This server has 14 tools with basic schemas and descriptions, but significant quality gaps prevent production recommendation. Most tools have minimal descriptions (10-50 chars, well below the 194-char baseline). Parameter descriptions are sparse or missing entirely. No output schemas are documented. Error handling is absent from visible code. Tool names follow verb_noun convention (get_tables, execute_reader) but lack context about when to use each. The execute_nonquery and execute_routine tools accept free-form SQL/parameters without validation guidance, inviting injection attacks. No evidence of pagination, result limits, or structured output shaping. Security concerns: SQL parameters exposed directly, no mention of permission gates or audit trails.

• Document output schemas for all 14 tools. Example: execute_reader should return {rows: [{col1: string, col2: number, ...}], rowCount: number, executionTimeMs: number}.
• Expand descriptions to 100-200 chars. Add WHEN to use, prerequisites, and state-modification warnings. E.g., 'Executes SELECT statements and returns results. Call this to retrieve data. Returns up to 1000 rows; use limit parameter for pagination.'
• Add validation and constraint guidance to execute_nonquery and execute_routine parameters. Describe allowed SQL dialects, parameter format (e.g., @paramName or :paramName), and injection prevention.
• Implement pagination: add limit (default 20, max 1000) and offset/cursor parameters to all list/get tools. Return total_count and next_cursor in responses.
• Add error handling: categorize failures as retryable (timeout, connection) vs user-fixable (invalid SQL, missing table). Return actionable messages like 'Table not found. Available tables: [list]' instead of raw errors.
