Implementation Reference
- src/index.ts:425-464 (handler)The main handler function that executes the tool logic. It queries the Supabase database for counts of premiums, insurers, and locations; determines available years by checking counts per year; computes unique insurers from premiums; and formats statistics into a markdown-like string response.
async function getDatabaseStats(): Promise<string> { const db = getSupabase(); // Hole Statistiken const [premiumsCount, insurersCount, locationsCount] = await Promise.all([ db.from("premiums").select("*", { count: "exact", head: true }), db.from("insurers").select("*", { count: "exact", head: true }), db.from("locations").select("*", { count: "exact", head: true }) ]); // Prüfe welche Jahre Daten haben (effizienter als alle Zeilen zu holen) const yearsToCheck = [2016, 2017, 2018, 2019, 2020, 2021, 2022, 2023, 2024, 2025, 2026]; const yearChecks = await Promise.all( yearsToCheck.map(year => db.from("premiums").select("year", { count: "exact", head: true }).eq("year", year) ) ); const availableYears = yearsToCheck.filter((year, index) => yearChecks[index].count && yearChecks[index].count > 0 ); // Hole Anzahl unique Versicherer aus premiums (statt insurers-Tabelle) const { data: insurerSample } = await db .from("premiums") .select("insurer_id") .limit(10000); const uniqueInsurers = new Set(insurerSample?.map(p => p.insurer_id) || []); let result = `📊 Datenbank-Statistiken\n\n`; result += `📋 Tabellen:\n`; result += ` • premiums: ${premiumsCount.count?.toLocaleString("de-CH")} Einträge\n`; result += ` • insurers: ${uniqueInsurers.size} aktive Versicherer\n`; result += ` • locations: ${locationsCount.count?.toLocaleString("de-CH")} PLZ-Einträge\n\n`; result += `📅 Verfügbare Jahre: ${availableYears.join(", ")}\n\n`; result += `🔗 Datenquelle: BAG Priminfo (priminfo.admin.ch)\n`; return result; } - src/index.ts:193-197 (schema)The input schema definition for the tool, specifying no required parameters (empty object).
