sw_export · Solidworks MCP: Risk & Policy

WHAT IT DOES

What sw_export does on Solidworks

AI agents use sw_export 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 sw_export needs a policy

The sw_export tool creates new files in standardized formats (STEP, IGES, STL) from a SolidWorks document. This is a Write operation as it produces new data artifacts that persist on the system, though the operation is reversible (exported files can be deleted). It is not Destructive because the original document remains unchanged.

From the tool's definition Tool description states 'export current document as STEP / IGES / STL format', indicating file creation/output operations. The tool creates new files in standard CAD exchange formats.

Verdict

sw_export Rate-limited

sw_export 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.

PolicyLayer is an MCP gateway: every tool call is checked against your rule before it reaches Solidworks, so you can run agents against it safely.

FAQ

Questions about sw_export

What does the sw_export tool do? +

将当前文档导出为 STEP / IGES / STL 格式。. 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 sw_export? +

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

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

Can I rate-limit sw_export? +

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

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

sw_export is provided by the Solidworks MCP server (yimu0824/solidworks-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
