  • browser_closeClose the page
  • browser_resizeResize the browser window
  • browser_console_messagesReturns all console messages
  • browser_handle_dialogHandle a dialog
  • browser_emulate_mediaEmulate CSS media features for the page, for example switch between the light and dark color scheme. Omitted parameters are left unchanged; null clears an override.
  • browser_evaluateEvaluate JavaScript expression on page or element
  • browser_file_uploadUpload one or multiple files
  • browser_dropDrop files or MIME-typed data onto an element, as if dragged from outside the page. At least one of "paths" or "data" must be provided.
  • browser_findSearch the accessibility snapshot of the current page for text or a regular expression. Returns matching snapshot nodes with a few lines of surrounding context (like search snippets), each shown under its path from the root of the tree, which is cheaper than capturing the whole snapshot when you only need to locate an element and its ref.
