Math-MCP

Instructions

Implementation Reference

• src/index.ts:62-74 (registration)

  Registration of the 'multiply' MCP tool, including schema definition and inline handler function that delegates to Arithmetic.multiply and formats the response.

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

• src/index.ts:65-74 (handler)

  The handler function executed when the 'multiply' tool is called. It performs the multiplication via helper and returns a standardized MCP response.

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

• src/index.ts:63-64 (schema)

  Zod-based input schema for the 'multiply' tool parameters.

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

• src/Classes/Arithmetic.ts:30-33 (helper)

  Arithmetic helper static method implementing the multiplication logic called by the tool handler.

  static multiply(firstNumber: number, secondNumber: number) {
      const product = firstNumber * secondNumber
      return product
  }
