WHAT IT DOES

What create_initialized_macro does on Solidworks

AI agents use create_initialized_macro to create or update resources in Solidworks — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Solidworks environment.

WHY IT NEEDS A POLICY

Why create_initialized_macro needs a policy

This tool creates new macro files with VBA initialization in SolidWorks. While it writes/creates reversible artifacts (macros can be deleted), the severity is elevated to medium because: (1) macros execute code within SolidWorks with design/manufacturing implications, (2) if an agent generates malicious or poorly-formed VBA, it could corrupt designs or crash the CAD session, (3) however, the macro itself is a…

From the tool's definition Tool name 'create_initialized_macro' and description 'Create a new macro' indicates creation of new code/script artifacts. The initialization suggests setup of executable content within SolidWorks.

FAQ

Questions about create_initialized_macro

What does the create_initialized_macro tool do? +

Create a new macro with proper SolidWorks VBA initialization. It is categorised as a Write tool in the Solidworks MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on create_initialized_macro? +

Register the Solidworks MCP server in PolicyLayer and add a rule for create_initialized_macro: 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. Nothing to install.

What risk level is create_initialized_macro? +

create_initialized_macro is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit create_initialized_macro? +

Yes. Add a rate_limit block to the create_initialized_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 create_initialized_macro completely? +

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

create_initialized_macro is provided by the Solidworks MCP server (solidworks-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
