Invapi MCP runs on your own machine — the client starts it, so there is no endpoint to ping. 34 installs a week from npm. Last commit 22 Feb 2026.
Extract, create, convert & validate invoices (UBL, CII, XRechnung, ZUGFeRD, PDF, Excel)
Today is the operative word: we check Invapi MCP every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
