Server has well-structured tool definitions with complete schemas and descriptions. All 6 tools use Zod for input validation with proper types. Descriptions are clear and action-oriented (avg ~120 chars). However, output schemas are not documented, responses are returned as raw JSON without specifying expected fields. Error handling is minimal (generic API errors). Tool composition is sound: search_businesses → get_business follows a logical chain. No security issues detected (no secrets in params). Main gaps: missing output schema documentation, no error recovery guidance, no pagination metadata in search results despite potentially large result sets.

• Document output schemas for all tools. Specify expected fields, types, and structure. Example: 'Returns array of {id, name, category, city, country, logo_url, available_details, scores}' for search_businesses.
• Add error classification and recovery guidance. Replace generic 'API error 400: ...' with 'Invalid country code. Must be ISO 3166-1 alpha-2 (e.g., DE, AT, US). Try suggest() to discover valid codes.'
• For search_businesses, return pagination metadata: total_count, page, pages_remaining, next_cursor. Document in description: 'Results capped at limit; use page param to fetch additional results.'
• Clarify send_feedback response structure and side effects. Document: 'Returns {success: boolean, feedback_id: string, message: string}. Feedback is queued for review; no immediate data changes.'
• For get_business batch calls, document per-item error handling: 'Returns array with per-item success/failure. If one ID is invalid, others still process. Check each item's error field.'
