Disable a Remnawave user (block VPN access)

How to control users_disable ↓

AI agents use users_disable to create or update resources in Remnawave — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Remnawave environment.

Medium Risk

This tool modifies user account state by disabling VPN access, which is a reversible write operation. While it impacts service availability for the user, it does not permanently delete data or cause financial transactions.

From the tool's definition Tool name 'users_disable' and description 'Disable a Remnawave user (block VPN access)' indicate modifying user access state.

Documented attack patterns abuse exactly the kind of access users_disable gives an agent:

PolicyLayer is an MCP gateway — it sits between your AI agents and Remnawave, and nothing reaches the server without passing your rules. This is the rule we recommend for users_disable:

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "users_disable": {
      "limits": [
        {
          "counter": "users_disable_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

users_disable stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

  1. Create a free account and register Remnawave — nothing to install.
  2. Add this policy — paste it, or build it visually.
  3. Point your MCP client (Claude, Cursor, anything) at your gateway URL.
