Implementation Reference

• src/mcp/tools.js:292-339 (handler)

  Core handler function for the 'list_huggingface_files' tool. Performs input validation, constructs options with 'standard' mode, calls downloader.list(), and formats the result.

  async callListTool(args) {
    try {
      // 基础验证
      if (!args.repo_id) {
        return CallToolResult.error(
          ToolContent.text('缺少必需参数: repo_id')
        );
      }
  
      logger.info(`列出文件: ${args.repo_id}`);
  
      // 构建选项 - 固定mode为standard
      const options = {
        revision: args.revision,
        pattern: args.pattern,
        exclude: args.exclude,
        maxFiles: args.max_files,
        maxDepth: args.max_depth,
        sort: args.sort,
        mode: 'standard', // 固定为标准模式
        token: args.token || process.env.HF_TOKEN
      };
  
      // 执行列表
      const result = await this.downloader.list(args.repo_id, options);
  
      if (result.success) {
        logger.info(`获取到 ${result.files?.length || 0} 个文件`);
        return CallToolResult.success(
          ToolContent.text(JSON.stringify(result, null, 2))
        );
      } else {
        logger.error('列表失败:', result.error);
        return CallToolResult.error(
          ToolContent.text(JSON.stringify({
            success: false,
            error: result.error,
            suggestions: result.suggestions
          }, null, 2))
        );
      }
    } catch (error) {
      logger.error('工具调用失败:', error);
      return CallToolResult.error(
        ToolContent.text(`工具调用失败: ${error.message}`)
      );
    }
  }

• src/mcp/tools.js:24-31 (registration)

  Registration of the list_huggingface_files tool within the getTools() method that returns all available tools.

  getTools() {
    return [
      this.getDownloadTool(),
      this.getListTool(),
      this.getExploreTool(),
      this.getSearchTool()
    ];
  }

• src/mcp/tools.js:446-461 (registration)

  Tool dispatch registration in the central callTool switch statement, routing 'list_huggingface_files' to callListTool.

  async callTool(name, args) {
    switch (name) {
    case 'download_huggingface_model':
      return await this.callDownloadTool(args);
    case 'list_huggingface_files':
      return await this.callListTool(args);
    case 'explore_huggingface_repo':
      return await this.callExploreTool(args);
    case 'search_huggingface_files':
      return await this.callSearchTool(args);
    default:
      return CallToolResult.error(
        ToolContent.text(`未知工具: ${name}`)
      );
    }
  }
