WHY IT NEEDS A POLICY

Why create_datastore needs a policy

The 'create_datastore' tool creates a new datastore resource, which is a reversible write operation. It modifies the infrastructure state by adding a new resource. While it doesn't delete data (hence not Destructive), it can have significant blast radius if misconfigured—creating wrong datastores could consume resources, incur costs, or disrupt services.

From the tool's definition Tool name is 'create_datastore' which indicates creation of a data storage resource. Context shows this is an Amazon MQ MCP Server for provisioning and managing AMQ brokers, suggesting infrastructure/resource creation.
