Security Report

2.0

Use Caution2.0Critical Risk

This MCP server provides a code execution sandbox for Python, JavaScript, and SQL, but contains critical security vulnerabilities that make it unsafe for production use. The server exposes hardcoded Coinbase CDP API credentials in plaintext (API key ID and secret), implements arbitrary code execution without proper sandboxing, and lacks adequate input validation. These issues represent real security risks that users should be aware of. Supply chain analysis found 5 known vulnerabilities in dependencies.
