  case 'list_ocr_languages': {
    // 获取支持的语言列表
    const languages = getSupportedLanguages();
    
    // 格式化为 Markdown 列表
    const languageList = languages
      .map((lang) => `- \`${lang.code}\`: ${lang.name}`)
      .join('\n');
  
    return {
      content: [
        {
          type: 'text',
          text: `## 支持的 OCR 语言\n\n${languageList}\n\n使用时将语言代码传入 \`languages\` 参数数组中，例如：\`["chi_sim", "eng"]\``,
        },
      ],
    };
  }
