  case "get_transport_options": {
    const validatedArgs = GetTransportOptionsSchema.parse(args);
    return {
      content: [
        {
          type: "text",
          text: `Transport options from ${validatedArgs.origin} to ${validatedArgs.destination}\n` +
                `Date: ${validatedArgs.date}`,
        },
      ],
    };
  }

    destination: z.string().describe("Destination point"),
    date: z.string().describe("Travel date (YYYY-MM-DD)"),
  });
