## Why ghl_create_shipping_carrier is rated Medium

This tool creates a new shipping carrier entry, which is reversible (can be updated or deleted). It does not execute arbitrary code, delete data permanently, move money, or trigger external operations. It belongs to the Write category as a data creation action. The impact is limited to adding a configuration option for shipping calculations, making it low severity.

From the tool's own definition: "Tool name 'create_shipping_carrier' and description 'Create a new shipping carrier for dynamic rate calculation' indicate creation of new data (configuration/settings entry) without destructive deletion or code execution."

## Use case

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