Security Report
Helionyx is a well-architected renewable energy sizing MCP server with thoughtful security design. Authentication is optional but appropriately scoped for local-first operation; the codebase shows good defensive practices including input validation, error handling, and proper dependency management. Permissions are appropriate for a developer tool (network access for NASA POWER/PVGIS APIs, subprocess spawning for solvers). A few minor code quality observations exist, but no significant security vulnerabilities were identified. Supply chain analysis found 9 known vulnerabilities in dependencies (0 critical, 3 high severity). Package verification found 1 issue.
