Implementation Reference
- src/tools/analytics/getTopPages.ts:10-67 (handler)Main handler function implementing the get_top_pages tool logic. Fetches GA4 report data for top pages by page views, processes dimensions and metrics, formats results into TopPage objects ranked by page views.export async function getTopPages( input: GetTopPagesInput ): Promise<GetTopPagesOutput> { const propertyId = getPropertyId(input.propertyId); const property = formatPropertyPath(propertyId); const dateRange = periodToDateRange(input.period); const limit = input.limit || 10; const response = await executeReport({ property, dateRanges: [dateRange], dimensions: [{ name: "pagePath" }, { name: "pageTitle" }], metrics: [ { name: "screenPageViews" }, { name: "totalUsers" }, { name: "averageSessionDuration" }, { name: "bounceRate" }, ], orderBys: [{ metric: { metricName: "screenPageViews" }, desc: true }], limit, ...(input.pathFilter && { dimensionFilter: { filter: { fieldName: "pagePath", stringFilter: { matchType: "BEGINS_WITH", value: input.pathFilter, }, }, }, }), }); const pages: TopPage[] = []; let rank = 1; for (const row of response.rows || []) { const dimensionValues = row.dimensionValues || []; const metricValues = row.metricValues || []; const getValue = (index: number): number => { const value = metricValues[index]?.value; return value ? parseFloat(value) : 0; }; pages.push({ rank: rank++, pagePath: dimensionValues[0]?.value || "", pageTitle: dimensionValues[1]?.value || "(タイトルなし)", pageViews: Math.round(getValue(0)), uniquePageViews: Math.round(getValue(1)), avgTimeOnPage: formatDuration(getValue(2)), bounceRate: formatPercentageFromDecimal(getValue(3)), }); } return { pages }; }
- src/types.ts:131-149 (schema)TypeScript interfaces defining input (GetTopPagesInput), output (GetTopPagesOutput), and data structure (TopPage) for the get_top_pages tool.export interface GetTopPagesInput extends PropertyId { period: ShortPeriod; limit?: number; pathFilter?: string; } export interface TopPage { rank: number; pagePath: string; pageTitle: string; pageViews: number; uniquePageViews: number; avgTimeOnPage: string; bounceRate: string; } export interface GetTopPagesOutput { pages: TopPage[]; }
- src/server.ts:221-246 (registration)MCP tool registration in the tools array, defining name, description, and inputSchema for get_top_pages.{ name: "get_top_pages", description: "人気ページのランキングを取得します。PV数、滞在時間、直帰率などを確認できます。", inputSchema: { type: "object" as const, properties: { propertyId: { type: "string", description: "GA4プロパティID" }, period: { type: "string", enum: ["today", "yesterday", "7days", "28days", "30days"], description: "集計期間", }, limit: { type: "number", description: "取得件数（デフォルト: 10）", }, pathFilter: { type: "string", description: 'パスのフィルター（例: "/blog" で /blog 配下のみを取得）', }, }, required: ["period"], }, },
- src/server.ts:632-643 (registration)Dispatch handler in switch statement that calls the getTopPages function with parsed arguments.case "get_top_pages": return await getTopPages({ propertyId: args.propertyId as string | undefined, period: args.period as | "today" | "yesterday" | "7days" | "28days" | "30days", limit: args.limit as number | undefined, pathFilter: args.pathFilter as string | undefined, });
- src/tools/analytics/index.ts:2-2 (helper)Re-export of the getTopPages handler from its implementation file for convenient import in server.ts.export { getTopPages } from "./getTopPages.js";
