Tools (43)

Read from the source code; the running server may differ. Descriptions are the server’s own words; hidden characters are shown as [U+…].

  • auth_check

    Is the tab sitting on a sign-in wall? Reads the page (URL, title, password fields, sign-in controls) and returns { authRequired, confidence, signals }. Use it after a navigate, or whenever a step fails unexpectedly, to tell "the session expired" apart from "the agent got lost". Pass failOnAuthWall:true to get an [AUTH_REQUIRED] error instead of a verdict, so a harness can bucket the run as an auth failure.

  • back

    Go back in history.

  • batch

    Run multiple tool calls in one request — parallel (default) or serial. Each op is { tool, args } and goes through the same policy gate, rate limit, and error handling as a direct call. In parallel mode, tab-scoped ops MUST pass an explicit tabId (the active-tab default is unsafe under concurrency). Use to drive several tabs at once (e.g. open tabs, then batch get_text across them). Cannot be nested.

  • chrome_status

    Report backend/session status: paired browser profiles and how each was named, and flags for switched-off capabilities.

  • click

    Click an element. Target by selector, a snapshot ref, or role+name (e.g. role:"button", name:"Sign in") - the locator needs no snapshot first. trusted=true uses real OS-level input.

  • console_logs

    Console output and uncaught errors recorded on the page (requires --enable-observers). This is how you find out WHY a page misbehaved rather than only what it looks like afterwards. Pass sinceSeq to poll for what is new, clear:true to drain.

  • dialogs

    Native dialogs (alert/confirm/prompt/beforeunload) the page raised, and how they were answered (requires --enable-observers). With observers on, dialogs are intercepted rather than left to block the renderer - which is what otherwise turns a click that opens a confirm() into a mystery TIMEOUT. Set policy:'accept' to answer confirms with true.

  • download_file

    Download a file by URL or from a link element.

  • draw

    Draw freehand strokes with real mouse input. Points use CSS pixels from the top-left of the browser viewport; activate the site’s drawing tool first. Each stroke needs at least two points.

  • eval

    Evaluate JavaScript in the page (disabled in safe-mode).

  • extract_links

    Extract anchors from the page or a subtree. dedupe=true collapses links sharing an href (nav/footer noise); limit caps the count.

  • fill_form

    Fill multiple fields (keyed by selector) and optionally submit.

  • forward

    Go forward in history.

  • frames_list

    List the tab's frames (the top document plus every iframe the extension can reach), with each frame's id and URL. Use it when a selector that should match does not: the element is probably in one of these frames, and you can then pass frameId (or allFrames:true) to act inside it.

  • get_cookies

    Cookies for the tab's URL (or url); values need --enable-cookie-values.

Show 28 more tools
  • get_html

    Get HTML of the page or an element. Output is capped (see maxBytes) and cut at a tag boundary; narrow it with `selector` rather than raising the cap when you can. Password field values are always blanked.

  • get_text

    Get visible text of the page or an element.

  • hover

    Hover over an element.

  • navigate

    Navigate the agent's tab to a URL, replacing its page. With no agent's tab yet it opens one in the background: the user's own tab is only navigated when you pass its tabId.

  • network_log

    Requests the page made - fetch and XMLHttpRequest with method, URL, status and duration (requires --enable-observers). Set includeResources:true to also list scripts/images/styles from Resource Timing (those carry timing and size but no status). Does not include the document request or headers.

  • page_watch

    Save a local page checkpoint and compare it later. Actions: create (name), compare (watchId), list, delete. Stores accessibility labels and state, never form values. Site allowlist still applies.

  • press

    Press a key (with optional modifiers).

  • print_pdf

    Render the page to PDF through Chrome's own print pipeline and save it to the task's results/ dir. Returns the path and size, not the bytes - a PDF is not something to spend context on.

  • profile_rename

    Rename an automatically named browser profile (e.g. "profile-2" -> "work"). The name sticks across restarts; its saved artifacts move with it.

  • profile_use

    Switch the active browser profile (identity). Subsequent downloads, results, screenshots, and the action log are stored under profiles/<name>/. Resets the active task to "default" unless you then call task_new.

  • proxy_status

    The active profile's proxy and the IP sites see. The user sets it per Chrome profile; for another IP, profile_use another profile.

  • read_as_markdown

    Read the page (or subtree) as readable markdown.

  • reload

    Reload the active (or given) tab.

  • screenshot

    Capture a screenshot (page or element). Default is JPEG (quality 70) at CSS-pixel size, which is several times smaller than PNG and reads fine. Pass format:"png" for lossless, quality 1-100 for JPEG, scale 2 for device pixels on a Retina display or 0.5 to shrink.

  • scroll

    Scroll the page or to an element.

  • select_option

    Select option(s) of a <select> by value or visible label.

  • snapshot

    Accessibility snapshot: interactive elements with refs to target by `ref` (more reliable than guessing CSS selectors). Pass diff:true to get only what changed since the last snapshot of this tab - far cheaper in a click/read loop. Password fields appear as secret:true with no value.

  • storage

    Read/write localStorage (or sessionStorage). op: get|set|remove|clear.

  • tab_close

    Close a tab by tabId.

  • tab_new

    Open a NEW tab (optionally at a URL) in the background, leaving the user's tab alone; it becomes the agent's tab, where calls without tabId go. Pass active:true to show it to the user.

  • tab_select

    Make a tab the agent's tab by tabId, in the background: calls without tabId go to it and the user stays on their own tab. Pass show:true only to bring it to the front for the user.

  • tabs_list

    List open browser tabs.

  • task_new

    Start a new task (run) under the active profile. Creates profiles/<profile>/tasks/<name>/ with downloads/, results/, screenshots/ and makes it the active task so all captured artifacts land there.

  • task_status

    Report the active profile/task and the folder paths where this run's artifacts are stored.

  • tasks_list

    List every task across all profiles under the data dir, with sizes and download counts.

  • type

    Type text into an element (target by selector, ref, or role+name). trusted=true sends real keystrokes (works on React/Vue controlled inputs).

  • upload_file

    Set local file(s) on a file <input> (target by selector or ref) — uploads without the OS dialog. Requires --enable-uploads. `files` are absolute local paths.

  • wait_for

    Wait for a selector or text to appear/disappear.
