## Why swiftsign_upgrade is rated Critical

This tool initiates a financial subscription commitment of $15/month by starting a Stripe checkout flow. While a human must complete the payment, the tool initiates the financial obligation and transitions the account to a paid live plan. The financial category applies because it commits financial obligations.

From the tool's own definition: "Initiate the upgrade to PRO ($15/mo flat)... Stripe checkout_url... add a card... Moves the account from sandbox (sk_test_) to live sends"

## Use case

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