WHAT IT DOES

What categories_delete does on ServiceTitan MCP Server

AI agents call categories_delete to permanently remove resources in ServiceTitan MCP Server, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

RISK

Why categories_delete is rated Critical

The 'delete' action is inherently destructive - it removes data that cannot be automatically restored. In a ServiceTitan business management context, deleting categories could affect operations, reporting, and linked records. While the empty description introduces some uncertainty (hence confidence of 0.85 rather than higher), the explicit 'delete' naming convention is a clear indicator of destructive capability.

From the tool's definition Tool name contains 'delete' verb, and the lack of description combined with naming pattern of sibling tools (get, get_list, update operations) strongly suggests this is a data deletion operation.
