## Why update_catalog_item is rated Medium

This tool creates or modifies data reversibly by updating an existing catalog item in ServiceNow. It does not delete, execute code, move money, or trigger uncontrolled external operations.

From the tool's own definition: "Tool name 'update_catalog_item' and description 'Update an existing catalog item' explicitly indicate modification of data. The requirement note '(requires WRITE_ENABLED=true)' confirms this is a write operation."

## Use case

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