Perform basic accessibility scans on web pages for WCAG compliance.

When to choose:
- You want an agent to drive a real browser through structured accessibility snapshots instead of screenshots, so no vision model is needed.
- You need Firefox, WebKit or Edge as well as Chrome: the README's --browser option lists chrome, firefox, webkit and msedge.
- You want to test or script flows with isolated in-memory profiles (--isolated), device emulation (--device) or saved Playwright traces (--save-trace).
When to skip:
- Your main goal is debugging or performance analysis of a page; Chrome DevTools MCP exposes performance traces and network inspection as dedicated tools.
- You need proxies, CAPTCHA handling or large-scale scraping of protected sites; that is outside what the README claims for this server.
- You want to treat it as a sandbox: the project says its origin allow and block lists are not a security boundary.
