What delete_sdn_zone does on Proxmox MCP Server
AI agents call delete_sdn_zone to permanently remove resources in Proxmox MCP Server, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Why delete_sdn_zone is rated Critical
Deleting an SDN (Software-Defined Networking) zone is a destructive operation that cannot be undone and will remove network configuration affecting potentially multiple virtual machines and containers in the Proxmox infrastructure. This has significant blast radius if triggered erroneously by an AI agent, justifying 'high' severity. Confidence is high because the intent is unambiguous from both name and description.
From the tool's definition Tool name is 'delete_sdn_zone' and description states 'Delete an SDN zone.' The verb 'delete' and explicit deletion of a network infrastructure zone indicate irreversible removal of data/configuration.
Attacks that exploit this kind of access
The rule that runs delete_sdn_zone safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Proxmox MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For delete_sdn_zone, this is the rule to start with:
delete_sdn_zone 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 Proxmox MCP Server, apply this rule, and every delete_sdn_zone call is checked against it from then on.
Questions about delete_sdn_zone
Delete an SDN zone. It is categorised as a Destructive tool in the Proxmox MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Proxmox MCP Server MCP server in PolicyLayer and add a rule for delete_sdn_zone: 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 Proxmox MCP Server. Nothing to install.
delete_sdn_zone 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 delete_sdn_zone 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 delete_sdn_zone. 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.
delete_sdn_zone is provided by the Proxmox MCP Server MCP server (gethosthewalrus/proxmox-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
