MedifinderMCP has basic tool structure but significant quality gaps. All 8 tools have descriptions and most have input schemas, but descriptions are generic (avg ~60 chars, well below the 194-char baseline). Parameter descriptions are sparse or missing entirely. No output schemas documented. Error handling returns generic database errors without recovery guidance. Tools like search_medicines and get_medicine_locations have reasonable parameter typing, but get_regional_statistics and get_medicine_status have empty input schemas. The create_database_schema tool is a write operation but lacks confirmation/dry-run patterns. No tool annotations (readOnlyHint/destructiveHint) present despite clear risk classifications.

• Add explicit output schemas to all tools. Document the structure of 'results' array in search_medicines (e.g., [{id, name, category, stock}, ...]), and return type for get_medicine_stock (e.g., {id, name, total_stock, months_of_supply, inventory: [...]}).
• Expand parameter descriptions. search_medicines.search_type should document: 'Type of search: "name" searches by medicine name; "location" searches by DIRESA region and requires location parameter.' Add constraints like 'limit must be 1-100'.
• Add recovery guidance to error responses. E.g., 'Medicine not found. Try search_medicines() with a partial name or different search_type.' Categorize errors as retryable vs user-fixable.
• Implement confirmation pattern for create_database_schema. Add a dry_run parameter (default true) that returns what would be created without executing, or require explicit confirm=true to proceed.
• Add tool annotations via FastMCP. Mark read-only tools with readOnlyHint=true and create_database_schema with destructiveHint=true so LLMs understand safety implications without reading descriptions.

• Relies on Logging (deprecated) - log to stderr or use OpenTelemetry
