TheFinalDiscordMCP

The server demonstrates strong security practices. It extensively uses a dedicated `SecurityUtils` class for input validation, sanitization (e.g., Discord snowflake IDs, command arguments), and robust SSRF prevention (whitelisting domains, blocking private IPs, and reconstructing URLs from validated components when downloading images). Role-based permission checks and hierarchy validation are consistently applied before performing sensitive Discord operations (moderation, channel/role management). CORS is explicitly configured to avoid wildcards in production. Hardcoded secrets are avoided, relying on environment variables. The use of Zod for schema validation adds an additional layer of input validation. Potential minor risks exist if the `ALLOWED_UPLOAD_DIRS` environment variable is misconfigured by the user to include sensitive system paths, or if `CORS_ALLOW_ALL` is set in production.
