Nothing serious here today

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

Knowledge Graph RDBMS — questions

Answers built from our own checks of this server.

Why is there no uptime for Knowledge Graph RDBMS?

Knowledge Graph RDBMS 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 knowledge-graph-rdbms was installed 117 times last week.

How do I connect Knowledge Graph RDBMS?

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 knowledge-graph-rdbms straight from pypi; nothing to host, nothing to sign up for.

How many people use Knowledge Graph RDBMS?

The pypi package knowledge-graph-rdbms was installed 117 times in the last week. Week over week that is +4%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is Knowledge Graph RDBMS open source?

Yes — it is published under the MIT licence, written in Python and 1 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.
