MCP Ksef Pl runs on your own machine — the client starts it, so there is no endpoint to ping. 942 installs a week from pypi. Last commit 12 Sep 2026.
Polish e-invoicing MCP: KSeF API v2, FA(3)/FA(2) XML, Peppol BIS 3.0, NIP/REGON validation.
Today is the operative word: we check MCP Ksef Pl every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.
