Server has 7 tools with basic schemas and descriptions, but significant gaps limit production readiness. All tools have descriptions (10-100 chars, mostly adequate), and input schemas are present with type definitions. However, descriptions lack depth on WHEN to use each tool and dependencies between them. Parameter descriptions are minimal (e.g., 'Search query' for web_search). No output schemas documented. Error handling is present but generic. Tools like list_tickets and search_tickets have overlapping functionality with unclear distinction. The 'mine' parameter is a synthetic addition not in the actual API, adding complexity. No tool annotations (readOnlyHint, etc.) despite all being read-only operations.

• Document output schemas for all tools. Example: get_ticket should return {ticket_id, subject, status, priority, description, created_at, updated_at, agent_id, ...}. Include pagination info for list_tickets and search_tickets (total_count, page, per_page, has_more).
• Consolidate list_tickets and search_tickets into a single search_tickets tool with clear documentation: 'Use this to find tickets by status, priority, agent, tag, or custom query. Supports pagination via page parameter.'
• Expand parameter descriptions to 50-200 chars with context. Example: 'Search query using Freshdesk query syntax (field:value AND field:value). E.g., status:2 AND priority:4 AND agent_id:123. Use this to find tickets matching multiple criteria. For simple filters, use list_tickets instead.'
• Add readOnlyHint: true to all tool definitions in the MCP response. This signals to LLMs that these tools are safe to call without confirmation and can be retried on transient failures.
• Remove or clearly document the synthetic 'mine' parameter. If kept, add a note: 'Convenience parameter that expands to agent_id:{FRESHDESK_AGENT_ID} from .env. Requires FRESHDESK_AGENT_ID to be set.' Better: remove it and let LLMs compose queries explicitly.
