Setup: Jithox E-Invoice in ChatGPT

ChatGPT adds MCP servers via custom connectors in developer mode. The gateway route takes about two minutes:

  1. Connect Jithox E-Invoice to your free gate gateway from the verified directory.
  2. Open ChatGPT → Settings → Connectors and enable Developer mode under Advanced.
  3. Click 'Create', name it 'gate', paste your gateway URL, and set authentication to OAuth.
  4. Approve the authorization — Jithox E-Invoice is now available in your ChatGPT conversations.

What to ask once it’s connected

“Validate this draft invoice against EU BIS 3.0 before I send it.”
“Check whether VAT number BE0123456789 is valid in VIES.”
“Look up whether this supplier is a Peppol participant.”
“List every reason this invoice would fail e-invoicing validation.”
