Why adguard_toggle_protection needs a policy

This tool triggers an external operation that changes the runtime state of a DNS filtering service. Disabling it removes all DNS-level protections for all clients, which is a significant security impact.

From the tool's definition 'Enable or disable AdGuard Home protection. Disabling stops ALL DNS filtering until re-enabled — clients will resolve via upstream with no blocking.'

How to control adguard_toggle_protection

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "adguard_toggle_protection": {
      "limits": [
        {
          "counter": "adguard_toggle_protection_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

adguard_toggle_protection stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

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