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.
