Why dimension_linear needs a policy

Based on the tool name and server context, 'dimension_linear' likely creates a linear dimension annotation in a CAD drawing. This is a Write operation (creating/adding an entity to the drawing). Confidence is lowered due to the empty description providing no direct confirmation.

From the tool's definition Tool name 'dimension_linear' on an AutoCAD automation server; description is empty and uninformative.

POLICY

How to control dimension_linear

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

policy.json

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

dimension_linear 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.

Create a free account and register AutoCAD MCP Pro — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about dimension_linear

What does the dimension_linear tool do? +

dimension_linear. It is categorised as a Write tool in the AutoCAD MCP Pro MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on dimension_linear? +

Register the AutoCAD MCP Pro MCP server in PolicyLayer and add a rule for dimension_linear: 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 AutoCAD MCP Pro. Nothing to install.

What risk level is dimension_linear? +

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

Can I rate-limit dimension_linear? +

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

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

dimension_linear is provided by the AutoCAD MCP Pro MCP server (u-c4n/autocad-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every AutoCAD MCP Pro tool call.

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