Server has 5 tools with visible schemas and descriptions, but quality is significantly below production baseline. Tool names lack clear action verbs (say_hi is non-standard). Descriptions are minimal (10-50 chars, well below 194-char baseline). Parameter descriptions are sparse or missing entirely, most params lack any guidance on format, constraints, or purpose. No output schemas documented. Error handling is present but minimal. The execute_update tool exposes destructive operations without confirmation or dry-run support. Overall, this reads as a prototype rather than production-ready tooling.

• Add detailed parameter descriptions to all tools. For 'query' params, specify: 'A valid SQL query string. For execute_query, only SELECT statements are allowed. For execute_update, INSERT/UPDATE/DELETE/CREATE/DROP are allowed. Max 10,000 characters.'
• Document output schemas in tool metadata. E.g., list_tables returns {type: 'array', items: {type: 'object', properties: {table_name: {type: 'string'}}}}.
• Expand tool descriptions to 100-200 chars. Example: 'Execute a SELECT query against the database. Use this to retrieve data. Returns structured results as JSON. For schema discovery, call describe_table first. Queries timeout after 30 seconds.'
• Add a confirmation step or dry-run mode to execute_update. E.g., add a 'dry_run' boolean parameter that returns the query plan without executing, or require explicit 'confirm: true' parameter.
• Remove or rename say_hi. It is a demo tool that adds no value in production. If kept for testing, document it as such and exclude from agent tool lists.
