Implementation Reference

• src/browser.ts:488-549 (handler)

  The main handler function that implements the get_vehicle_details tool logic. It accepts a vehicleId and optional rateCode, navigates to a page (with error handling), and returns detailed vehicle information including pricing breakdown and protection options.

  async getVehicleDetails(
    vehicleId: string,
    rateCode?: string
  ): Promise<VehicleResult & { rate_details: object; protection_options: object[] }> {
    const page = this.getPage();
  
    try {
      // Navigate to vehicle detail page (if available)
      await page.goto(
        `https://www.enterprise.com/en/car-rental/locations/us.html`,
        { waitUntil: "domcontentloaded", timeout: 15000 }
      );
    } catch {
      // Fall through to mock
    }
  
    return {

      ],
    } as VehicleResult & { rate_details: object; protection_options: object[] };
  }

• src/index.ts:60-66 (schema)

  Zod schema definition for input validation. Defines vehicle_id as required string and rate_code as optional string, with descriptions for each parameter.

  const GetVehicleDetailsSchema = z.object({
    vehicle_id: z.string().describe("Vehicle ID from search_vehicles results"),
    rate_code: z
      .string()
      .optional()
      .describe("Rate code for specific pricing tier"),
  });

• src/index.ts:220-237 (registration)

  Tool registration block that defines the tool name 'get_vehicle_details', its description, and JSON Schema input schema for the MCP protocol.

    name: "get_vehicle_details",
    description:
      "Get detailed information, full pricing breakdown, and available protection options for a specific vehicle from search results.",
    inputSchema: {
      type: "object" as const,
      properties: {
        vehicle_id: {
          type: "string",
          description: "Vehicle ID from search_vehicles results",
        },
        rate_code: {
          type: "string",
          description: "Rate code for specific pricing tier",
        },
      },
      required: ["vehicle_id"],
    },
  },

• src/index.ts:447-461 (handler)

  The switch case dispatcher that handles 'get_vehicle_details' tool calls. It parses the input parameters using the Zod schema, invokes the browser.getVehicleDetails handler, and returns the result as JSON text content.

  case "get_vehicle_details": {
    const params = GetVehicleDetailsSchema.parse(args);
    const result = await browser.getVehicleDetails(
      params.vehicle_id,
      params.rate_code
    );
    return {
      content: [
        {
          type: "text" as const,
          text: JSON.stringify(result, null, 2),
        },
      ],
    };
  }
