  • Zero dependencies (Node.js >=18 native fetch / FormData).

  • Two transports supported:

    1. Remote Streamable HTTP MCP (zero local install): https://kaijuconverter.com/api/mcp

    2. Local Stdio MCP + CLI (supports converting local files on disk): npx -y https://kaijuconverter.com/downloads/kaijuconverter-mcp.tgz

  • Privacy & Security: Cryptographic SHA-256 output verification + automatic 60-minute GDPR file shredding (Security Architecture).
