secrets-mcp-server-ui

The frontend code is well-structured and utilizes modern UI libraries (Radix UI, ShadCN), with no obvious `eval` usage, obfuscation, or hardcoded secrets. It employs `crypto.randomUUID()` for IDs, which is good practice. However, as a 'secrets manager,' the core security relies heavily on the underlying KV store provided by `@github/spark/hooks/useKV`. The Product Requirements Document (PRD) explicitly states that the application 'focuses on demonstrating MCP interface patterns rather than implementing actual OS-level cryptographic APIs,' which implies client-side encryption is not performed. If the `useKV` service does not automatically encrypt secrets at rest and in transit, storing sensitive data with this application would pose a significant security risk. The overall security posture for managing actual secrets is critically dependent on the unanalyzed `@github/spark` platform's KV implementation.
