Remove an empty bucket from MinIO
AI agents call minio_remove_bucket to permanently remove resources in MinIO MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool falls into the Destructive category because it permanently removes a bucket from MinIO object storage. Although it requires the bucket to be empty (preventing mass data deletion in a single operation), the removal itself is irreversible. An AI agent with access to this tool could disable storage infrastructure, break application deployments, or cause service disruptions.
From the tool's definition The tool name 'minio_remove_bucket' combined with the description 'Remove an empty bucket from MinIO' indicates irreversible deletion of storage infrastructure.
