Remove boiler, chiller, or other equipment from a plant loop's supply side.
AI agents call remove_supply_equipment to permanently remove resources in Openstudio — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently removes equipment from an energy simulation model. Once deleted, the equipment configuration cannot be restored without re-adding components manually. This is an irreversible modification that alters the model state and could cause downstream simulation failures or incorrect analysis results.
From the tool's definition Tool name 'remove_supply_equipment' and description 'Remove boiler, chiller, or other equipment from a plant loop's supply side' indicate irreversible deletion of model components.
Documented attack patterns abuse exactly the kind of access remove_supply_equipment 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 remove_supply_equipment:
{
"version": "1",
"default": "deny",
"hide": [
"remove_supply_equipment"
]
}remove_supply_equipment disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Remove boiler, chiller, or other equipment from a plant loop's supply side. It is categorised as a Destructive tool in the Openstudio MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Openstudio MCP server in PolicyLayer and add a rule for remove_supply_equipment: 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.
remove_supply_equipment is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the remove_supply_equipment 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 remove_supply_equipment. 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.
remove_supply_equipment 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.
