edit_macro · Solidworks MCP: Risk & Policy

WHAT IT DOES

What edit_macro does on Solidworks

AI agents invoke edit_macro 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 edit_macro needs a policy

Opening a macro in the VBA editor is a precursor to executing arbitrary VBA code within SolidWorks. Even if the tool itself only 'opens' the editor, it enables code execution in the SolidWorks environment. VBA macros can perform destructive, system-level, or arbitrary operations, making this an Execute-category tool with high severity.

From the tool's definition 'Open a macro in the SolidWorks VBA editor' — the tool interacts with the VBA macro editor, which is used to run/edit executable code within SolidWorks

Verdict

edit_macro Rate-limited

edit_macro 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.

What risk level is edit_macro? +

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

Can I rate-limit edit_macro? +

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