web-scraper-toolkit 0.1.2

A powerful, standalone web scraping toolkit using Playwright and various parsers.

🕷️ Web Scraper Toolkit & MCP Server

Version: 0.1.2
Status: Production Ready
Expertly Crafted by: Roy Dawson IV

A production-grade, multimodal scraping engine designed for AI Agents. Converts the web into LLM-ready assets (Markdown, JSON, PDF) with robust anti-bot evasion.

🚀 The "Why": AI-First Scraping

In the era of Agentic AI, tools need to be more than just Python scripts. They need to be Token-Efficient, Self-Rectifying, and Structured.

✨ Core Design Goals

• 🤖 Hyper Model-Friendly: All tools return standardized JSON Envelopes, separating metadata from content to prevent "context pollution."
• �️ Robust Failover: Smart detection of anti-bot challenges (Cloudflare/403s) automatically triggers a switch from Headless to Visible browser mode to pass checks.
• 🎯 Precision Control: Use CSS Selectors (selector) and token limits (max_length) to extract exactly what you need, saving tokens and money.
• � Batch Efficiency: The explicit batch_scrape tool handles parallel processing found in high-performance agent workflows.
• ⚡ MCP Native: Exposes a full Model Context Protocol (MCP) server for instant integration with Claude Desktop, Cursor, and other agentic IDEs.
• 🔒 Privacy & Stealth: Uses playwright-stealth and randomized user agents to mimic human behavior.

📦 Installation

Option A: PyPI (Recommended)

Install directly into your environment or agent container.

pip install web-scraper-toolkit
playwright install

Option B: From Source (Developers)

git clone https://github.com/imyourboyroy/WebScraperToolkit.git
cd WebScraperToolkit
pip install -e .
playwright install

---

🔌 MCP Server Integration

This is the primary way to use the toolkit with AI models. The server runs locally and exposes tools via the Model Context Protocol.

Running the Server

Once installed, simply run:

web-scraper-server --verbose

Connecting to Claude Desktop / Cursor

Add the following to your agent configuration:

{
  "mcpServers": {
    "web-scraper": {
      "command": "web-scraper-server",
      "args": ["--verbose"],
      "env": {
        "SCRAPER_WORKERS": "4"
      }
    }
  }
}

🧠 The "JSON Envelope" Standard

To ensure high reliability for Language Models, all tools return data in this strict JSON format:

{
  "status": "success",  // or "error"
  "meta": {
    "url": "https://example.com",
    "timestamp": "2023-10-27T10:00:00",
    "format": "markdown"
  },
  "data": "# Markdown Content of the Website..."  // The actual payload
}

Why? This allows the model to instantly check .status and handle errors gracefully without hallucinating based on error text mixed with content.

🛠️ Available MCP Tools

Tool	Description	Key Args
scrape_url	The Workhorse. Scrapes a single page.	url, selector (CSS), max_length
batch_scrape	The Time Saver. Parallel processing.	urls (List), format
deep_research	The Agent. Search + Crawl + Report.	query
search_web	Standard Search (DDG/Google).	query
crawl_site	Discovery tool for Sitemaps.	url
save_pdf	High-fidelity PDF renderer.	url, path
configure_scraper	Dynamic configuration.	headless (bool), user_agent

---

💻 CLI Usage (Standalone)

For manual scraping or testing without the MCP server:

# Basic Markdown Extraction (Best for RAG)
web-scraper --url https://example.com --format markdown

# High-Fidelity PDF with Auto-Scroll
web-scraper --url https://example.com --format pdf

# Batch process a list of URLs from a file
web-scraper --input urls.txt --format json --workers 4

# Sitemap to JSON (Site Mapping)
web-scraper --input https://example.com/sitemap.xml --site-tree --format json

🛠️ CLI Reference

Option	Shorthand	Description	Default
--url	-u	Single target URL to scrape.	None
--input	-i	Input file (.txt, .csv, .json, sitemap .xml) or URL.	None
--format	-f	Output: markdown, pdf, screenshot, json, html.	markdown
--headless		Run browser in headless mode. (Off/Visible by default for stability).	False
--workers	-w	Number of concurrent workers. Pass max for CPU - 1.	1
--merge	-m	Merge all outputs into a single file.	False
--site-tree		Extract URLs from sitemap input without crawling.	False
--verbose	-v	Enable verbose logging.	False

🤖 Python API

Integrate the WebCrawler directly into your Python applications.

import asyncio
from web_scraper_toolkit import WebCrawler, ScraperConfig

async def agent_task():
    # 1. Configure
    config = ScraperConfig.load({
        "scraper_settings": {"headless": True}, 
        "workers": 2
    })
    
    # 2. Instantiate
    crawler = WebCrawler(config=config)
    
    # 3. Run
    results = await crawler.run(
        urls=["https://example.com"],
        output_format="markdown",
        output_dir="./memory"
    )
    print(results)

if __name__ == "__main__":
    asyncio.run(agent_task())

⚙️ Server Configuration

You can configure the MCP server via Environment Variables:

Variable	Description	Default
SCRAPER_WORKERS	Number of concurrent browser processes.	1
SCRAPER_VERBOSE	Enable debug logs (true/false).	false
