Nothing serious here today

Today is the operative word: we check Structured Data Check every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

run

Structured data validator in one call: extracts JSON-LD, microdata and RDFa from a URL or raw HTML, then reports the required and recommended Google Rich Results fields missing per @type. Covers the three syntaxes programmatically, where the reference validators are manual web tools with no public API.

Structured Data Check — questions

Answers built from our own checks of this server.

What can Structured Data Check do?

It exposes 1 tools, read directly from the server on our last check. Among them: run. 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 Structured Data Check working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 411 ms. The bar chart above shows every period we have measured.

How do I connect Structured Data Check?

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 Structured Data Check need an API key?

No. Structured Data 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.

How fast is Structured Data Check?

It answers our handshake in 411 ms on average, which is faster than 30% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
