Nothing serious here today

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

brain-core — questions

Answers built from our own checks of this server.

Why is there no uptime for brain-core?

brain-core 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 brain-core-mcp was installed 3 882 times last week.

How do I connect brain-core?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It runs locally, so the command pulls brain-core-mcp straight from pypi; nothing to host, nothing to sign up for.

How many people use brain-core?

The pypi package brain-core-mcp was installed 3 882 times in the last week. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is brain-core open source?

Yes — it is published under the MIT 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.
