Why maker_unlock_idle needs a policy

This tool triggers a session state change (unlocking an idle-locked session) on an external system. It is not a simple read, nor does it delete data, but it does execute an administrative action that changes system state. The 'Admin-only' designation indicates elevated privilege and potential for misuse if invoked without authorization.

From the tool's definition Clear an idle-locked session without ending it. Admin-only.

POLICY

How to control maker_unlock_idle

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 maker_unlock_idle:

policy.json

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

maker_unlock_idle 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.
