WHAT IT DOES

What manage_customers does on Pancake POS MCP

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

WHY IT NEEDS A POLICY

Why manage_customers needs a policy

The tool primarily manages customer data with reversible operations (create, update, add_note), making it fundamentally a Write operation. While it includes a delete function (which would be Destructive if that were the sole focus), the balanced action set indicates customer lifecycle management rather than data destruction.

From the tool's definition Tool supports 'create, update, delete' operations on customer data, plus 'add_note' and 'reward_history' modifications.
