Submit the order and return the payment URL.
AI agents use complete_checkout to commit financial operations through Aareguru MCP Server — usually the final step of a payment, billing, or trading workflow. A call moves real money.
This tool finalizes a purchase order and generates a payment URL, which constitutes committing a financial obligation. It is the most severe applicable category. The presence of sibling tools 'create_checkout_session' and 'cancel_checkout_session' further confirms this is part of a payment flow. Misuse could result in unauthorized financial transactions.
From the tool's definition 'Submit the order and return the payment URL' — initiates a financial transaction by completing a checkout/order submission
