WHAT IT DOES

What list_user_tokens does on Proxmox MCP Server

AI agents call list_user_tokens to retrieve information from Proxmox MCP Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why list_user_tokens is rated Low

This tool retrieves and enumerates API tokens for a user account, which is a read-only query operation. However, severity is elevated to medium rather than low because API tokens are sensitive security credentials—exposing their metadata (names, creation dates, expiration info, associated permissions) could aid an attacker in lateral movement or privilege escalation.

From the tool's definition Tool name 'list_user_tokens' and description 'List API tokens for a user' indicate retrieval of existing API token metadata without modification or deletion.

RECOMMENDED RULE

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

list_user_tokens Allowed

list_user_tokens is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

  "default": "deny",
  "tools": {
    "list_user_tokens": {}
  }

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Proxmox MCP Server, apply this rule, and every list_user_tokens call is checked against it from then on.
