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

  • annotate

    Open a web page with hover annotations. Returns a proxy URL that adds interactive element labels to any page. User opens this URL in any browser to see annotations on hover.

  • get_elements

    Get all UI elements detected on the currently annotated page. Returns element names, CSS selectors, positions, and sizes. Use this to understand what the user is referring to when they describe a UI element.

  • highlight_element

    Briefly flash-highlight a specific element on the page so the user can see which element you are referring to. Useful for confirming "do you mean this element?"

  • inspect_mode

    Toggle inspect mode on the annotated page. When ON, the user can click any element to copy its name. When OFF, the page behaves normally. Use this to help the user copy element names for communicating design changes.

  • rescan_elements

    Force the annotated page to rescan all UI elements. Use this after the page content has changed (e.g. after navigation, DOM updates, or user interaction).
