Server has 15 well-named tools with mostly complete schemas and descriptions. Naming follows verb_noun convention (search_, lookup_, create_, update_, log_, list_, delete_, get_, set_). Descriptions are present and contextual (avg ~150 chars), though some lack explicit guidance on when to use vs. similar tools. All tools have input schemas with types and descriptions. Output schemas are not documented, LLMs cannot predict response structure. Error handling is minimal; no recovery guidance. Parameter constraints are good (enums for meal types, activity levels, sex). Missing: idempotency guidance, confirmation patterns for destructive ops (delete_entry, delete_activity), and output schema documentation.

• Document output schemas for all tools. For search_foods, specify: {id: integer, name: string, brand: string|null, kcal100: number, serving: number|null}. For list_entries, specify array of {id, foodId, label, quantityG, date, meal, kcal, protein, carbs, fat}.
• Add confirmation pattern to delete_entry and delete_activity. Require a confirm_delete parameter or return a confirmation_token that must be passed in a follow-up call.
• Implement error handling with recovery guidance. Return {error: string, code: string, retryable: boolean, suggestion: string}. E.g., 'Food not found. Try search_foods() first.' for missing foodId.
• Expand descriptions for list_entries, list_activities, delete_entry, delete_activity, get_settings to 80-150 chars. Clarify when to use list_entries vs. get_daily_summary (daily summary is aggregated; list_entries is per-meal detail).
• Add limit and offset parameters to list_entries and list_activities. Document max results (e.g., 100) and return total_count for pagination.
