AI agents call list_electric_equipment to retrieve information from OpenStudio MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or enumerates electric equipment definitions from an OSM file without modifying any data. It aligns with the 'list' and 'get' read-only operations already established in the server's tool suite. No side effects, data modification, execution, destruction, or financial impact is indicated.

PolicyLayer is an MCP gateway — it sits between your AI agents and OpenStudio MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for list_electric_equipment:
{
"version": "1",
"default": "deny",
"tools": {
"list_electric_equipment": {}
}
}list_electric_equipment is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

list_electric_equipment is provided by the OpenStudio MCP Server MCP server (roruizf/openstudio-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from OpenStudio MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
