Draw a rectangle in the active sketch. AUTOMATIC: This tool automatically ensures an active sketch context before drawing. The rectangle can be created as construction geometry or centered at a point if needed.
AI agents use sketch_rectangle to create or update resources in SolidWorks MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your SolidWorks MCP Server environment.
This tool creates new sketch geometry (a rectangle) in an active SolidWorks sketch. It is a write/create operation with no irreversible destructive effects, no code execution, and no financial implications. Misuse has low blast radius as it only adds geometry to a sketch that can be deleted or undone.
From the tool's definition 'Draw a rectangle in the active sketch' - creates geometry within a SolidWorks sketch context
Documented attack patterns abuse exactly the kind of access sketch_rectangle gives an agent:
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_rectangle:
{
"version": "1",
"default": "deny",
"tools": {
"sketch_rectangle": {
"limits": [
{
"counter": "sketch_rectangle_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}sketch_rectangle 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.

Draw a rectangle in the active sketch. AUTOMATIC: This tool automatically ensures an active sketch context before drawing. The rectangle can be created as construction geometry or centered at a point if needed. 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.
Register the SolidWorks MCP Server MCP server in PolicyLayer and add a rule for sketch_rectangle: 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.
sketch_rectangle is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the sketch_rectangle 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.
Set action: deny in the PolicyLayer policy for sketch_rectangle. 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.
sketch_rectangle 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.
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.
