Tools & capabilities
BRYG tools 43
browser_tabsList tabs across all browsers (chrome / edge) with ids, grouped by browser and window.browser_new_tabOpen a new tab (optionally at url); it becomes the current tab. browser: chrome / edge (default: the current browser; launched automatically if not running). window: "current" (default: the window of the current tab), "new" (a new window), or a window id from browser_tabs. isolated=true opens a new window with its own cookies / login state, so different accounts can be signed in at once (gone when the browser closes). Afterwards any tool given that page id is routed to its browser automatically.browser_close_tabClose the given tab.browser_activate_tabBring the given tab to the foreground.browser_navigateNavigate to a URL.browser_reloadReload the page.browser_go_backGo back in history.browser_go_forwardGo forward in history.browser_page_infoReturn url/title/viewport/scroll.browser_snapshotAccessibility-tree snapshot; interactive elements are tagged [ref=N]. On large pages use interactive_only=true (interactive elements only) or query (only lines containing the string) to save tokens; ref numbers stay stable under filtering.browser_click_textClick the element with the given visible text (text-based targeting is more reliable than coordinates; great for cookie banners, popups and buttons, e.g. 'OK').browser_login_fillFill login credentials without exposing them to the conversation. Pass credsFile (path to a credentials file: JSON / key=value / two lines / one line) or user+pass directly; visible username/password fields are auto-detected (override with *Selector). Fills only, never submits - press the login button with click_text afterwards.- +31 more on the listing page
