Security Report

1.2

Use Caution1.2Critical Risk

This code executor MCP server has significant security concerns despite claiming safety guards. The server implements code execution with regex-based sandboxing that can be bypassed, performs unauthenticated external network calls to a metering endpoint without proper error handling, stores usage data in memory without security controls, and contains misleading documentation that contradicts actual behavior (claims read-only but executes arbitrary code). The auth middleware implements fail-open behavior that could allow unlimited access, and the overall architecture prioritizes monetization over security. Supply chain analysis found 3 known vulnerabilities in dependencies (0 critical, 3 high severity). Package verification found 1 issue.
