explain

explain_accessibility_issue

Use this when the user asks what an axe-core accessibility rule means or how to fix it — such as color-contrast, image-alt, label or link-name. Returns plain-English steps and a code example. Do not use it when the user wants a site checked; it explains a rule and does not scan pages.

scan

scan_accessibility

Use this when the user wants a public website or web page checked for accessibility (WCAG 2.1/2.2 AA, ADA, EAA, Section 508): it loads the live page in a real browser, runs axe-core on it and up to two more same-site pages, and returns a 0-100 score, a letter grade and the failing rules with example elements. Takes 15-40 seconds. Do not use it for pages that need a login, for localhost or private-network addresses, or for pasted HTML.

RatedWithAI accessibility checker — questions

Answers built from our own checks of this server.

What can RatedWithAI accessibility checker do?

It exposes 2 tools, read directly from the server on our last check. Among them: explain_accessibility_issue, scan_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 RatedWithAI accessibility checker working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 3 of 92 checks got a reply (3.3%), average response time 328 ms. The bar chart above shows every period we have measured.

The registry lists RatedWithAI accessibility checker 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 RatedWithAI accessibility checker?

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

Does RatedWithAI accessibility checker need an API key?

No. RatedWithAI accessibility checker completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 2 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is RatedWithAI accessibility checker?

It answers our handshake in 328 ms on average, which is faster than 43% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
