Update a subscription page configuration

How to control sub_page_configs_update ↓

AI agents use sub_page_configs_update 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

The tool creates or modifies data reversibly by updating subscription page configurations. This is a Write operation—not destructive (data can be reverted), not read-only, and not inherently dangerous without additional context about what configuration changes entail.

From the tool's definition Tool name contains 'update' and description states 'Update a subscription page configuration'. This modifies configuration data within the VPN panel system.

Documented attack patterns abuse exactly the kind of access sub_page_configs_update 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 sub_page_configs_update:

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

sub_page_configs_update 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.
