Implementation Reference
- src/index.ts:960-978 (handler)Executes the get_recent_cost tool by calling AWS CostExplorer GetCostAndUsageCommand for daily UnblendedCost over the specified date range (defaults to last 7 days), maps the results to time periods and totals, and returns formatted JSON.
if (name === "get_recent_cost") { const endDate = (args as any)?.end_date || new Date().toISOString().split('T')[0]; const startDate = (args as any)?.start_date || new Date(Date.now() - 7 * 24 * 60 * 60 * 1000).toISOString().split('T')[0]; const command = new GetCostAndUsageCommand({ TimePeriod: { Start: startDate, End: endDate }, Granularity: "DAILY", Metrics: ["UnblendedCost"] }); const response = await costExplorerClient.send(command); const costs = response.ResultsByTime?.map(r => ({ TimePeriod: r.TimePeriod, Total: r.Total?.UnblendedCost })) || []; return { content: [{ type: "text", text: JSON.stringify(costs, null, 2) }] }; - src/index.ts:175-190 (schema)Input schema and tool definition registered in ListTools handler, specifying optional start_date and end_date parameters in YYYY-MM-DD format.
