## Why borrow is rated Critical

This tool commits a financial obligation by borrowing tokens (USDC) from a lending pool on Polygon. Borrowing creates a debt liability that must be repaid, potentially with interest. Misuse by an AI agent could result in unauthorized loans, collateral at risk, and significant financial losses.

From the tool's own definition: "'Borrow tokens from the LendingPool with reputation-based collateral. Auto-selects the USDC pool.'"

Risk signals: Handles credentials or secrets (api_key)

## Use case

AI agents use borrow to commit financial operations through Ai Agent Bank, usually the final step of a payment, billing, or trading workflow. A call moves real money.
