## Why servicenow_custom_api is rated High

The tool name suggests it calls custom/arbitrary ServiceNow API endpoints. Without a description, the exact behavior is unknown, but 'custom API' implies executing arbitrary operations against ServiceNow which could span read, write, or destructive actions. Given the potential blast radius of arbitrary API calls in an enterprise ITSM system, Execute is the most appropriate category at high severity.

From the tool's own definition: "Tool name 'servicenow_custom_api' - description is empty and uninformative"

## Use case

AI agents invoke servicenow_custom_api to trigger actions in Servicenow Api. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.
