THE RISK

Medium Risk

Why sketch_circular_pattern needs a policy

This tool creates a circular pattern within a sketch, which is a standard CAD modeling operation that modifies the sketch (Write category). The effect is reversible via undo/redo in SolidWorks. Severity is medium because misuse could corrupt a design file or require rework, but the impact is limited to the current document and does not affect external systems or data persistence beyond the active model.

From the tool's definition Tool name 'sketch_circular_pattern' and description 'Create a circular pattern of sketch entities' indicate creation/modification of sketch geometry.

POLICY

How to control sketch_circular_pattern

PolicyLayer is an MCP gateway — it sits between your AI agents and SolidWorks MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for sketch_circular_pattern:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "sketch_circular_pattern": {
      "limits": [
        {
          "counter": "sketch_circular_pattern_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

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.

Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

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 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 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 MCP Server. 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 MCP server (jianzhichun/solidworks-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every SolidWorks MCP Server tool call.

Start from SolidWorks MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
