Implementation Reference

• src/tools/sqrt.ts:6-17 (handler)

  Full implementation of the 'sqrt' tool, including schema definition and the handler function that computes Math.sqrt(a).
  export const sqrt: Tool = { schema: { name: "sqrt", description: "Square root of a number", inputSchema: zodToJsonSchema(z.object({ a: z.number() })), }, handle: async (params) => { const a = params.a as number; const result = Math.sqrt(a); return { content: [{ type: "text", text: `The square root of ${a} is ${result}` }] }; }, };
• src/tools/sqrt.ts:7-11 (schema)

  Input schema for the sqrt tool using Zod for validation (expects object with 'a' number).
  schema: { name: "sqrt", description: "Square root of a number", inputSchema: zodToJsonSchema(z.object({ a: z.number() })), },
• src/server.ts:7-9 (registration)

  The 'sqrt' tool is imported and registered in the main tools array used by the MCP server.
  import { add, div, mod, mul, sqrt, sub } from "./tools"; const tools = [add, div, mod, mul, sqrt, sub];
• src/tools/index.ts:5-5 (registration)

  Re-export of the sqrt tool from the tools index module.
  export * from "./sqrt";
