add_diameter_dimension · Solidworks MCP: Risk & Policy

WHAT IT DOES

What add_diameter_dimension does on Solidworks

AI agents use add_diameter_dimension 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 add_diameter_dimension needs a policy

This tool adds metadata (dimensions) to an existing drawing view, which is a reversible modification. It does not delete data (Destructive), execute arbitrary code (Execute), trigger financial transactions (Financial), or merely read data (Read). The moderate severity reflects that incorrect dimensions could propagate through design workflows, but the change is reversible and typically requires intentional use.

From the tool's definition Tool name 'add_diameter_dimension' and description 'Add dimension with diameter symbol to a view' indicate the tool creates/modifies dimensional annotations on a SolidWorks drawing.

Verdict

add_diameter_dimension Rate-limited

add_diameter_dimension 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.

FAQ

Questions about add_diameter_dimension

What does the add_diameter_dimension tool do? +

Add dimension with diameter symbol to a 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 add_diameter_dimension? +

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

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

Can I rate-limit add_diameter_dimension? +

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

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

add_diameter_dimension 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.
