RECOMMENDED RULE

The rule that runs list_category_parameters safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Revit MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For list_category_parameters, this is the rule to start with:

list_category_parameters Allowed

list_category_parameters is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

{
  "version": "1",
  "default": "deny",
  "tools": {
    "list_category_parameters": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Revit MCP Server, apply this rule, and every list_category_parameters call is checked against it from then on.
