Get the primary therapeutic alternative when a drug is unavailable.
AI agents call get_alternative to retrieve information from MCPDischarge without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries a pharmaceutical database to retrieve alternative drug options for clinical decision support. It is a read-only lookup operation with no side effects on patient records, inventory, or financial systems. The information retrieved supports clinical judgment but does not itself modify prescriptions, dispense medications, or commit any action.
From the tool's definition Tool name is 'get_alternative' and description states 'Get the primary therapeutic alternative when a drug is unavailable.' The verb 'get' indicates retrieval of reference data (therapeutic alternatives from a formulary or drug database).
