WHAT IT DOES

What create_price does on Stripe

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

RISK

Why create_price is rated Medium

This tool creates a new pricing record, which is a write operation. While pricing changes can affect billing downstream, the action itself is reversible (prices can be deleted or superseded). The sibling tools include financial operations (create_refund, create_invoice) which are more severe, so this is classified as Write rather than Financial.

From the tool's definition Tool name is 'create_price' and description states 'Create a new price for a product'. The verb 'create' indicates reversible creation of data (pricing information).

RECOMMENDED RULE

The rule that runs create_price safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Stripe, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For create_price, this is the rule to start with:

create_price Rate-limited

create_price stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
