AI agents invoke macro_export_vba to trigger actions in SolidWorks MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.
Exporting a macro to VBA code produces executable script artifacts that can subsequently be run to perform arbitrary operations within SolidWorks. While the export step itself may be more of a Write action (producing a file), the primary risk is that it enables code execution workflows and the output is executable code.
From the tool's definition 'Export a recorded macro to VBA code' — exports executable VBA macro code from SolidWorks
Documented attack patterns abuse exactly the kind of access macro_export_vba gives an agent:
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 macro_export_vba:
{
"version": "1",
"default": "deny",
"tools": {
"macro_export_vba": {
"limits": [
{
"counter": "macro_export_vba_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
} macro_export_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.
Free to start. No card required.
Export a recorded macro to VBA code. 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.
Register the SolidWorks MCP Server MCP server in PolicyLayer and add a rule for macro_export_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.
macro_export_vba is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the macro_export_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.
Set action: deny in the PolicyLayer policy for macro_export_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.
macro_export_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.
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.
Free to start. No card required.
