Implementation Reference

• src/index.ts:150-159 (handler)

  Handler function that executes the median tool logic by calling Statistics.median(numbers) and returning the result as text content.

  }, async ({ numbers }) => {
      const value = Statistics.median(numbers)
  
      return {
          content: [{
              type: "text",
              text: `${value}`
          }]
      }
  })

• src/index.ts:149-149 (schema)

  Input schema using Zod: requires an array of at least one number.

  numbers: z.array(z.number()).min(1).describe("Array of numbers to find the median of")

• src/index.ts:148-148 (registration)

  Registration of the 'median' tool on the mathServer with description, schema, and handler.

  mathServer.tool("median", "Calculates the median of a list of numbers", {

• src/Classes/Statistics.ts:21-38 (helper)

  Core implementation of median calculation: sorts the array, handles odd/even length to find middle value(s).

  static median(numbers: number[]) {
      //Sort numbers
      numbers.sort()
  
      //Find the median index
      const medianIndex = numbers.length / 2
  
      let medianValue: number;
      if (numbers.length % 2 !== 0) {
          //If number is odd
          medianValue = numbers[Math.floor(medianIndex)]
      } else {
          //If number is even
          medianValue = (numbers[medianIndex] + numbers[medianIndex - 1]) / 2
      }
  
      return medianValue
  }
