How to control wait_for_any_of

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

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "wait_for_any_of": {
      "limits": [
        {
          "counter": "wait_for_any_of_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

wait_for_any_of 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.
