Discontinue an existing medication from patient records
AI agents call discontinueMedication to permanently remove resources in Medical MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Discontinuing a medication from patient records is effectively irreversible in clinical context; restoring a discontinued medication requires explicit re-prescribing. In a healthcare setting, misuse by an AI agent could cause patient harm (missed doses, treatment gaps), making the blast radius critical. The action cannot be simply undone like a typical 'update', placing it in the Destructive category over Write.
From the tool's definition "Discontinue an existing medication from patient records" — permanently removes or stops a medication entry in a patient's medical record
