šŸ‘¾ Using AccessibilityChecker.org in Claude, ChatGPT, Cursor and VS Code

Discover how to run an accessibility scan of a website from inside your AI assistant or coding tool.

Run an accessibility scan of any website from inside your AI assistant or coding tool, get every issue with a fix instruction, and let your coding agent fix the code.

Same scanner as AccessibilityChecker.org, no download.

What it does

  • Scans one page or a whole site against WCAG 2.2 (ADA, EAA, Section 508).

  • Returns a score, every failing element, its severity, the WCAG rule and a fix instruction.

  • In coding tools (Claude Code, Codex, Cursor, VS Code), ask the agent to fix the issues and re-scan.

  • Results are also saved to your AccessibilityChecker.org dashboard when you are signed in.

Free limits

  • Without an account: a few scans to try it.

  • Free account: 5 scans per day. Sign in from the assistant when it asks.

  • Paid plans: scan whole sites, more pages per day, and keep results in the dashboard. See https://www.accessibilitychecker.org/pricing/.

Server address

If your tool asks for a URL, use:

https://mcp.accessibilitychecker.org/mcp-app
