Nothing serious here today

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

This endpoint answered with an authorization challenge. The server is running, but it did not say what kind of credentials it expects.

CloudScale-Sim — questions

Answers built from our own checks of this server.

Why is there no tool list for CloudScale-Sim?

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 CloudScale-Sim 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 95 ms. The bar chart above shows every period we have measured.

How do I connect CloudScale-Sim?

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. You will need your own credentials: it refuses anonymous clients.

Does CloudScale-Sim need an API key?

Yes. Every time we knock, CloudScale-Sim 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 CloudScale-Sim?

It answers our handshake in 95 ms on average, which is faster than 84% 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.
