## Facts

- Tool: `create_room_separation`
- Server: Revit MCP Server (`demolinator/revit-mcp-server`) — https://policylayer.com/tools/demolinator-revit-mcp-server.md
- Homepage: https://github.com/Demolinator/revit-mcp-server
- Risk category: Write (Medium risk)
- Registry record: grade F, identity unverified
- Server rate-limited: no
- Parameters: 0
- Recommended policy verdict: Rate-limited

## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "create_room_separation",
    "arguments": {}
  }
}
```

## Why create_room_separation is rated Medium

The tool creates new model elements (room separations) in a Revit project, which is a reversible modification operation. This is Write rather than Execute because it performs a specific creation action with predictable effects, not arbitrary code execution. The empty description lowers confidence slightly, but the naming pattern and sibling context strongly indicate element creation.

From the tool's own definition: "Tool name 'create_room_separation' indicates creation of architectural elements in Revit (room separation lines/boundaries)."

## Use case

AI agents use create_room_separation to create or update resources in Revit MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Revit MCP Server environment.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Revit MCP Server:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "create_room_separation": {
      "limits": [
        {
          "counter": "create_room_separation_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
