WHAT IT DOES

What create_subscription_plan does on PayPal

AI agents use create_subscription_plan to create or update resources in PayPal, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your PayPal environment.

RISK

Why create_subscription_plan is rated Medium

This tool creates a new subscription plan, which is a write operation that modifies financial configuration. However, it is categorized as Write rather than Financial because it creates the plan template itself, not the financial transaction. The plan becomes a template for future Financial transactions (charges).

From the tool's definition Tool name 'create_subscription_plan' and description 'Create a new subscription plan' indicate irreversible creation of a financial product that will govern recurring billing.
