Return a deposit to the depositor (callable by the provider). Use when the depositor met all terms.
AI agents use return_deposit to commit financial operations through Remit Md MCP Server — usually the final step of a payment, billing, or trading workflow. A call moves real money.
This tool transfers money (returns a deposit) and commits a financial obligation. Even though the operation is conditional ('when the depositor met all terms'), it fundamentally moves funds, making it Financial category. The severity is high because misuse could result in unauthorized fund transfers, though the conditional nature and legitimate refund purpose prevent it from being critical.
From the tool's definition Tool is part of remit.md MCP Server which 'Enables AI agents to perform financial transactions such as direct payments, escrows, and bounty management' and 'return_deposit' returns funds to a depositor—a direct money movement operation.
