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 in the form 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.
