What storage_bucket_create does on Yaver

RISK

Why storage_bucket_create is rated Medium

Creating an S3 bucket is a Write operation—it creates a new persistent resource in cloud storage that persists until explicitly deleted. While the action itself is reversible (the bucket can be deleted), it commits cloud infrastructure changes and incurs potential costs.

From the tool's definition Tool name 'storage_bucket_create' and description 'Create an S3 bucket' indicate irreversible creation of cloud infrastructure resource.

RECOMMENDED RULE

The rule that runs storage_bucket_create safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Yaver, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For storage_bucket_create, this is the rule to start with:

storage_bucket_create Rate-limited

storage_bucket_create stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
