Requirements

FAQ

Can Claude create or change invoices?

No. Every tool is read-only; the connector never calls an insert, update, delete or cancel endpoint.

Why does it need my Moloni password?

Moloni's API authenticates with the developer application plus the user's own login (OAuth password grant). The credentials are validated once and stored encrypted; the connector keeps the short-lived access token only in memory.

How is 'overdue' computed?

An invoice is open when its total exceeds the amount Moloni has reconciled against receipts, and overdue when its due date is before the reference day (today by default). Credit notes are not deducted.

Why is the unpaid summary more expensive?

Moloni's invoice list does not include the paid amount, so the connector opens each issued invoice of the period (up to 300 per call) to compute what is outstanding.

What about supplier invoices or credit notes?

This version reads sales invoices, customers and products only.
