AI agents use cashapp_request_money to commit financial operations through Mcp Cashapp — usually the final step of a payment, billing, or trading workflow. A call moves real money.

Misuse by an AI agent could result in unauthorized payment requests sent to contacts, causing financial and reputational harm.
