Implementation Reference
- src/index.ts:209-259 (handler)The core handler function for the get-drug-adverse-events tool. Builds an OpenFDA API query for adverse events using the drug name, optional limit and seriousness filters. Fetches data, handles errors/no results, maps results to a user-friendly format (report ID, seriousness, patient details, reactions, etc.), and returns formatted JSON text.
async ({ drugName, limit, seriousness }) => { let searchQuery = `patient.drug.medicinalproduct:"${drugName}"`; if (seriousness !== "all") { const serious = seriousness === "serious" ? "1" : "2"; searchQuery += `+AND+serious:${serious}`; } const url = new OpenFDABuilder() .context("event") .search(searchQuery) .limit(limit) .build(); const { data: eventData, error } = await makeOpenFDARequest<any>(url); if (error) { return { content: [{ type: "text", text: `Failed to retrieve adverse events for "${drugName}": ${error.message}`, }], }; } if (!eventData || !eventData.results || eventData.results.length === 0) { return { content: [{ type: "text", text: `No adverse events found for "${drugName}".`, }], }; } const events = eventData.results.map((event: any) => ({ report_id: event.safetyreportid, serious: event.serious === "1" ?
