AI agents use create_payment_and_apply to commit financial operations through Filevine — usually the final step of a payment, billing, or trading workflow. A call moves real money.
This tool creates payment records and applies them to invoices, which constitutes a financial transaction. Even if the payment itself may not immediately transfer funds, recording and applying payments to invoices represents a committed financial obligation and alters the accounting state of the system. The high severity reflects that misuse could result in incorrect payments, duplicate charges, or financial fraud.
From the tool's definition Tool name explicitly includes 'create_payment' and description states 'Record a payment and apply it to an invoice' — these are direct financial operations that move money or commit financial obligations.
