Get zone temperature by averaging applicable devices measure_temperature in the zone
AI agents call get_zone_temp to retrieve information from HomeyPro MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only operation: it retrieves temperature measurements from devices and computes an average. There are no side effects, no data modification, no code execution, and no destructive operations. The minimal blast radius (reporting incorrect temperature data) presents only low severity risk.
From the tool's definition Tool name 'get_zone_temp' and description 'Get zone temperature by averaging applicable devices measure_temperature in the zone' indicate a retrieval operation that queries and aggregates temperature data without modifying, deleting, or executing external…
Documented attack patterns abuse exactly the kind of access get_zone_temp gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and HomeyPro MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_zone_temp:
{
"version": "1",
"default": "deny",
"tools": {
"get_zone_temp": {}
}
}get_zone_temp is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get zone temperature by averaging applicable devices measure_temperature in the zone. It is categorised as a Read tool in the HomeyPro MCP Server MCP Server, which means it retrieves data without modifying state.
Register the HomeyPro MCP Server MCP server in PolicyLayer and add a rule for get_zone_temp: 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 HomeyPro MCP Server. Nothing to install.
get_zone_temp 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_zone_temp 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_zone_temp. 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_zone_temp is provided by the HomeyPro MCP Server MCP server (pigmej/python-homey-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from HomeyPro MCP Server, 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.
