scan_pagePerforms a comprehensive accessibility scan on the current page using Axe-core.audit_siteCrawls and scans multiple internal pages, then aggregates violations across the site.scan_page_matrixRuns Axe scans on the same page across viewport/media/zoom variants and compares deltas against baseline.audit_keyboardAudits real keyboard focus behavior by pressing Tab (and optional Shift+Tab) with practical heuristics.audit_screen_readerInspects the browser's accessibility tree (`page.ariaSnapshot`), accessible names and element geometry for potential accessibility issues. No actual screen reader is installed or driven, and its announcements and interactions are not tested.browser_navigateNavigate to a URL.browser_navigate_backGo back to the previous page.browser_navigation_timeoutSet default navigation timeout for existing tabs.browser_default_timeoutSet default operation timeout for existing tabs.browser_snapshotCapture accessibility snapshot of the current page (better than screenshot for analysis).browser_findSearch the current page accessibility snapshot without returning the full snapshot.browser_clickPerform click on a web page element.- +30 more on the listing page
