Nothing serious here today

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

Is this business's website still there? Checks the apex AND www, resolves DNS over HTTPS independently of web requests, falls back to plain HTTP, and separates four things a status code conflates: the name does not resolve, the check itself failed, a recognized parked/suspended/for-sale page answers, and the site refuses bots. Read-only. Will not claim a live page belongs to a different business than the one you asked about.

Domain Liveness — questions

Answers built from our own checks of this server.

What can Domain Liveness do?
It exposes 1 tools, read directly from the server on our last check. Among them: check_domain_live. 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 Domain Liveness 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 141 ms. The bar chart above shows every period we have measured.
How do I connect Domain Liveness?
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 Domain Liveness need an API key?
No. Domain Liveness 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 Domain Liveness?
It answers our handshake in 141 ms on average, which is faster than 91% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.
Is Domain Liveness open source?
We cannot say either way: written in Go, 7 408 stars on GitHub and 79 open issues, but we could not determine the licence, and without one the code is not open source by default.
