Security Report

3.2

Use Caution3.2High Risk

This JavaScript reverse engineering MCP server has legitimate functionality for debugging and analyzing JS code, but exhibits several security concerns. The server grants broad browser access (eval, network inspection, script injection) with minimal input validation, uses anti-detection techniques designed to bypass security systems, and contains inadequate error handling around dynamic code execution. While permissions align with its stated purpose, the combination of unrestricted eval-like operations, anti-bot bypass features, and lack of auth safeguards warrants caution. Supply chain analysis found 3 known vulnerabilities in dependencies (0 critical, 3 high severity). Package verification found 1 issue (1 critical, 0 high severity).
