Server has 7 well-named tools with clear action verbs (get_, search_, filter_, find_). All tools have descriptions (avg ~120 chars, within baseline 34-392). Input schemas are present with type definitions and parameter descriptions. However, output schemas are NOT documented, responses are returned as JSON strings without formal schema declarations. Error handling is minimal (returns plain text error messages without recovery guidance). No tool annotations (readOnlyHint, destructiveHint, idempotentHint) despite all tools being READ_ONLY. Parameter descriptions are adequate but lack explicit constraints (e.g., similarity_threshold 0-1 is mentioned but not formalized). Missing pagination documentation for list-returning tools (search_medicines, filter_medicines, find_alternatives).

• Add formal output schema documentation to all tools. Example: 'Returns: {medicine: {Name: string, Manufacturer: string, MRP: number, Composition: string, ...}, alternatives: [{...}]}'. This enables LLM planning.
• Add readOnlyHint: true to all tool definitions via FastMCP decorator or schema. Agents need to know these tools are safe to retry and have no side effects.
• Document pagination for search_medicines, filter_medicines, find_alternatives. Add 'Results are limited to max_results. For more, call again with different query parameters.' and consider adding offset/cursor support.
• Enhance error messages with recovery hints. E.g., 'Medicine "X" not found. Try search_medicines(query="X") for fuzzy matching.' This guides agent self-correction.
• Formalize numeric constraints in JSON Schema. Add 'minimum': 0, 'maximum': 1 to similarity_threshold; 'minimum': 1 to max_results. Remove constraint text from descriptions and rely on schema.
