Quarry — questions

Answers built from our own checks of this server.

Why is there no uptime for Quarry?

Quarry 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 quarry-db was installed 1 595 times last week.

How do I connect Quarry?

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 quarry-db straight from pypi; nothing to host, nothing to sign up for.

How many people use Quarry?

The pypi package quarry-db was installed 1 595 times in the last week. Week over week that is +96%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is Quarry open source?

Yes — it is published under the MIT licence, written in Python, 4 stars on GitHub and 6 open issues. The source link is on this page, so you can read exactly what it does with your data before you connect it.
