Security Report
4.2
Use Caution4.2High RiskThis MCP server is a straightforward CPF lookup tool with appropriate authentication via environment variables and sensible permission scope. Code quality is generally good with proper error handling. The main concerns are minor input validation gaps (CPF format validation) and a slightly unusual API call pattern in get_quota_info that could be simplified, but these do not present security vulnerabilities. Supply chain analysis found 7 known vulnerabilities in dependencies (0 critical, 5 high severity). Package verification found 1 issue.
