withdraw
AI agents use withdraw to commit financial operations through MCP Banking Server — usually the final step of a payment, billing, or trading workflow. A call moves real money.
This is a financial tool that directly commits financial obligations by transferring funds out of accounts. It is irreversible once executed and represents the highest-severity risk category. The banking server context and sibling tools (deposit, get_balance, get_transaction_history) confirm this is a money movement operation.
From the tool's definition Tool name 'withdraw' on a MCP Banking Server that explicitly handles 'transactions (deposits/withdrawals)' and 'account management'. Despite empty description, context unambiguously indicates this tool moves money from accounts.
