15-30 minutes including configuration and testing

• +Use read-only database credentials to prevent accidental writes
• +Connect to read replica, not production primary database
• +Set query timeout limits to prevent long-running queries
• +Document database schema and common queries for AI context
• +Monitor query performance and optimize slow queries
• +Use connection pooling for better performance
• +Test with non-production data first

• −Don't use production write credentials—risk of data corruption
• −Don't query production database during peak traffic hours
• −Don't expose sensitive PII without proper access controls
• −Don't skip query result validation—AI can misinterpret schema
• −Don't allow unlimited result set sizes—set LIMIT clauses
• −Don't share database credentials in plain text config files

Use for ad-hoc data queries, exploratory analysis, report generation, schema exploration, and democratizing data access. Best for read-heavy analytics workloads.

Avoid for production write operations, mission-critical transactions, real-time OLTP workloads, or when database contains sensitive PII without proper access controls. Use read replicas, not primary.
