three.ws Brain — questions

Answers built from our own checks of this server.

Why is there no uptime for three.ws Brain?
three.ws Brain 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 @three-ws/brain-mcp was installed 33 times last week.
How do I connect three.ws Brain?
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 @three-ws/brain-mcp straight from npm; nothing to host, nothing to sign up for.
How many people use three.ws Brain?
The npm package @three-ws/brain-mcp was installed 33 times in the last week. Week over week that is -40%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is three.ws Brain open source?
Yes — it is published under the NOASSERTION licence, written in JavaScript, 92 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.
