Delete a unit.
AI agents call mealie_units_delete to permanently remove resources in Mealie MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The tool permanently removes a unit record from the Mealie system. While the blast radius is constrained (units are reference data rather than core recipes or meal plans), deletion cannot be undone and could disrupt meal planning if units are referenced by recipes. This is clearly Destructive, not merely Write, as the operation is irreversible.
From the tool's definition Tool name contains 'delete' and description states 'Delete a unit.' This is an irreversible deletion operation.
