## Why pay_fund is rated Critical

This tool facilitates depositing USDC cryptocurrency into a wallet, which constitutes a financial operation involving money movement. While the deposit itself is initiated by the user (not the tool moving funds directly), generating a funding link is a critical step in financial transactions. Misuse by an AI agent could lead to unauthorized wallet funding or financial commitment.

From the tool's own definition: "Tool name 'pay_fund' combined with description 'Generate a funding link to deposit USDC into your wallet' indicates direct financial operations. Server context shows this is part of a USDC payments system for AI agents on Base blockchain."

## Use case

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