Implementation Reference

• src/index.ts:252-260 (handler)

  The handler function that executes the 'round' tool logic by calling Arithmetic.round on the input number and returning the result as MCP text content.

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

• src/index.ts:251-251 (schema)

  The Zod input schema defining a single 'number' parameter for the 'round' tool.

  number: z.number().describe("The number to round"),

• src/index.ts:246-260 (registration)

  The registration of the 'round' tool on the MCP server, including JSDoc, name, description, schema, and handler.

  /**
   * Round operation
   * Rounds a number to the nearest integer
   */
  mathServer.tool("round", "Rounds a number to the nearest integer", {
      number: z.number().describe("The number to round"),
  }, async ({ number }) => {
      const value = Arithmetic.round(number)
      return {
          content: [{
              type: "text",
              text: `${value}`
          }]
      }
  })

• src/Classes/Arithmetic.ts:77-85 (helper)

  The helper static method 'Arithmetic.round' that performs the core rounding logic using Math.round.

  /**
   * Calculate the round of a number
   * @param number - Number to find the round of
   * @returns round of the number
   */
  static round(number: number) {
      const round = Math.round(number)
      return round
  }
