Strong schema definitions with proper enums and type constraints. All 7 tools have clear descriptions (avg 95 chars) and complete input schemas. Tool names follow verb_noun pattern (list_, get_, create_, update_, delete_). DNS record creation/update parameters are well-documented with conditional requirements (e.g., 'required for MX and SRV'). Main gaps: output schemas not documented in source; no pagination support for list_domains/list_dns_records despite potentially large result sets; error handling guidance minimal.

• Document output schemas for all tools. Example: list_domains returns {domains: [{id, domain, expiry_date, status, ...}], total: number}. Include this in tool registration or README.
• Add pagination to list_domains and list_dns_records: accept limit (1-100, default 20) and offset parameters; return total count and next_offset. Cap results at 50 items per call.
• Refactor create_dns_record and update_dns_record to use conditional schema validation. For SRV records, mark priority/weight/port as required in the schema, not just the description.
• Enhance error messages with actionable guidance. E.g., catch validation errors and return: 'Invalid TTL 1000: must be 60-604800 and a multiple of 60. Try 3600 or 7200.'
• Add a dry_run parameter to create_dns_record and update_dns_record to let agents preview changes before committing. Reduces accidental DNS breakage.
