Press the power button (lock/wake).
AI agents invoke press_power to trigger actions in Vphone. 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.
This tool emulates a hardware key press (power button) that triggers an external operation on a virtual iOS device — locking or waking it. It's an action with side effects (state change of the device) but not destructive, financial, or a simple data read/write. It falls under Execute as it triggers a real device interaction.

Documented attack patterns abuse exactly the kind of access press_power gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Vphone, and nothing reaches the server without passing your rules. This is the rule we recommend for press_power:
{
"version": "1",
"default": "deny",
"tools": {
"press_power": {
"limits": [
{
"counter": "press_power_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}press_power 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.
Press the power button (lock/wake). It is categorised as a Execute tool in the Vphone MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Vphone MCP server in PolicyLayer and add a rule for press_power: 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 Vphone. Nothing to install.
press_power 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 press_power 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 press_power. 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.
press_power is provided by the Vphone MCP server (pluginslab/vphone-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Vphone, 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.
