Nothing serious here today

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

Guard Core — questions

Answers built from our own checks of this server.

Why is there no uptime for Guard Core?

Guard 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 guard-core-mcp was installed 899 times last week.

How do I connect Guard 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 guard-core-mcp straight from pypi; nothing to host, nothing to sign up for.

How many people use Guard Core?

The pypi package guard-core-mcp was installed 899 times in the last week. Week over week that is -42%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is Guard Core open source?

Yes — it is published under the MIT licence, written in Python and 2 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.
