Nothing serious here today

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

Janus — questions

Answers built from our own checks of this server.

Why is there no uptime for Janus?

Janus 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 pypi package janus-mcp-server was installed 210 times last week.

How do I connect Janus?

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 janus-mcp-server straight from pypi; nothing to host, nothing to sign up for.

How many people use Janus?

The pypi package janus-mcp-server was installed 210 times in the last week. Week over week that is -56%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is Janus open source?

Yes — it is published under the Apache-2.0 licence, written in Python, 0 stars on GitHub and 1 open issue. The source link is on this page, so you can read exactly what it does with your data before you connect it.
