Why vba_error_handling needs a policy

VBA generation implies code execution within the SolidWorks COM environment. Generated VBA can perform arbitrary operations including modifying models, deleting features, or triggering external processes. The 'comprehensive error handling and logging' framing suggests the output is intended to run, not merely be displayed.

From the tool's definition Generate VBA with comprehensive error handling and logging — generates and presumably executes VBA (Visual Basic for Applications) code within SolidWorks

Documented attack patterns abuse exactly the kind of access vba_error_handling gives an agent:

POLICY

How to control vba_error_handling

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 vba_error_handling:

policy.json

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

vba_error_handling 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 vba_error_handling

What does the vba_error_handling tool do? +

Generate VBA with comprehensive error handling and logging. 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 vba_error_handling? +

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

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

Can I rate-limit vba_error_handling? +

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

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

vba_error_handling 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.
