stop_frida_server

THE RISK

High Risk

Stopping a frida-server is an operational action that disrupts a running service on the device. While not destructive in the data-loss sense and not irreversible (the server can be restarted), it is an execute-class action that triggers external effects on the device infrastructure. It disables dynamic instrumentation capabilities and could interrupt ongoing analyses.

From the tool's definition Tool description states it stops frida-server on a device ('停止设备上的 frida-server' translates to 'stop frida-server on the device'). This terminates a running system service/daemon.

HOW TO CONTROL STOP_FRIDA_SERVER

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

policy.json

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

stop_frida_server 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 Frida — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
