accessibility

check_accessibility

Audit one web page for accessibility problems using a real browser. Runs axe-core (WCAG 2.1 AA) plus checks that standard scanners do not perform: controls that look clickable but cannot be operated by keyboard, error messages not programmatically linked to their field, CAPTCHA barriers, duplicate main landmarks, and missing skip links. Returns findings WITH the code change that fixes each one. Use this when someone asks whether a site is accessible, whether it meets WCAG or the European Accessibility Act, or whether keyboard and screen-reader users can operate its controls.

A11y Check — questions

Answers built from our own checks of this server.

What can A11y Check do?

It exposes 1 tools, read directly from the server on our last check. Among them: check_accessibility. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is A11y Check working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 0 of 92 checks got a reply (0.0%), average response time 79 ms. The bar chart above shows every period we have measured.

The registry lists A11y Check as active — why does it not respond?

The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.

How do I connect A11y Check?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does A11y Check need an API key?

No. A11y Check completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 1 of them are readable on this page. This is what we observed, not what the docs claim.
