Implementation Reference
- src/services/ci/ai.service.ts:154-192 (handler)Core implementation of the aiQrcode tool handler in the CIAIService class. Performs QR code recognition by sending a GET request to Tencent COS with ci-process: QRcode query parameter.
async aiQrcode(objectKey: string) { try { const result = await new Promise((resolve, reject) => { this.cos.request( { Bucket: this.bucket, // 存储桶，必须字段 Region: this.region, // 存储桶所在地域，必须字段 如 ap-beijing Method: 'GET', Key: objectKey, // Url: url, Query: { 'ci-process': 'QRcode', // 数据万象处理能力，二维码识别固定为 QRcode, cover: 0, }, }, function (error, data) { if (error) { // 处理请求失败 reject(error); } else { // 处理请求成功 resolve(data); } }, ); }); return { isSuccess: true, message: '二维码识别成功', data: result, }; } catch (error) { return { isSuccess: false, message: '二维码识别失败', data: error, }; } } - src/server.ts:401-421 (registration)Registration of the 'aiQrcode' MCP tool, including name, description, Zod input schema for objectKey, and wrapper handler that calls the service method and formats the response.
server.tool( 'aiQrcode', '图片处理-二维码识别-识别存储桶内二维码图片内容', { objectKey: z .string() .describe('COS对象键（完整路径）示例: images/qrcode.jpg'), }, async ({ objectKey }) => { const res = await CIAIInstance.aiQrcode(objectKey); return { content: [ { type: 'text', text: JSON.stringify(res.data, null, 2), }, ], isError: !res.isSuccess, }; }, ); - src/server.ts:404-408 (schema)Zod schema definition for the aiQrcode tool input parameter 'objectKey'.
{ objectKey: z .string() .describe('COS对象键（完整路径）示例: images/qrcode.jpg'), }, - src/server.ts:44-44 (helper)Instantiation of the CIAIService instance used by the aiQrcode tool.
const CIAIInstance = new CIAIService(bucket, region, cos);
