WHY IT NEEDS A POLICY

Why create-serverless-cache needs a policy

The 'create' verb indicates reversible creation of a new resource (Write category). Severity is high because provisioning cloud resources can incur costs and create infrastructure that must be managed; misuse could lead to unexpected expenses and resource sprawl. Confidence is 0.75 rather than higher due to the empty tool description, which limits certainty about exact behavior and parameters.

From the tool's definition Tool name 'create-serverless-cache' indicates resource creation. Server description states it provisions and manages AMQ brokers; this tool creates a new serverless cache resource.
