AI agents call get_drug_gene_interactions to retrieve information from Pgx without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves drug-gene interaction data from pharmacogenomics databases (ClinVar, PharmGKB, gnomAD). The 'get_' prefix and server context indicate a read-only query with no side effects. The blast radius is low—misuse would only return incorrect or irrelevant interaction data, not modify systems or cause financial harm.
From the tool's definition Tool name 'get_drug_gene_interactions' indicates a retrieval operation. Sibling tools on the server (get_dosing_guideline, get_drug_info, get_trial_details, get_variant_frequency, lookup_variant_clinvar, search_clinical_trials, search_drug_targets,…
