What the code does

We read the source, 23 h ago · rules ccca72095570

In the project's build, not in the package

Found in continuous integration, deployment or infrastructure files, or in a neighbouring package of the same monorepo. None of this is installed when you add the server: it describes how the project is built and released. We list it because a leaked key in a build pipeline is still a real problem, but it is not something this server does on your machine.

Builds a database query by concatenation .github/workflows/data-refresh.yml:167

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

Nothing serious here today

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

eCFR — questions

Answers built from our own checks of this server.

Why is there no uptime for eCFR?
eCFR runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone.
Is eCFR open source?
Yes — it is published under the MIT licence, written in Python and 24 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.
