Nothing serious here today
Today is the operative word: we check Explorium every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Explorium — questions
Answers built from our own checks of this server.
Why is there no tool list for Explorium?
The server answered our handshake with an authorization challenge, so it is running — but it will not describe its tools to an anonymous client. To see them you need to connect with your own credentials. We record it as alive, not as broken: 100.0% of checks in the last 24 hours got a reply.
Is Explorium 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 252 ms. The bar chart above shows every period we have measured.
How do I connect Explorium?
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. You will need your own key: it refuses anonymous clients.
Does Explorium need an API key?
Yes. Every time we knock, Explorium answers with an authorization challenge instead of its tool list — that is how we know it is running and gated rather than broken. Bring your own credentials and it will talk.
How fast is Explorium?
It answers our handshake in 252 ms on average, which is faster than 56% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
