AI agents invoke reboot_device to trigger actions in Adb. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.
Rebooting a device is an external operation that disrupts all running processes, sessions, and services on the Android device. It is not purely destructive (no data loss) but executes a significant system-level operation with broad impact. Misuse by an AI agent could interrupt active operations, testing sessions, or critical processes on the device.
From the tool's definition Tool name 'reboot_device' and description '重启设备' (reboot device) — triggers a full device reboot via ADB
Documented attack patterns abuse exactly the kind of access reboot_device gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Adb, and nothing reaches the server without passing your rules. This is the rule we recommend for reboot_device:
{
"version": "1",
"default": "deny",
"tools": {
"reboot_device": {
"limits": [
{
"counter": "reboot_device_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}reboot_device 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.
Free to start. No card required.
重启设备. It is categorised as a Execute tool in the Adb MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Adb MCP server in PolicyLayer and add a rule for reboot_device: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Adb. Nothing to install.
reboot_device is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the reboot_device rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for reboot_device. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
reboot_device is provided by the Adb MCP server (wolfcoming/adb_mcp_server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Adb, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
