WHAT IT DOES

What delete_group does on Proxmox MCP Server

AI agents call delete_group 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.

RISK

Why delete_group is rated Critical

This tool permanently removes a group from Proxmox VE infrastructure. Group deletion cannot be undone and destroys access control configurations, potentially orphaning permissions and breaking authentication workflows. This is irreversible destruction of infrastructure metadata, making it Destructive rather than Write.

From the tool's definition Tool name is 'delete_group' with description 'Delete a group.' The verb 'delete' explicitly indicates irreversible removal of data (a group resource in Proxmox).

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs delete_group 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_group, this is the rule to start with:

delete_group Hidden

delete_group is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
