AI agents call openemr_fda_adverse_events to retrieve information from Openemr without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves public FDA adverse event data without side effects. It does not create, modify, delete, or execute operations. The blast radius of misuse is minimal—an agent could spam queries or retrieve information, but cannot alter medical records, trigger financial transactions, or cause irreversible harm.
From the tool's definition Tool description states 'Query FDA FAERS database for adverse event reports on a drug' — a read-only query operation with no modification, deletion, or execution of external commands.
