Crawl4AI Web Scraper

Security checks across malware telemetry and agentic risk

Overview

This skill transparently sends user-requested crawl jobs to a configured Crawl4AI service and does not show hidden, destructive, or persistent behavior.

Install this only if you intend to use a Crawl4AI instance you control or trust. Set CRAWL4AI_URL deliberately, and only set CRAWL4AI_KEY for a trusted endpoint because that service will receive the bearer token and the URLs you ask it to crawl.
