Implementation Reference

• src/index.ts:26-38 (registration)

  Registration of the 'add' tool including description, input schema using Zod, and the handler function that delegates to Arithmetic.add and formats the response.

  mathServer.tool("add", "Adds two numbers together", {
      firstNumber: z.number().describe("The first addend"),
      secondNumber: z.number().describe("The second addend")
  }, async ({ firstNumber, secondNumber }) => {
      const value = Arithmetic.add(firstNumber, secondNumber)
  
      return {
          content: [{
              type: "text",
              text: `${value}`
          }]
      }
  })

• src/index.ts:29-38 (handler)

  The handler function for the 'add' tool, which performs the addition via Arithmetic.add and returns a text response.

  }, async ({ firstNumber, secondNumber }) => {
      const value = Arithmetic.add(firstNumber, secondNumber)
  
      return {
          content: [{
              type: "text",
              text: `${value}`
          }]
      }
  })

• src/index.ts:27-28 (schema)

  Zod schema defining the input parameters for the 'add' tool: two numbers.

  firstNumber: z.number().describe("The first addend"),
  secondNumber: z.number().describe("The second addend")

• src/Classes/Arithmetic.ts:8-11 (helper)

  Arithmetic.add static method implementing the core addition logic.

  static add(firstNumber: number, secondNumber: number): number {
      const sum = firstNumber + secondNumber;
      return sum
  }
