WHAT IT DOES

What returns_cancel does on ServiceTitan MCP Server

AI agents call returns_cancel 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 returns_cancel is rated Critical

Cancellation operations typically cannot be reversed without manual intervention and create audit trail issues. In a financial/business context like ServiceTitan, canceling returns affects inventory reconciliation, financial statements, and customer records. While the description is empty (lowering confidence slightly), the function name strongly suggests a destructive action.

From the tool's definition Tool name 'returns_cancel' indicates cancellation of returns, which irreversibly modifies or voids a return transaction.
