THE RISK

High Risk

Why create_feature_vba needs a policy

This tool generates VBA code for SolidWorks, which constitutes executing arbitrary code via the COM bridge. VBA execution can perform a wide range of operations including file system access, model modifications, and external operations. The blast radius is high because misused VBA can irreversibly alter CAD models, access system resources, or trigger unintended operations in SolidWorks.

From the tool's definition Generate VBA code to create a specific feature — generates and presumably executes VBA code within SolidWorks

POLICY

How to control create_feature_vba

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 create_feature_vba:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "create_feature_vba": {
      "limits": [
        {
          "counter": "create_feature_vba_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

create_feature_vba stays usable, but rate-capped — a runaway agent can't fire it dozens of times 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 create_feature_vba

What does the create_feature_vba tool do? +

Generate VBA code to create a specific feature. It is categorised as a Execute tool in the SolidWorks MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on create_feature_vba? +

Register the SolidWorks MCP Server MCP server in PolicyLayer and add a rule for create_feature_vba: 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 create_feature_vba? +

create_feature_vba is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit create_feature_vba? +

Yes. Add a rate_limit block to the create_feature_vba 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 create_feature_vba completely? +

Set action: deny in the PolicyLayer policy for create_feature_vba. 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 create_feature_vba? +

create_feature_vba 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.
