Nothing serious here today

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

Available tools 4

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

explain

explain_check

Explain one Site Check check by its id (as returned by scan_website): what it measures, the pass and fail thresholds, why it matters, how to fix it, and the typical effort. Static reference, no network access.

readiness

check_ai_search_readiness

Check whether AI assistants and answer engines can read and quote a public website: which AI crawlers (GPTBot, ClaudeBot, PerplexityBot, Google-Extended and others) its robots.txt allows or blocks, whether it publishes llms.txt, which structured data types it declares, how its title and description read, and the search and AI checks with fixes. Shares the 24 hour cache with scan_website.

scan

scan_website

Run a measured health check of a public website homepage: speed (server response, page weight, scripts, image formats), security (HTTPS, certificate expiry, security headers), domain registration expiry, email authentication (MX, SPF, DMARC), search basics (title, description, headings, indexability, sitemap), AI search readiness (structured data, AI crawler rules, llms.txt) and contact paths (tap to call, forms, analytics). Every result is measured, not judged by a model, and each warn or fail comes with a fix and an effort level. Returns a 0 to 100 website score, the top fixes, and how the page appears in a search result. Results are cached for 24 hours. Use detail "full" to include passing checks.

score

score_local_presence

Score a local business on three pillars, website (45 percent), Google reviews (30 percent) and Google Business Profile (25 percent), and return an overall 0 to 100 score, a letter grade, each pillar with its verdict, and the top fixes. The website pillar comes from a live scan when a website is given. Review and profile facts (rating, review count, phone, address, hours) are supplied by the caller from the user or from a public listing; this tool does not look them up. A pillar with no facts is marked unknown and left out of the overall score rather than scored as zero.

Site Check — questions

Answers built from our own checks of this server.

What can Site Check do?

It exposes 4 tools, read directly from the server on our last check. Among them: check_ai_search_readiness, explain_check, scan_website, score_local_presence. 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 Site Check working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 12 of 12 checks got a reply (100.0%), average response time 352 ms. The bar chart above shows every period we have measured.

How do I connect Site 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 Site Check need an API key?

No. Site Check completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 4 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Site Check?

It answers our handshake in 352 ms on average, which is faster than 39% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
