AI agents use product_adjust_stock to create or update resources in Database MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Database MCP Server environment.

WHY IT NEEDS A POLICY

Why product_adjust_stock needs a policy

This tool modifies existing product stock quantity data in the database. It's reversible (stock can be incremented or decremented back), making it a Write rather than Destructive operation. Severity is medium because misuse could corrupt inventory data, leading to overselling or artificial stock manipulation, but it doesn't delete records or move money.

From the tool's definition Increment (or decrement) product stock by delta using product name
