What the code does

We read the source, 7 d ago · rules 3dff92dd89df

Evidence

Things with no honest explanation: a promise that contradicts the code, code that runs at install time while hiding what it does, data leaving the machine.

Claims read-only, but the code runs commands src/quarry/cli.py:464, [пакет] src/quarry/cli.py:464
                proc = subprocess.run(cmd, capture_output=True, text=True, timeout=15)
Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

                proc = subprocess.run(cmd, capture_output=True, text=True, timeout=15)

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

We found things in this code

Code changes quietly between releases, and nobody reads the diff of a dependency. We do, on every release — watch Quarry and you get told the day something new turns up.

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 166 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 166 times in the last week. Week over week that is -80%. 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.
