📖 Usage

Available Tools

`scrape_url`

Scrape a single URL for specific keywords

result = await scrape_url(
    url="https://example.com",
    keywords=["python", "automation", "scraping"],
    extract_links=False,
    max_depth=1
)

`search_and_scrape`

Search the web and automatically scrape results

result = await search_and_scrape(
    query="web scraping best practices",
    keywords=["python", "beautifulsoup", "requests"],
    search_engine_url="https://searx.gophernuttz.us/search/",
    max_results=10
)

`get_scraping_results`

Query the database for previous scraping results

result = await get_scraping_results(
    keyword_filter="python",
    limit=50
)

`export_results`

Export results to various formats

result = await export_results(
    format="markdown",
    keyword_filter="python",
    output_path="/path/to/output.md"
)

`get_scraping_stats`

Get current statistics and status

result = await get_scraping_stats()

🗃️ Database Schema

The agent uses SQLite with the following structure:

-- URLs table
CREATE TABLE urls (
    id INTEGER PRIMARY KEY AUTOINCREMENT,
    url TEXT UNIQUE NOT NULL,
    title TEXT,
    content TEXT,
    timestamp DATETIME DEFAULT CURRENT_TIMESTAMP
);

-- Keywords table  
CREATE TABLE keywords (
    id INTEGER PRIMARY KEY AUTOINCREMENT,
    keyword TEXT UNIQUE NOT NULL
);

-- URL-Keyword relationships
CREATE TABLE url_keywords (
    id INTEGER PRIMARY KEY AUTOINCREMENT,
    url_id INTEGER,
    keyword_id INTEGER,
    matches INTEGER DEFAULT 1,
    context TEXT,
    FOREIGN KEY (url_id) REFERENCES urls (id),
    FOREIGN KEY (keyword_id) REFERENCES keywords (id),
    UNIQUE(url_id, keyword_id)
);

🔧 Configuration

Default Settings

Max Depth: 3 levels of recursive crawling
Request Delay: 1 second between requests
User Agent: Modern Chrome browser simulation
Database: scraper_results.db (auto-created)

Customization

Modify settings in the MCPWebScraper constructor:

scraper = MCPWebScraper(
    db_manager=db_manager,
    max_depth=5,      # Increase crawl depth
    delay=0.5         # Faster requests
)
