mcp-oauth-server

The server demonstrates good security practices including adherence to OAuth 2.1 specifications like PKCE (Proof Key for Code Exchange) for authorization code flow. It implements rate limiting on critical endpoints (authorization, token, revocation, client registration) to prevent abuse and brute-force attacks. Client secrets are dynamically generated using cryptographically secure methods. It enforces HTTPS for issuer URLs in production (with a development override warning). CORS is enabled for public endpoints which is standard for an OAuth Authorization Server. No direct use of `eval` or obvious hardcoded sensitive secrets were found. However, for production, it explicitly requires a custom, persistent storage backend, as the default is in-memory.
