Ksef Fa3 Invoice Lint — questions

Answers built from our own checks of this server.

Why is there no uptime for Ksef Fa3 Invoice Lint?

Ksef Fa3 Invoice Lint 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 npm package @readystack/ksef-fa3-invoice-lint was installed 12 times last week.

How do I connect Ksef Fa3 Invoice Lint?

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 @readystack/ksef-fa3-invoice-lint straight from npm; nothing to host, nothing to sign up for.

How many people use Ksef Fa3 Invoice Lint?

The npm package @readystack/ksef-fa3-invoice-lint was installed 12 times in the last week. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
