Implementation Reference

• src/index.ts:84-91 (handler)

  The handler function for the 'square' tool that computes the square of the input number 'a' and returns a text response with the result.

  async ({ a }) => {
    const result = a * a;
    return {
      content: [
        { type: "text", text: `The square of ${a} is ${result}` }
      ]
    };
  }

• src/index.ts:82-82 (schema)

  Input schema for the 'square' tool, defining the parameter 'a' as a number using Zod validation.

  inputSchema: { a: z.number() },

• src/index.ts:77-92 (registration)

  Registration of the 'square' tool on the MCP server, including schema and handler function.

  server.registerTool(
    "square",
    {
      title: "Square tool",
      description: "Calculate the square of a number",
      inputSchema: { a: z.number() },
    },
    async ({ a }) => {
      const result = a * a;
      return {
        content: [
          { type: "text", text: `The square of ${a} is ${result}` }
        ]
      };
    }
  );
