Security Report

5.2
Moderate5.2Moderate Risk

This is a well-structured MCP server for text-to-speech synthesis with proper authentication and appropriate permissions. The code properly validates the API key at startup, handles input validation for text length and content, and makes authenticated API calls to an external TTS service. Minor code quality issues around broad exception handling do not materially impact security. Supply chain analysis found 5 known vulnerabilities in dependencies (0 critical, 5 high severity). Package verification found 1 issue.
