Implementation Reference

• src/index.ts:754-778 (handler)

  The handleGetSensors method implements the logic for the get_sensors tool by filtering mockSensors based on optional arguments (type, status, equipmentId) and returning the result as a text content object.

  private handleGetSensors(args: {
    type?: string;
    status?: string;
    equipmentId?: string;
  }) {
    let sensors = [...mockSensors];
  
    if (args.equipmentId) {
      sensors = sensors.filter((s) => s.equipmentId === args.equipmentId);
    }
    if (args.type) {
      sensors = sensors.filter((s) => s.type === args.type);
    }
    if (args.status) {
      sensors = sensors.filter((s) => s.status === args.status);
    }
  
    return {
      content: [
        {
          type: "text",
          text: JSON.stringify(sensors, null, 2),
        },
      ],
    };
