THE RISK

Medium Risk

Why export_file needs a policy

Exporting a model creates new files on the filesystem in a specified format. This is a Write operation (creating new data/files) rather than Destructive (does not delete or overwrite existing model data) or Execute (does not run code or commands). Misuse could result in unintended file creation or data leakage, hence medium severity.

POLICY

How to control export_file

PolicyLayer is an MCP gateway — it sits between your AI agents and SolidWorks MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for export_file:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "export_file": {
      "limits": [
        {
          "counter": "export_file_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

export_file stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

Create a free account and register SolidWorks MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about export_file

What does the export_file tool do? +

Export the current model to various formats. It is categorised as a Write tool in the SolidWorks MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on export_file? +

Register the SolidWorks MCP Server MCP server in PolicyLayer and add a rule for export_file: 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 SolidWorks MCP Server. Nothing to install.

What risk level is export_file? +

export_file is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit export_file? +

Yes. Add a rate_limit block to the export_file 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.

How do I block export_file completely? +

Set action: deny in the PolicyLayer policy for export_file. 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.

What MCP server provides export_file? +

export_file is provided by the SolidWorks MCP Server MCP server (jianzhichun/solidworks-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every SolidWorks MCP Server tool call.

Start from SolidWorks MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
