Security Report

4.2

Use Caution4.2High Risk

CKG-MCP is a read-only knowledge graph traversal server with minimal security risk. No authentication is required for free domains, but this aligns with the server's stated purpose. The code is well-structured with proper input validation, no malicious patterns, and appropriate permissions for a developer tools category server. Minor code quality issues and reliance on environment variables for optional Pro feature authentication do not significantly impact the security posture. Supply chain analysis found 5 known vulnerabilities in dependencies (0 critical, 5 high severity). Package verification found 1 issue.
