## Facts

- Tool: `export_ifc`
- 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": "export_ifc",
    "arguments": {}
  }
}
```

## Why export_ifc is rated Medium

The tool exports architectural/BIM data from Revit to IFC format, creating a new file or overwriting an existing export. This is a Write operation (creates/exports data) rather than Read (it produces persistent output). Severity is high because exported IFC files could be shared externally, potentially exposing sensitive building information or design details, and incorrect exports could affect downstream workflows.

From the tool's own definition: "Tool name is 'export_ifc', which exports model data to IFC (Industry Foundation Classes) format. This is a write/output operation that serializes and exports building model data to an external file."

## Use case

AI agents use export_ifc 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": {
    "export_ifc": {
      "limits": [
        {
          "counter": "export_ifc_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}
```
