Delete a quotation
AI agents call siigo_delete_quotation to permanently remove resources in Siigo MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Deletion of accounting records is irreversible and cannot be undone. In the context of a financial accounting system (Siigo), deleting quotations destroys data that may be needed for audit trails, legal compliance, or business records. This qualifies as Destructive rather than Execute because the action is inherently irreversible and the outcome is predetermined (deletion), not dependent on executing arbitrary logic.
From the tool's definition Tool name 'siigo_delete_quotation' explicitly contains 'delete', and description states 'Delete a quotation'. This irreversibly removes a quotation record from the Siigo accounting system.
