mcp-porkbun-domain-availability

The server correctly uses environment variables for API keys and secrets, preventing hardcoding. It uses Zod for input schema validation, which helps prevent malformed inputs. Domain names are directly interpolated into the API endpoint URL; while standard for domain lookups, it's a general point to consider for URL injection, though domain name formats are restrictive. No 'eval' or other obvious malicious patterns were found. Network requests are made to a specific, hardcoded Porkbun API endpoint. The implementation includes built-in rate limiting and comprehensive error handling.
