Server has 10 tools with basic naming and descriptions, but significant gaps in schema completeness, parameter documentation, and error handling. All tools return unstructured strings instead of structured JSON. Parameter descriptions are minimal (avg ~15 chars). No input validation, no error recovery guidance, no pagination support for list operations. Output formatting functions exist but responses are markdown strings, not typed objects. This is a typical community-grade server with functional tools but production-unfriendly definitions.

• Convert all tool responses from markdown strings to typed JSON objects. E.g., get_boards should return {boards: [{id, name, url, dateLastActivity}], total: N} instead of formatted markdown.
• Add pagination to list operations: add limit (default 20, max 100) and offset parameters. Return total_count and next_offset in responses to enable agent-driven pagination.
• Expand parameter descriptions to 50-200 chars with format hints. E.g., 'board_id: The unique Trello board identifier (alphanumeric, 24 chars). Find it in the board URL: trello.com/b/{board_id}/...'
• Wrap API calls in try-except blocks. Return structured error responses with error_code, message, and recovery_hint. E.g., {error: 'board_not_found', message: 'Board ID invalid or access denied', hint: 'Verify board_id with get_boards() first'}
• Add input validation and constraints. E.g., validate board_id format, enforce max description length for create_card, document that due dates must be ISO 8601 strings.
