Security Report

4.2

Use Caution4.2High Risk

Kiln is a well-architected MCP server for 3D printer control with reasonable security practices. Authentication is optional but properly gated for sensitive operations. Code quality is high with input validation and error handling throughout. Permissions (network, env vars, file I/O) are appropriate for a multi-printer orchestration tool. Minor concerns around credential handling in environment variables and some broad exception catching do not significantly impact the score. Supply chain analysis found 18 known vulnerabilities in dependencies (0 critical, 6 high severity). Package verification found 1 issue.
