## Why create_update_schema_file is rated Medium

This tool creates or modifies schema files within Postman, which is a reversible operation. It does not delete data (ruling out Destructive), does not execute arbitrary code (ruling out Execute), involves no financial transactions (ruling out Financial), and actively modifies state rather than merely reading (ruling out Read).

From the tool's own definition: "Tool name is 'create_update_schema_file' and description states 'Create or update a schema file'. The words 'create or update' directly indicate reversible data modification."

## Use case

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