sketch_circular_pattern · Solidworks MCP: Risk & Policy

WHAT IT DOES

What sketch_circular_pattern does on Solidworks

AI agents use sketch_circular_pattern 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 sketch_circular_pattern needs a policy

This tool modifies a sketch by adding a pattern, which is a reversible design change. It does not delete data (Destructive), execute arbitrary code (Execute), involve financial transactions (Financial), or merely retrieve data (Read). It fits the Write category as it creates new geometry in a sketch that can be undone or modified.

From the tool's definition Tool name 'sketch_circular_pattern' and description 'Create a circular pattern of sketch entities' indicate the tool creates/modifies sketch geometry. The verb 'Create' denotes a reversible write operation within a CAD sketch.

Verdict

sketch_circular_pattern Rate-limited

sketch_circular_pattern 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 sketch_circular_pattern

What does the sketch_circular_pattern tool do? +

Create a circular pattern of sketch entities. 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 sketch_circular_pattern? +

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

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

Can I rate-limit sketch_circular_pattern? +

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

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

sketch_circular_pattern 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.
