Generate 3D HTML viewer of model geometry. Use this instead of
AI agents call view_model 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.
This tool retrieves and displays existing model geometry data in a 3D viewer format. It performs no side effects, does not modify data, execute code, delete anything, or involve financial operations. It is purely a read operation for viewing building energy simulation model data.
From the tool's definition Tool name 'view_model' and description 'Generate 3D HTML viewer of model geometry' indicate a visualization/querying function with no modification, deletion, or execution of external operations.
Documented attack patterns abuse exactly the kind of access view_model 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_model:
{
"version": "1",
"default": "deny",
"tools": {
"view_model": {}
}
}view_model is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Generate 3D HTML viewer of model geometry. Use this instead of. 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_model: 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_model 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_model 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_model. 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_model 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.
