What gcp_compute_delete_disk does on GCP MCP Server
AI agents call gcp_compute_delete_disk to permanently remove resources in GCP MCP Server, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Why gcp_compute_delete_disk is rated Critical
This tool performs an irreversible deletion operation on cloud infrastructure. Once a persistent disk is deleted, the data cannot be recovered. This represents maximum blast radius in a cloud environment—accidental or malicious deletion could destroy application data, databases, or backups. This clearly maps to the Destructive category (irreversibly deletes data) rather than Write (reversible modifications).
From the tool's definition Tool name explicitly contains 'delete_disk' and description states 'Delete a persistent disk'. Persistent disks in GCP are storage volumes that can persist data indefinitely; deletion is irreversible and results in permanent data loss.
Attacks that exploit this kind of access
The rule that runs gcp_compute_delete_disk safely
PolicyLayer is an MCP gateway: it sits between your AI agents and GCP MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For gcp_compute_delete_disk, this is the rule to start with:
gcp_compute_delete_disk is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
The button opens the PolicyLayer dashboard: create your workspace, connect GCP MCP Server, apply this rule, and every gcp_compute_delete_disk call is checked against it from then on.
Questions about gcp_compute_delete_disk
Delete a persistent disk. It is categorised as a Destructive tool in the GCP MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the GCP MCP Server MCP server in PolicyLayer and add a rule for gcp_compute_delete_disk: 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 GCP MCP Server. Nothing to install.
gcp_compute_delete_disk 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_compute_delete_disk 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_compute_delete_disk. 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_compute_delete_disk is provided by the GCP MCP Server MCP server (ahmedselimmansor-ctrl/gcp_mcp_server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
