AI agents call extract_summary_metrics to retrieve information from Openstudio without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool appears designed to retrieve or aggregate summary metrics from building energy simulation models or results. No description provided, lowering confidence slightly, but the naming pattern and server purpose (querying and analyzing results) strongly indicate a Read operation with no side effects. Blast radius if misused is minimal—worst case an agent extracts irrelevant or unnecessary data.
From the tool's definition Tool name 'extract_summary_metrics' combined with server context indicating OpenStudio energy simulation analysis. The verb 'extract' and noun 'metrics' suggest data retrieval.
Documented attack patterns abuse exactly the kind of access extract_summary_metrics gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Openstudio, and nothing reaches the server without passing your rules. This is the rule we recommend for extract_summary_metrics:
{
"version": "1",
"default": "deny",
"tools": {
"extract_summary_metrics": {}
}
}extract_summary_metrics is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

extract_summary_metrics. It is categorised as a Read tool in the Openstudio MCP Server, which means it retrieves data without modifying state.
Register the Openstudio MCP server in PolicyLayer and add a rule for extract_summary_metrics: 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 Openstudio. Nothing to install.
extract_summary_metrics 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 extract_summary_metrics 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 extract_summary_metrics. 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.
extract_summary_metrics is provided by the Openstudio MCP server (natlabrockies/openstudio-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Openstudio, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
