## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "entity_create_polyline",
    "arguments": {}
  }
}
```

## Why entity_create_polyline is rated Medium

This tool creates new drawing entities (polylines) in the CAD document, which is a reversible modification. It does not execute arbitrary code, delete data, or trigger financial operations. While creation of CAD entities could have downstream effects if the drawing is published or used in manufacturing/construction, the tool itself is a standard Write operation that adds data to the model.

From the tool's own definition: "Tool name 'entity_create_polyline' and description 'Create a lightweight 2D polyline through the given points' explicitly performs a creation operation that modifies the CAD drawing by adding a new geometric entity."

## Use case

AI agents use entity_create_polyline to create or update resources in AutoCAD MCP Pro, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your AutoCAD MCP Pro environment.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches AutoCAD MCP Pro:

```json
