Available tools 5

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

site

check_site

Live up/down check of any public website from an independent server (Singapore; Boston for sites that geo-block Singapore). Returns a one-sentence verdict plus status code, latency, resolved IP, redirect target, the view from the other region when available, and how many users reported problems in the last hour. Results are cached 30 s per domain.

site_history

Uptime percentage over 24 h and over the requested window (up to 7 days), the list of outages in that window, when the site was last seen down, the current state and user-report counts. Only for monitored sites (see list_monitored_sites); use check_site for anything else.

certificate

check_certificate

Reads the HTTPS certificate of a public domain and reports days until expiry, the expiry date and the issuer.

monitored

list_monitored_sites

The 634 sites checked every 5 minutes, grouped in 17 categories. Without arguments returns the category list with counts; filter by category or a text query to get domains (at most 200 per call).

outages

list_outages

Lists the monitored sites (634 across 17 categories) that are confirmed down right now: two consecutive failed checks from their home region and no other region seeing them up in the last 15 minutes. Optional category filter.

Is This Site Down? — questions

Answers built from our own checks of this server.

What can Is This Site Down? do?

It exposes 5 tools, read directly from the server on our last check. Among them: check_certificate, check_site, list_monitored_sites, list_outages, site_history. 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 Is This Site Down? working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 686 ms. The bar chart above shows every period we have measured.

How do I connect Is This Site Down??

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 Is This Site Down? need an API key?

No. Is This Site Down? completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 5 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Is This Site Down??

It answers our handshake in 686 ms on average, which is faster than 13% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
