Delete a Hetzner Cloud server. Deleting is free and stops billing, but it destroys the server, so it requires confirm true. Auto-created primary IPs are released by Hetzner shortly after.
AI agents call cloud_delete_server to permanently remove resources in Hetzner — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently and irreversibly deletes a cloud server, which is the textbook definition of a Destructive action. The blast radius is critical because: (1) the deletion is permanent and cannot be undone, (2) any data stored on the server is lost, (3) services running on the server are immediately halted, and (4) the requirement for explicit confirmation (confirm true) indicates the developers recognized the…

Register the Hetzner MCP server in PolicyLayer and add a rule for cloud_delete_server: 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 Hetzner. Nothing to install.
cloud_delete_server 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 cloud_delete_server 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 cloud_delete_server. 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.
