Scan the page for accessibility violations using axe-core. Returns WCAG violations with remediation guidance. Optionally generates an HTML report.
AI agents call accessibility_scan to retrieve information from MCP Playwright Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool reads and analyzes the current page state using axe-core to detect accessibility issues. It only retrieves data (violations and guidance) and optionally generates a report. It does not modify browser state, execute arbitrary code, or cause side effects beyond reading the DOM.
