Bernstein — questions

Answers built from our own checks of this server.

Why is there no uptime for Bernstein?
Bernstein 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 bernstein was installed 47 982 times last week.
How do I connect Bernstein?
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 bernstein straight from pypi; nothing to host, nothing to sign up for.
How many people use Bernstein?
The pypi package bernstein was installed 47 982 times in the last week. Week over week that is +1%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is Bernstein open source?
Yes — it is published under the Apache-2.0 licence, written in Python, 778 stars on GitHub and 74 open issues. The source link is on this page, so you can read exactly what it does with your data before you connect it.
