WHAT IT DOES

What delete_user_token does on Proxmox MCP Server

AI agents call delete_user_token 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_user_token is rated Critical

This tool permanently removes API tokens, which cannot be undone. Deletion of authentication credentials is a destructive action with significant operational impact—loss of API access, broken integrations, or lockout scenarios. While not as severe as deleting VMs or data (hence 'high' not 'critical'), token deletion is irreversible and falls squarely into the Destructive category.

From the tool's definition Tool name 'delete_user_token' with description 'Delete an API token' explicitly performs irreversible deletion of authentication credentials.

RECOMMENDED RULE

The rule that runs delete_user_token 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_user_token, this is the rule to start with:

delete_user_token Hidden

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