Column-Level Permissions: Essential Protection for AI Database Agents

Unrestricted database access for AI agents dramatically increases the risk of sensitive data exposure, especially when tables contain both operational and sensitive fields. The industry standard should be implementing column-level permissions, field masking, and approved projections—shifting the responsibility for data security from the AI model to the infrastructure layer. This architectural approach, supported by systems like MCP and audit logging, ensures that agents only access data they actually need.
