AI agents use add_sketch_dimension 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 or modifies dimension annotations on sketch entities in SolidWorks. While dimensions can be edited or deleted, the primary action is additive/constructive and reversible—they can be removed without permanent data loss. This places it in Write rather than Destructive.
From the tool's definition Tool name 'add_sketch_dimension' and description 'Add dimensions to sketch entities' indicates creation/modification of sketch geometry. The note about 'automatically ensures an active sketch context' confirms it modifies the sketch state.
Documented attack patterns abuse exactly the kind of access add_sketch_dimension 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 add_sketch_dimension:
{
"version": "1",
"default": "deny",
"tools": {
"add_sketch_dimension": {
"limits": [
{
"counter": "add_sketch_dimension_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}add_sketch_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.

Add dimensions to sketch entities. IMPORTANT: This tool automatically ensures an active sketch context before adding dimensions. The entity parameter must be a full SolidWorks entity name like. 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 add_sketch_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 MCP Server. Nothing to install.
add_sketch_dimension 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 add_sketch_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.
Set action: deny in the PolicyLayer policy for add_sketch_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.
add_sketch_dimension 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.
