MCP工具

1. extract_logo - 提取网站Logo

从指定网站URL提取Logo图标。

参数:

url (必需): 要提取Logo的网站URL
optimize (可选): 是否对Logo进行AI优化处理，默认为true
format (可选): 输出格式选择 ('png', 'svg', 'both')，默认为'both'
size (可选): 输出图片尺寸（像素），默认为256

示例:

{
  "name": "extract_logo",
  "arguments": {
    "url": "https://www.google.com",
    "optimize": true,
    "format": "both",
    "size": 256
  }
}

返回结果:

{
  "url": "https://www.google.com",
  "logoUrl": "https://www.google.com/favicon.ico",
  "type": "favicon",
  "source": "HTML link标签",
  "originalSize": {"width": 32, "height": 32},
  "originalFormat": "ico",
  "files": [
    {
      "format": "png",
      "size": 256,
      "data": "base64编码的图片数据",
      "optimized": true
    },
    {
      "format": "svg",
      "data": "SVG内容",
      "optimized": true
    }
  ]
}

2. analyze_logo_candidates - 分析Logo候选项

分析网站的所有Logo候选项并返回详细信息。

参数:

url (必需): 要分析的网站URL

示例:

{
  "name": "analyze_logo_candidates",
  "arguments": {
    "url": "https://www.apple.com"
  }
}

返回结果:

{
  "url": "https://www.apple.com",
  "totalCandidates": 5,
  "candidates": [
    {
      "index": 1,
      "url": "https://www.apple.com/favicon.ico",
      "type": "favicon",
      "source": "HTML link标签",
      "score": 85,
      "attributes": {"sizes": "32x32", "type": "image/x-icon"}
    }
  ],
  "recommended": {
    "url": "https://www.apple.com/apple-touch-icon.png",
    "type": "apple-touch-icon",
    "source": "Apple Touch Icon",
    "score": 95
  }
}

评分系统

系统使用智能评分算法来选择最佳Logo：

Favicon评分 (基础分60)

尺寸加分: ≥128px (+30), ≥64px (+20), ≥32px (+10)
格式加分: SVG (+20), PNG (+15)

Apple Touch Icon评分 (基础分80)

尺寸加分: ≥180px (+20), ≥120px (+15), ≥76px (+10)

Logo图像评分 (基础分50)

Alt属性: 包含"logo" (+25), "brand" (+15), "company" (+10)
Class属性: 包含"logo" (+20), "brand" (+15)
路径: 包含"logo" (+15), "brand" (+10), SVG格式 (+10)
