AI agents call view_simulation_data 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 name strongly indicates viewing or querying simulation results without modification. No description provided limits confidence slightly, but in context of an energy simulation system, viewing data is a read-only operation with minimal risk if misused by an agent.
From the tool's definition Tool name 'view_simulation_data' indicates data retrieval; lacks description but follows pattern of sibling tools that create/modify models (add_* operations) suggesting this one reads results.
Documented attack patterns abuse exactly the kind of access view_simulation_data 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 view_simulation_data:
{
"version": "1",
"default": "deny",
"tools": {
"view_simulation_data": {}
}
}view_simulation_data is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

view_simulation_data. 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 view_simulation_data: 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.
view_simulation_data 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 view_simulation_data 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 view_simulation_data. 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.
view_simulation_data 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.
