Implementation Reference

• src/services/ci/pic.service.ts:22-44 (handler)

  The core handler function in CIPicService that performs the COS 'imageInfo' request to retrieve image information.

  async imageInfo(objectKey: string) {
    try {
      const result = await this.cos.request({
        Bucket: this.bucket,
        Region: this.region,
        Method: 'GET',
        Key: objectKey,
        Action: 'imageInfo',
        RawBody: false,
      });
      return {
        isSuccess: true,
        message: '获取图片信息成功',
        data: result,
      };
    } catch (error) {
      return {
        isSuccess: false,
        message: '获取图片信息失败',
        data: error,
      };
    }
  }

• src/server.ts:319-337 (registration)

  MCP tool registration for 'imageInfo', defining name, description, input schema, and handler wrapper that calls the service method.

  server.tool(
    'imageInfo',
    '图片处理-获取图片信息',
    {
      objectKey: z.string().describe('图片在存储桶里的路径'),
    },
    async ({ objectKey }) => {
      const res = await CIPicInstance.imageInfo(objectKey);
      return {
        content: [
          {
            type: 'text',
            text: JSON.stringify(res.data, null, 2),
          },
        ],
        isError: !res.isSuccess,
      };
    },
  );

• src/server.ts:322-324 (schema)

  Input schema validation using Zod for the 'objectKey' parameter.

  {
    objectKey: z.string().describe('图片在存储桶里的路径'),
  },
