Why vba_assembly_components needs a policy

Generating VBA code that runs through a COM bridge to insert and manage assembly components constitutes code execution with potentially wide-ranging effects on the SolidWorks model. Misuse could corrupt assemblies or insert malicious/unintended components.

From the tool's definition 'Generate VBA for inserting and managing components' — generates and presumably executes VBA code that inserts and manages assembly components in SolidWorks via a COM bridge

POLICY

How to control vba_assembly_components

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_assembly_components:

policy.json

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

vba_assembly_components 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_assembly_components

What does the vba_assembly_components tool do? +

Generate VBA for inserting and managing components. 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_assembly_components? +

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

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

Can I rate-limit vba_assembly_components? +

Yes. Add a rate_limit block to the vba_assembly_components 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_assembly_components completely? +

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

vba_assembly_components 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.
