Implementation Reference

• src/index.ts:835-866 (handler)

  The implementation of the get_alerts tool handler.

  private handleGetAlerts(args: {
    severity?: string;
    acknowledged?: boolean;
    deviceId?: string;
  }) {
    let alerts = [...mockAlerts];
  
    if (args.deviceId) {
      alerts = alerts.filter((a) => a.deviceId === args.deviceId);
    }
    if (args.severity) {
      alerts = alerts.filter((a) => a.severity === args.severity);
    }
    if (args.acknowledged !== undefined) {
      alerts = alerts.filter((a) => a.acknowledged === args.acknowledged);
    }
  
    // Sort by timestamp descending
    alerts.sort(
      (a, b) =>
        new Date(b.timestamp).getTime() - new Date(a.timestamp).getTime()
    );
  
    return {
      content: [
        {
          type: "text",
          text: JSON.stringify(alerts, null, 2),
        },
