WHY IT NEEDS A POLICY

Why memory_create_event needs a policy

The 'create' verb in the tool name suggests reversible data creation (Write category). Without a detailed description, confidence is moderate. In the context of an Amazon MQ management server, creating an event likely adds a log or notification entry, which is modifiable or deletable, not irreversible.

From the tool's definition Tool name 'memory_create_event' indicates creation of an event record. The description is empty, limiting certainty. Based on the name pattern ('create'), this appears to create a new event entity within the Amazon MQ broker management context.
