Nothing serious here today

Today is the operative word: we check 402index every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

402index — questions

Answers built from our own checks of this server.

Why is there no uptime for 402index?

402index 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 @402index/mcp-server was installed 84 times last week.

How do I connect 402index?

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 @402index/mcp-server straight from npm; nothing to host, nothing to sign up for.

How many people use 402index?

The npm package @402index/mcp-server was installed 84 times in the last week. Week over week that is +22%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is 402index open source?

Yes — it is published under the MIT licence, written in JavaScript, 0 stars on GitHub and 16 open issues. The source link is on this page, so you can read exactly what it does with your data before you connect it.
