Implementation Reference
- The main handler function for the 'generate-typescript-types' tool. It creates a TypeScriptTypesGenerator instance, calls its generate method with parameters, and formats the result as MCP content.async execute(params: z.infer<typeof this.schema>) { let progress = 0; let progressMessage = ''; // 定义进度回调 const progressCallback = (newProgress: number, message: string) => { progress = newProgress; progressMessage = message; console.log(`[Progress] ${Math.round(newProgress * 100)}%: ${message}`); }; try { console.log(`[TypeScriptTypesGeneratorTool] 开始生成TypeScript类型: ${params.swaggerUrl}`); console.log(`[TypeScriptTypesGeneratorTool] 缓存: ${params.useCache ? '启用' : '禁用'}, 懒加载: ${params.lazyLoading ? '启用' : '禁用'}`); // 创建生成器实例 const generator = new TypeScriptTypesGenerator(); // 执行生成 const result = await generator.generate({ ...params, progressCallback } as TypeScriptTypesGeneratorOptions); // 处理结果 if (result.success) { console.log(`[TypeScriptTypesGeneratorTool] 类型生成成功，生成了 ${result.files.length} 个文件`); return { content: [ { type: 'text' as const, text: JSON.stringify({ success: true, files: result.files, warnings: result.warnings, progress: 1.0, progressMessage: '完成' }, null, 2) } ] }; } else { console.error(`[TypeScriptTypesGeneratorTool] 类型生成失败: ${result.error}`); return { content: [ { type: 'text' as const, text: JSON.stringify({ success: false, error: result.error, progress: progress, progressMessage: progressMessage }, null, 2) } ] }; } } catch (error) { console.error(`[TypeScriptTypesGeneratorTool] 执行异常:`, error); // 返回错误结果 return { content: [ { type: 'text' as const, text: JSON.stringify({ success: false, error: error instanceof Error ? error.message : String(error), progress: progress, progressMessage: progressMessage }, null, 2) } ] }; } }
- Input schema using Zod for validating tool parameters including swaggerUrl, output options, filtering, caching, etc.schema = z.object({ /** * Swagger/OpenAPI document URL */ swaggerUrl: z.string().describe('Swagger/OpenAPI document URL'), /** * Output directory */ outputDir: z.string().optional().describe('Output directory'), /** * Whether to overwrite existing files */ overwrite: z.boolean().optional().describe('Whether to overwrite existing files'), /** * File prefix */ filePrefix: z.string().optional().describe('File prefix'), /** * File suffix */ fileSuffix: z.string().optional().describe('File suffix'), /** * Whether to use namespace */ useNamespace: z.boolean().optional().describe('Whether to use namespace for wrapping types'), /** * Namespace name */ namespace: z.string().optional().describe('Namespace name'), /** * Whether to generate enums */ generateEnums: z.boolean().optional().describe('Whether to generate enum types'), /** * Whether to use strict types */ strictTypes: z.boolean().optional().describe('Whether to use strict types'), /** * Excluded schema names */ excludeSchemas: z.array(z.string()).optional().describe('Array of schema names to exclude'), /** * Included schema names */ includeSchemas: z.array(z.string()).optional().describe('Array of schema names to include'), /** * Whether to generate index file */ generateIndex: z.boolean().optional().describe('Whether to generate an index file'), /** * Request headers */ headers: z.record(z.string()).optional().describe('Request headers'), /** * Whether to use cache */ useCache: z.boolean().optional().describe('Whether to use cache'), /** * Cache TTL in minutes */ cacheTTLMinutes: z.number().optional().describe('Cache TTL in minutes'), /** * Whether to skip validation */ skipValidation: z.boolean().optional().describe('Whether to skip validation'), /** * Whether to use lazy loading */ lazyLoading: z.boolean().optional().describe('Whether to use lazy loading') });
