WHAT IT DOES

What delete_role does on Proxmox MCP Server

AI agents call delete_role 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_role is rated Critical

Deletion of roles is a destructive operation that cannot be undone. Removing a role could revoke permissions for users or groups, disrupt access control, and potentially lock users out of infrastructure management. While not as immediately catastrophic as deleting VMs or storage, role deletion is irreversible and impacts system security posture.

From the tool's definition Tool name is 'delete_role' with description 'Delete a role.' The verb 'delete' indicates irreversible removal of data (a role object in Proxmox).

RECOMMENDED RULE

The rule that runs delete_role 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_role, this is the rule to start with:

delete_role Hidden

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