initiate_refund
AI agents use initiate_refund to commit financial operations through Paytm MCP Server — usually the final step of a payment, billing, or trading workflow. A call moves real money.
Initiating refunds directly moves money and commits financial obligations. Even without explicit description, the tool name combined with the payment/transaction context of the server makes this unambiguously a financial operation. This is the most severe category and poses critical risk if an AI agent invokes it without proper authorization or against legitimate transactions.
From the tool's definition Tool name 'initiate_refund' on Paytm MCP Server; server context involves 'managing Paytm payment links and transactions' and sibling tools include 'check_refund_status' and 'fetch_refund_list', confirming financial transaction management.
