Single tool with basic schema and description. Tool name 'run_sql_query' is generic and lacks action clarity (verb_noun pattern weak, 'execute_select_query' would be clearer). Description is adequate (73 chars) but lacks WHEN to use it, prerequisites, or output format guidance. Input schema present with type and description, but no output schema documented. Error handling returns isError flag but lacks recovery guidance. No parameter constraints (e.g., max query length, timeout). Missing pagination, result limits, and structured output documentation.

• Add explicit output schema to tool definition: { type: 'object', properties: { rows: { type: 'array', items: { type: 'object' }, description: 'Query result rows' }, rowCount: { type: 'number' } }, required: ['rows', 'rowCount'] }
• Rename tool to 'query_products_database' or 'execute_select_query' for clarity. Avoid generic 'run_' prefix.
• Document result limits in description: 'Returns up to 1,000 rows. For larger datasets, use LIMIT and OFFSET in your query.'
• Enhance error messages with recovery hints: 'SQL syntax error. Ensure query is a valid SELECT statement. Check column names and table references.'
• Add query parameter constraints to description: 'Max 10,000 characters, 30-second execution timeout. Only SELECT statements allowed.'
