set_drawing_scale · Solidworks MCP: Risk & Policy

WHAT IT DOES

What set_drawing_scale does on Solidworks

AI agents use set_drawing_scale 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 set_drawing_scale needs a policy

The tool modifies drawing scale properties, which is a reversible configuration change to design artifacts. It does not delete data (not Destructive), execute arbitrary code (not Execute), trigger financial transactions (not Financial), or merely retrieve data (not Read). Scale changes can be undone by setting a different scale value, making this a Write operation.

From the tool's definition Tool description states 'Set the scale of the drawing sheet or a specific view' — this modifies drawing properties in a reversible manner.

Verdict

set_drawing_scale Rate-limited

set_drawing_scale stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

Questions about set_drawing_scale

What does the set_drawing_scale tool do? +

Set the scale of the drawing sheet or a specific view. 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 set_drawing_scale? +

Register the Solidworks MCP server in PolicyLayer and add a rule for set_drawing_scale: 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 set_drawing_scale? +

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

Can I rate-limit set_drawing_scale? +

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

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