both side by side in one mcpServers block.
virtual_desk, view_page, click.enable_tools, start_session, attach_session.Rows where the two servers differ are marked.

virtual_deskList all open tabs with IDs, URLs and state. Call it first in every session, after a reconnect, or when unsure; reuse a listed tab ID instead of opening duplicates. Cheap, call liberally.view_pageSee what is on the page: text plus stable element refs for click/type/fill_form. Default filter 'interactive' lists actionable elements; for paragraphs or table cells call view_page(ref, filter: 'all'). Collapsed containers show as [eXX role, N items] — expand with view_page(ref: 'eXX', filter: 'all').clickClick an element by ref, CSS selector, visible text, or viewport x/y (canvas, pixel-precise targets). Dispatches real CDP mouse events. A click that opens a new tab is reported in the response. The DOM diff (NEW/REMOVED/CHANGED) arrives with the next page action, or here with wait_for_diff: true.typeType text into an input identified by ref or CSS selector. For 2+ fields use fill_form; for special keys (Enter, Escape, Tab, arrows) or shortcuts (Ctrl+K) use press_key.fill_formFill a whole form in one call: text inputs, <select> (by value or visible label), checkboxes (boolean) and radio buttons. One round-trip; partial errors do not abort and each field reports its own status. On per-field errors call view_page and retry the failing fields.press_keyPress a key or shortcut (Enter, Escape, Tab, arrows, Ctrl+K). Optionally focus an element first via ref or selector.scrollScroll the page, a container, or an element into view. Reports the position and content growth (scrollHeight delta — detects lazy-loaded content) and handles settle timing. Use container_ref/container_selector plus direction to scroll inside a container.dragDrag a source onto a target: HTML5 drag-and-drop (draggable lists, SortableJS, React DnD) and mouse drags (sliders, canvas, resize handles). Scrolls the source into view; says when no page reaction was detected. Source: from_ref/from_selector or from_x+from_y; target: to_ref/to_selector or to_x+to_y.navigateNavigate the active tab to a URL, or action 'back' / 'reload' (all refs become stale after reload). Waits for settle. Overwrites the user's active tab — check virtual_desk first; the first call per session is redirected to virtual_desk.switch_tabOpen a new tab, switch to a tab by ID (from virtual_desk), or close one. Prefer 'open' over navigate when the user's active tab must stay untouched. Refs from the previous tab are invalid afterwards — call view_page before acting.tab_statusActive tab's cached URL, title, ready state and errors — a cheap mid-workflow sanity check ('did my click navigate?'). Not for tab discovery or page content.wait_forWait until a condition holds: element visible, page text present, URL match, network idle, or a JS expression true. Prefer condition 'text' over a JS expression for 'has the page said X yet'. assert: true checks once and fails instead of waiting.enable_toolsAdd a group of tools: `mocks`, `cookies`, `device`, `extensions`, `attach`, `elements`, `cloud-appsstart_sessionStart a browser, local Electron application, or mobile app session; `attach: true` retains the existing Chrome CDP connection modeattach_sessionAttach to an existing remote WebDriver/Appium session by ID without creating a new sessionlaunch_chromeLaunch a new Chrome instance with remote debugging enabled (for use with `start_session({ attach: true })`)close_sessionClose or detach from the current session (supports `detach: true` to disconnect without terminating)emulate_deviceEmulate a mobile/tablet device preset (viewport, DPR, UA, touch); requires BiDi sessionopen_web_extensionInstall a web extension through WebDriver BiDi and open one of its extension pages so normal page tools can drive its UInavigateNavigate to a URL.

We only show a config when the install command is confirmed.
