- Scrape content from web pages
- Gather information from online sources
- Automate web data collection
How to use it
Basic Setup
- Add the Web Scraper tool to your workflow
- Connect its output to nodes that need web scraping capabilities (like an Agent)
Outputs
- tool: The configured web scraper tool that other nodes can use
Example

Implementation Details
The Web Scraper tool is implemented using Griptape's WebScraperTool class and provides a simple interface for extracting content from web pages. The tool is designed to be used by agents to gather information from websites in a structured way.
Important Notes
- The tool respects website terms of service and robots.txt files
- Performance may vary depending on the structure and complexity of websites
- Some websites may block automated scraping attempts
- The tool works best with text-based content rather than dynamic JavaScript-heavy sites
- Consider rate limiting and ethical use to avoid overloading websites
Common Issues
- Access Denied: Some websites actively block web scrapers
- Content Not Found: Dynamic content loaded via JavaScript might not be accessible
- Rate Limiting: Excessive requests may trigger rate limiting from websites
- Changing Layouts: Website structure changes can affect scraping reliability
- Processing Large Pages: Very large web pages may take longer to process or exceed token limits
