Security Report
This is a well-structured MCP server for email compatibility analysis with proper authentication patterns for optional hosted features. The codebase shows good security practices: API keys are loaded from environment variables (not hardcoded), sensitive operations require explicit authentication checks, and input validation is consistently applied. Permissions align appropriately with the server's stated purpose (email analysis via APIs, local file-free processing, and optional network calls for screenshots/sharing). Minor code quality observations exist around error handling consistency, but no security vulnerabilities or dangerous patterns were identified. Supply chain analysis found 3 known vulnerabilities in dependencies (0 critical, 3 high severity). Package verification found 1 issue.
