Close an MPP channel. pay.sh runs settleAndFinalize + distribute atomically
AI agents use robot_close_payshell_session to commit financial operations through Execution Market — usually the final step of a payment, billing, or trading workflow. A call moves real money.
This tool closes a micropayment channel and triggers atomic settlement and fund distribution. It irreversibly finalizes financial transactions and distributes funds (USDC), making it Financial in category. The atomic and irreversible nature of channel settlement combined with fund distribution means misuse could result in incorrect or unauthorized disbursement of funds — hence critical severity.
