vba_sheet_metal · Solidworks MCP: Risk & Policy

WHAT IT DOES

What vba_sheet_metal does on Solidworks

AI agents invoke vba_sheet_metal to trigger actions in Solidworks. 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.

WHY IT NEEDS A POLICY

Why vba_sheet_metal needs a policy

VBA generation implies code execution within SolidWorks. Executing VBA macros can trigger arbitrary CAD operations, modify models, or invoke system-level commands. Even if the tool only generates (rather than runs) the code, VBA for sheet metal operations can irreversibly alter CAD models, making this at minimum an Execute-level risk.

Verdict

vba_sheet_metal Rate-limited

vba_sheet_metal 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.
