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.
