crawl-mcp

The project demonstrates awareness of security, including safeguards against ReDoS attacks using `_safe_regex_findall` with process-level timeouts, and secure file permissions (`0600`) for session/cache data. Environment variables are used for sensitive data like API keys. The `execute_js` parameter for crawling tools is powerful and, if misused by the client, could potentially execute arbitrary JavaScript within the browser context (though contained by Playwright/Chromium sandbox). The use of `--no-sandbox` in Docker Compose is a common practice for Playwright in containers but means reliance on Docker's isolation for browser sandboxing. Session data is stored in plaintext locally, albeit with restricted file permissions, posing a minor risk if the host system is compromised.
