Implementation Reference

• src/tools.ts:26-37 (handler)

  The handler function that executes the get-weather tool logic, generating a mock weather forecast for the given city.

  handler: async ({ city }: { city: string }) => {
      // Mock implementation
      const weather = ["Sunny", "Cloudy", "Rainy"][Math.floor(Math.random() * 3)];
      return {
          content: [
              {
                  type: "text" as const,
                  text: `The weather in ${city} is ${weather}`,
              },
          ],
      };
  },

• src/tools.ts:23-25 (schema)

  The Zod input schema defining the 'city' parameter for the get-weather tool.

  inputSchema: z.object({
      city: z.string().describe("The city name"),
  }),

• src/tools.ts:21-38 (registration)

  The get-weather tool is registered in the TOOLS object exported from tools.ts, which is used by the MCP server for listing and calling tools.

  "get-weather": {
      description: "Get weather forecast for a city",
      inputSchema: z.object({
          city: z.string().describe("The city name"),
      }),
      handler: async ({ city }: { city: string }) => {
          // Mock implementation
          const weather = ["Sunny", "Cloudy", "Rainy"][Math.floor(Math.random() * 3)];
          return {
              content: [
                  {
                      type: "text" as const,
                      text: `The weather in ${city} is ${weather}`,
                  },
              ],
          };
      },
