Implementation Reference

• src/index.ts:19-30 (handler)

  The asynchronous handler function for the 'hello-world' tool that receives a 'name' parameter and returns a text content block with a greeting message.

  async ({ name }) => {
    const response = `Hello ${name}`;
  
    return {
      content: [
        {
          type: "text",
          text: response,
        },
      ],
    };
  }

• src/index.ts:16-18 (schema)

  The input schema for the 'hello-world' tool, defining a required 'name' string parameter.

  {
    name: z.string().describe("The name of the user"),
  },

• src/index.ts:14-31 (registration)

  The registration of the 'hello-world' tool on the MCP server using server.tool(), specifying the tool name, description, input schema, and handler function.

    "hello-world",
    "Say hello to the user",
    {
      name: z.string().describe("The name of the user"),
    },
    async ({ name }) => {
      const response = `Hello ${name}`;
  
      return {
        content: [
          {
            type: "text",
            text: response,
          },
        ],
      };
    }
  );
