This one has been quiet for a while

Quiet is not dead — but it is worth knowing when it wakes up, or when someone else takes it over. We watch the repository and tell you either way.

Cortex — questions

Answers built from our own checks of this server.

Why is there no uptime for Cortex?
Cortex 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 abbacus-cortex was installed 260 times last week.
Is Cortex still maintained?
The linked repository no longer exists on GitHub — it was deleted or made private. We show this because it changes what you can expect: an unmaintained server may keep answering for months and then stop without warning.
How do I connect Cortex?
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 abbacus-cortex straight from pypi; nothing to host, nothing to sign up for.
How many people use Cortex?
The pypi package abbacus-cortex was installed 260 times in the last week. Week over week that is -19%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
