Nothing serious here today

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

Celestial Node — questions

Answers built from our own checks of this server.

Why is there no uptime for Celestial Node?

Celestial Node runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the npm package celestialnode-mcp.

How do I connect Celestial Node?

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 runs locally, so the command pulls celestialnode-mcp straight from npm; nothing to host, nothing to sign up for.

Is Celestial Node open source?

Yes — it is published under the MIT licence, written in JavaScript and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
