Celestium: Cosmic Compass — questions

Answers built from our own checks of this server.

What can Celestium: Cosmic Compass do?

It exposes 1 tools, read directly from the server on our last check. Among them: celestium. 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 Celestium: Cosmic Compass 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 1190 ms. The bar chart above shows every period we have measured.

How do I connect Celestium: Cosmic Compass?

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 Celestium: Cosmic Compass need an API key?

No. Celestium: Cosmic Compass 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 Celestium: Cosmic Compass?

It answers our handshake in 1190 ms on average, which is faster than 5% 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.
