Security Report

3.2
Use Caution3.2High Risk

This MCP server implements a pay-per-call model using x402 micropayments on Solana with reasonable architecture. However, several security concerns warrant attention: the server executes arbitrary code review on user submissions without sandboxing, makes unauthenticated external API calls (Grok, Google Search, web scraping), stores no input validation for potentially malicious URLs, and lacks comprehensive error handling that could leak sensitive information. The permission scope is appropriate for a developer tools server, but the code execution and external API integration patterns present moderate risks. Supply chain analysis found 12 known vulnerabilities in dependencies (0 critical, 6 high severity). Package verification found 1 issue (1 critical, 0 high severity).
