Implementation Reference
- src/minio-client.ts:130-139 (handler)Core handler function that performs the file download from MinIO bucket to local path using fGetObject.
async downloadFile(bucketName: string, objectName: string, filePath: string): Promise<void> { this.ensureConnected(); const dir = path.dirname(filePath); if (!fs.existsSync(dir)) { fs.mkdirSync(dir, { recursive: true }); } await this.client!.fGetObject(bucketName, objectName, filePath); } - src/index.ts:149-161 (registration)Tool registration in ListToolsRequestHandler, defining name, description, and input schema.
{ name: 'download_file', description: '从存储桶下载文件', inputSchema: { type: 'object', properties: { bucketName: { type: 'string', description: '存储桶名称' }, objectName: { type: 'string', description: '对象名称' }, filePath: { type: 'string', description: '本地保存路径' } }, required: ['bucketName', 'objectName', 'filePath'] } }, - src/index.ts:435-439 (schema)Zod schema validation for download_file tool arguments in the CallTool handler.
const { bucketName, objectName, filePath } = z.object({ bucketName: z.string(), objectName: z.string(), filePath: z.string() }).parse(args); - src/index.ts:434-450 (handler)Dispatch handler in CallToolRequestHandler that invokes the MinIO client's downloadFile method and formats response.
case 'download_file': { const { bucketName, objectName, filePath } = z.object({ bucketName: z.string(), objectName: z.string(), filePath: z.string() }).parse(args); await this.minioClient.downloadFile(bucketName, objectName, filePath); return { content: [ { type: 'text', text: `成功下载文件 ${bucketName}/${objectName} 到 ${filePath}` } ] }; }
