Run an accessibility audit on the current page
AI agents call runAccessibilityAudit to retrieve information from BrowserTools MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
An accessibility audit reads and analyzes the DOM and page content to report on accessibility compliance. It produces a report but does not modify data, execute user-defined code, or cause side effects. Similar to other audit tools on this server (runPerformanceAudit, runBestPracticesAudit), it is a passive inspection tool.
From the tool's definition 'Run an accessibility audit on the current page' - this is an analysis/read operation that examines the page for accessibility issues without modifying anything
