Why alert_me needs a policy

The description is empty, so the exact behavior cannot be determined. Based on the tool name 'alert_me' and the server context (voice calls, tiered alerts), it likely triggers some kind of alert or notification to the user via phone call. This could be an Execute-level action (triggering an external phone call), but without a description, confidence is low.

From the tool's definition Tool name is 'alert_me' but description is empty or uninformative.

POLICY

How to control alert_me

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "alert_me": {
      "limits": [
        {
          "counter": "alert_me_rate",
          "window": "minute",
          "max": 60,
          "scope": "grant"
        }
      ]
    }
  }
}

alert_me gets a rate cap, and everything else on the server is denied unless you say otherwise.

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