Rollback a failed deployment
AI agents call rollback_deployment to permanently remove resources in Terragrunt GCP Tool MCP — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Rolling back a deployment in GCP infrastructure managed by Terragrunt involves destroying newly created resources and/or restoring previous configurations — operations that are irreversible with potentially broad blast radius across cloud infrastructure. This fits the Destructive category as it cannot be undone once executed.
From the tool's definition rollback_deployment — 'Rollback a failed deployment' implies reverting infrastructure state, which irreversibly destroys or overwrites currently deployed cloud resources to restore a previous state.
Attacks that exploit this kind of access
Rollback a failed deployment. It is categorised as a Destructive tool in the Terragrunt GCP Tool MCP MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Terragrunt GCP Tool MCP server in PolicyLayer and add a rule for rollback_deployment: 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 Terragrunt GCP Tool MCP. Nothing to install.
rollback_deployment 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 rollback_deployment 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 rollback_deployment. 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.
rollback_deployment is provided by the Terragrunt GCP Tool MCP server (spolspol/terragrunt-gcp-tool-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
