Security Report

5.6
Moderate5.6Moderate Risk

claudio-audiobook is a local text-to-speech MCP server that renders audiobooks with a bundled Kokoro model and ffmpeg, with no API keys required. The code shows careful handling of paths (only home expansion), no shell injection visible, and network use limited to package installs and a checksummed model download. Only minor observations remain; the server's permissions (file read/write, subprocess for ffmpeg/espeak, one-time model download) match its stated purpose. Supply chain analysis found 15 known vulnerabilities in dependencies (0 critical, 11 high severity). Package verification found 1 issue.
