Nothing serious here today

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

Token Lens — questions

Answers built from our own checks of this server.

Why is there no uptime for Token Lens?

Token Lens 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 @kunal_dutt/token-lens.

How do I connect Token Lens?

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 @kunal_dutt/token-lens straight from npm; nothing to host, nothing to sign up for.
