āš™ļø Claude Desktop Configuration

For Windows Users with WSL

  1. Locate your Claude Desktop configuration file:
File -> Settings -> Edit Config
  1. Add the WebScrappingServer configuration
{
  "mcpServers": {
    "WebScrapingServer": {
      "command": "wsl",
      "args": [
        "-d",
        "Ubuntu",
        "bash",
        "-lc",
        "cd ~/path/to/mcp-webscraper && uv run --with mcp[cli] mcp run scrapping.py"
      ]
    }
  }
}

Important: Replace ~/path/to/mcp-webscraper with the actual path to your project folder in WSL. To find your WSL path:

pwd

3. Restart Claude Desktop

  1. Completely quit Claude Desktop (not just close the window)
  2. Start Claude Desktop again
  3. Look for the šŸ”Œ icon in the text input area

Advanced SEO analysis
Please help me to crawl my personal blog https://yourblog.com with a limit of 150 pages.
I would like to understand how articles are referring to each other.
Can you help me to perform this type of analysis?
