Security

  • API key authentication with SHA-256 hashing

  • Role-Based Access Control (RBAC) with granular permissions

  • Input validation via Zod schemas

  • SQL injection protection via Prisma ORM

  • Audit logging for every tool call

  • Safe file upload with type allowlist and size limits

  • No secrets in code — all via environment variables

  • Structured error responses (no stack traces in production)
