Instructions

Implementation Reference

• src/index.ts:212-227 (registration)

  Registration of the "floor" MCP tool, including JSDoc description, input schema (number: z.number()), and inline handler function that calls Arithmetic.floor and returns the floored value as text content.

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

• src/Classes/Arithmetic.ts:57-65 (helper)

  Static helper method in Arithmetic class that implements the floor operation by calling JavaScript's Math.floor(number). This is invoked by the floor tool's handler.

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