## Why close_tab is rated Critical

This tool finalizes and settles a metered payment tab, which directly commits financial obligations and moves money. Settlement is typically irreversible once processed, placing this firmly in the Financial category. The broader server context (payments, escrows, fund streaming) confirms financial operations. Misuse by an AI agent could result in unintended financial settlements.

From the tool's own definition: "'Close and settle a metered payment tab' — closing and settling a tab constitutes finalizing a financial transaction and committing payment obligations"

## Use case
