Implementation Reference
- src/index.ts:52-72 (handler)Handler for the 'add' tool: validates arguments using Zod and returns the sum as text content.
if (name === "add") { // zod でパラメータをバリデーション const argsSchema = z.object({ a: z.number(), b: z.number(), }); const { a, b } = argsSchema.parse(args); // 足し算を実行 const result = a + b; return { content: [ { type: "text", text: `${a} + ${b} = ${result}`, }, ], }; } - src/index.ts:29-42 (schema)Input schema definition for the 'add' tool, declared in the list tools response.
inputSchema: { type: "object", properties: { a: { type: "number", description: "The first number", }, b: { type: "number", description: "The second number", }, }, required: ["a", "b"], }, - src/index.ts:23-46 (registration)Registration of the ListToolsRequestHandler which lists the 'add' tool with its schema.
