THE RISK

Medium Risk

Why create_server_group needs a policy

This tool creates (adds) a new organizational structure in the TeamSpeak server but does not execute arbitrary code, delete data irreversibly, or move funds. The action is reversible by deleting the group. The blast radius is moderate: an AI could misconfigure permissions or create confusing group hierarchies, but the primary impact is configuration drift rather than data loss or unauthorized execution.

From the tool's definition Tool creates a new server group with specified name and type—a reversible modification of server configuration state.

POLICY

How to control create_server_group

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "create_server_group": {
      "limits": [
        {
          "counter": "create_server_group_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

create_server_group 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.

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

Enforce policy on every TeamSpeak MCP tool call.

Start from TeamSpeak MCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
