Implementation Reference

• src/index.ts:186-197 (handler)

  Handler function for the 'power' tool. Extracts base and exponent from arguments, computes Math.pow(base, exponent), and returns the result as formatted text content.

  case "power": {
    const { base, exponent } = args as { base: number; exponent: number };
    const result = Math.pow(base, exponent);
    return {
      content: [
        {
          type: "text",
          text: `${base}^${exponent} = ${result}`,
        },
      ],
    };
  }

• src/index.ts:93-106 (schema)

  Input schema for the 'power' tool, defining 'base' and 'exponent' as required number properties.

  inputSchema: {
    type: "object",
    properties: {
      base: {
        type: "number",
        description: "底数",
      },
      exponent: {
        type: "number",
        description: "指数",
      },
    },
    required: ["base", "exponent"],
  },

• src/index.ts:90-107 (registration)

  Registration of the 'power' tool in the tools array, including name, description, and input schema. This array is returned by the ListToolsRequest handler.

  {
    name: "power",
    description: "计算一个数字的幂",
    inputSchema: {
      type: "object",
      properties: {
        base: {
          type: "number",
          description: "底数",
        },
        exponent: {
          type: "number",
          description: "指数",
        },
      },
      required: ["base", "exponent"],
    },
  },
