Nothing serious here today

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

This one needs environment variables set before it will start: IRKUMO_API_KEY (irkumo API key (ir_live_...). Free sign-up: https://api.irkumo.com/account/login). The author declared them in the registry entry; get the values from the project itself.

irkumo — questions

Answers built from our own checks of this server.

Why is there no uptime for irkumo?

irkumo 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 irkumo-mcp was installed 47 times last week.

How do I connect irkumo?

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 irkumo-mcp straight from npm; nothing to host, nothing to sign up for.

How many people use irkumo?

The npm package irkumo-mcp was installed 47 times in the last week. Week over week that is -13%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is irkumo open source?

Yes — it is published under the MIT licence, written in TypeScript 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.
