Why diagnose_permissions needs a policy

This tool reads and analyzes permission settings for the current connection to provide diagnostic information. It retrieves data without modifying any state, making it a Read operation. Severity is low as it only exposes permission configuration details.

POLICY

How to control diagnose_permissions

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 diagnose_permissions:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "diagnose_permissions": {}
  }
}

diagnose_permissions is read-only, so it stays allowed — but 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.
