MCP Afip runs on your own machine — the client starts it, so there is no endpoint to ping. 25 installs a week from npm. Last commit 29 Aug 2026.
AFIP — Argentine tax authority, electronic invoicing (Factura Electrónica)
Today is the operative word: we check MCP Afip 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.

AFIP_CERT_PATH (Path to AFIP certificate (.crt)), AFIP_KEY_PATH (Path to AFIP private key (.key)), AFIP_CUIT (CUIT number).
