playfab-mcp-server

The server demonstrates strong security practices for an LLM-controlled API gateway. It leverages environment variables for sensitive PlayFab credentials (PLAYFAB_TITLE_ID, PLAYFAB_DEV_SECRET_KEY), which are validated and not hardcoded. Logging redacts sensitive information like API keys and passwords. Crucially, all 'destructive' operations (e.g., delete_item, ban_users, delete_inventory_items) require an explicit 'ConfirmDeletion' or 'ConfirmBan' boolean flag to be set to 'true' in the input, acting as a critical safeguard against accidental or misinterpreted LLM commands. Input validation is also present in handlers to prevent malformed requests. The architecture uses a router for predefined handlers, limiting the attack surface to known API calls. While any system accepting LLM input requires continuous vigilance, the implemented safeguards are robust.
