Capabilities

Tools 2

explain_accessibility_issue

Use this when the user asks what an axe-core accessibility rule means or how to fix it — such as color-contrast, image-alt, label or link-name. Returns plain-English steps and a code example. Do not use it when the user wants a site checked; it explains a rule and does not scan pages.

Discovered 23 hr ago

scan_accessibility

Use this when the user wants a public website or web page checked for accessibility (WCAG 2.1/2.2 AA, ADA, EAA, Section 508): it loads the live page in a real browser, runs axe-core on it and up to two more same-site pages, and returns a 0-100 score, a letter grade and the failing rules with example elements. Takes 15-40 seconds. Do not use it for pages that need a login, for localhost or private-network addresses, or for pasted HTML.
