Portable Web Scraper

A drop-in MCP (Model Context Protocol) server for efficient web scraping with two-step workflow optimization.

✨ Features

• Two-Step Workflow: Get HTML structure preview first, then scrape with targeted filters
• Token Efficient: Minimal token usage for AI analysis and decision-making
• Clean Output: Automatically removes navigation, ads, and UI elements
• Portable: Drop anywhere and add to your MCP servers
• Multiple Tools: Single page, multi-page, and documentation site scraping

🚀 Quick Start

Option 1: Automated Installation

python install.py

Option 2: Manual Setup

1. Install dependencies:

   pip install -r requirements.txt
   

2. Copy to your MCP servers directory:

   cp portable_mcp_scraper.py /path/to/your/mcp/servers/
   

3. Add to your MCP configuration (e.g., ~/.cursor/mcp.json):

   {
     "mcpServers": {
       "web-scraper": {
         "command": "python",
         "args": ["/path/to/your/mcp/servers/portable_mcp_scraper.py"]
       }
     }
   }
   

4. Restart your MCP client

2. Step 2: Scrape with AI-determined filters (clean, focused content)

Efficiency Gains:

• For 100-page documentation: ~90% token reduction
• AI only analyzes structure, not full content
• Clean, focused output without manual filtering
• Massive cost savings for large documentation sites

🧪 Testing

Run the test script to verify everything works:

python test_mcp_server.py

📋 Example Usage

Basic Single Page Scraping

# Get structure preview first
preview = preview_html_structure("https://cursor.com/docs")

# Then scrape with filters
content = scrape_web_content(
    url="https://cursor.com/docs",
    include_tags=["h1", "h2", "h3", "p", "div"],
    exclude_tags=["nav", "footer", "aside"],
    save_to_file=True
)

Documentation Site Scraping

# Scrape entire documentation site
summary = scrape_documentation_site(
    base_url="https://cursor.com/docs",
    max_pages=20,
    save_to_files=True,
    output_dir="./cursor_docs"
)
