Manage Google Cloud Storage — list buckets, objects, create/delete buckets.
AI agents call gcp_storage to permanently remove resources in RedisNexus — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The tool spans Read (list buckets/objects), Write (create buckets), and Destructive (delete buckets). Per the rules, the most severe applicable category wins. Deleting a GCS bucket — especially one containing objects — is irreversible and can cause significant data loss in a production environment, making this Destructive with high severity.
From the tool's definition 'create/delete buckets' — the tool explicitly supports deleting GCS buckets, which is an irreversible destructive operation
Attacks that exploit this kind of access
Manage Google Cloud Storage — list buckets, objects, create/delete buckets. It is categorised as a Destructive tool in the RedisNexus MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the RedisNexus MCP server in PolicyLayer and add a rule for gcp_storage: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches RedisNexus. Nothing to install.
gcp_storage is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the gcp_storage rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for gcp_storage. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
gcp_storage is provided by the RedisNexus MCP server (rajkumar-madhu/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
