🛠️ Quick Start

1. Installation

# Clone the repository git clone <repository-url> cd documentation-scraper # Install dependencies pip install -r requirements.txt

2. Configure Your Target

Edit config.py to set your documentation site:

SCRAPER_CONFIG = { "base_url": "https://docs.example.com/", # Your documentation site "output_dir": "docs_db", "max_pages": 200, # ... other settings }

3. Run the Scraper

python docs_scraper.py

4. Query Your Documentation

# Search for content python query_docs.py --search "tutorial" # Browse by section python query_docs.py --section "getting-started" # Get statistics python query_docs.py --stats

5. Set Up Claude Integration

# Generate MCP configuration files python utils/gen_mcp.py # Follow the instructions to add to Claude Desktop

⚙️ Configuration

Main Configuration (config.py)

The entire system is controlled by a single configuration file:

# Basic scraping settings SCRAPER_CONFIG = { "base_url": "https://docs.example.com/", "output_dir": "docs_db", "max_depth": 3, "max_pages": 200, "delay_between_requests": 0.5, } # URL filtering rules URL_FILTER_CONFIG = { "skip_patterns": [r'/api/', r'\.pdf$'], "allowed_domains": ["docs.example.com"], } # MCP server settings MCP_CONFIG = { "server_name": "docs-server", "default_search_limit": 10, "max_search_limit": 50, }

Environment Overrides

You can override any setting with environment variables:

export DOCS_DB_PATH="/custom/path/documentation.db" export DOCS_BASE_URL="https://different-docs.com/" python mcp_docs_server.py

🤖 Claude Desktop Integration

Automatic Setup

  1. Generate configuration files:

    python utils/gen_mcp.py

  2. Copy the generated config to Claude Desktop:

    • Windows: %APPDATA%\Claude\claude_desktop_config.json

    • macOS: ~/Library/Application Support/Claude/claude_desktop_config.json

  3. Restart Claude Desktop

Manual Setup

If you prefer manual setup, add this to your Claude Desktop config:

{ "mcpServers": { "docs": { "command": "python", "args": ["path/to/mcp_docs_server.py"], "cwd": "path/to/project", "env": { "DOCS_DB_PATH": "path/to/docs_db/documentation.db" } } } }

Available MCP Tools

Once connected, Claude can use these tools:

  • 🔍 search_documentation: Search for content across all documentation

  • 📚 get_documentation_sections: List all available sections

  • 📄 get_page_content: Get full content of specific pages

  • 🗂️ browse_section: Browse pages within a section

  • 📊 get_documentation_stats: Get database statistics

🔧 Command Line Tools

Documentation Scraper

# Basic scraping python docs_scraper.py # Override config settings python docs_scraper.py # Settings from config.py

Query Tool

# Search for content python query_docs.py --search "authentication guide" # Browse specific sections python query_docs.py --section "api-reference" # Get database statistics python query_docs.py --stats # List all sections python query_docs.py --list-sections # Export section to file python query_docs.py --export-section "tutorials" --format markdown > tutorials.md # Use custom database python query_docs.py --db "custom/path/docs.db" --search "example"

Debug Tools

# Test scraper functionality python utils/debug_scraper.py # Test MCP server python utils/debug_mcp_server.py # Test MCP tools directly python utils/debug_mcp_client.py # Test MCP protocol python utils/debug_mcp_server_protocol.py # Debug content extraction python utils/debug_site_content.py # Generate MCP config files python utils/gen_mcp.py

📊 Database Schema

Pages Table

CREATE TABLE pages ( id INTEGER PRIMARY KEY, url TEXT UNIQUE NOT NULL, title TEXT, content TEXT, markdown TEXT, word_count INTEGER, section TEXT, subsection TEXT, scraped_at TIMESTAMP, metadata TEXT );

Full-Text Search

-- Search using FTS5 SELECT * FROM pages_fts WHERE pages_fts MATCH 'your search term'; -- Or use the query tool python query_docs.py --search "your search term"

🎯 Example Use Cases

1. Documentation Analysis

# Get overview of documentation python query_docs.py --stats # Find all tutorial content python query_docs.py --search "tutorial guide example" # Export specific sections python query_docs.py --export-section "getting-started" > onboarding.md

2. AI Integration with Claude

# Once MCP is set up, ask Claude: # "Search the documentation for authentication examples" # "What sections are available in the documentation?" # "Show me the content for the API reference page"

3. Custom Applications

import sqlite3 # Connect to your scraped documentation conn = sqlite3.connect('docs_db/documentation.db') # Query for specific content results = conn.execute(""" SELECT title, url, markdown FROM pages WHERE section = 'tutorials' AND word_count > 500 ORDER BY word_count DESC """).fetchall() # Build your own tools on top of the structured data

📈 Performance and Optimization

Scraping Performance

  • Start small: Use max_pages=50 for testing

  • Adjust depth: max_depth=2 covers most content efficiently

  • Rate limiting: Increase delay_between_requests if getting blocked

  • Caching: Enabled by default for resumable crawls

Database Performance

  • Full-text search: Automatic FTS5 index for fast searching

  • Indexing: Optimized indexes on URL and section columns

  • Word counts: Pre-calculated for quick statistics

MCP Performance

  • Configurable limits: Set appropriate search and section limits

  • Snippet length: Adjust snippet size for optimal response times

  • Connection pooling: Efficient database connections

🌐 Supported Documentation Sites

This scraper works with most documentation websites including:

  • Static sites: Hugo, Jekyll, MkDocs, Docusaurus

  • Documentation platforms: GitBook, Notion, Confluence

  • API docs: Swagger/OpenAPI documentation

  • Wiki-style: MediaWiki, TiddlyWiki

  • Custom sites: Any site with consistent HTML structure

Site-Specific Configuration

Customize URL filtering and content extraction for your target site:

URL_FILTER_CONFIG = { "skip_patterns": [ r'/api/', # Skip API endpoint docs r'/edit/', # Skip edit pages r'\.pdf$', # Skip PDF files ], "allowed_domains": ["docs.yoursite.com"], } CONTENT_FILTER_CONFIG = { "remove_patterns": [ r'Edit this page.*?\n', # Remove edit links r'Was this helpful\?.*?\n', # Remove feedback sections ], }

🤝 Contributing

We welcome contributions! Here are some areas where you can help:

  • New export formats: PDF, EPUB, Word documents

  • Enhanced content filtering: Better noise removal

  • Additional debug tools: More comprehensive testing

  • Documentation: Improve guides and examples
