Get the current state of a smart home device.
AI agents call get_device_state to retrieve information from MCP Personal Assistant Agent without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only queries and retrieves data about smart home device states with no side effects, modifications, or external operations triggered. It falls squarely into the Read category.
From the tool's definition Tool name 'get_device_state' and description 'Get the current state of a smart home device' indicate a read-only operation that retrieves information about device status without modifying or controlling anything.
Documented attack patterns abuse exactly the kind of access get_device_state gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and MCP Personal Assistant Agent, and nothing reaches the server without passing your rules. This is the rule we recommend for get_device_state:
{
"version": "1",
"default": "deny",
"tools": {
"get_device_state": {}
}
}get_device_state is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get the current state of a smart home device. It is categorised as a Read tool in the MCP Personal Assistant Agent MCP Server, which means it retrieves data without modifying state.
Register the MCP Personal Assistant Agent MCP server in PolicyLayer and add a rule for get_device_state: 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 MCP Personal Assistant Agent. Nothing to install.
get_device_state is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_device_state 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 get_device_state. 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.
get_device_state is provided by the MCP Personal Assistant Agent MCP server (zhangzhongnan928/mcp-pa-ai-agent). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from MCP Personal Assistant Agent, 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.
