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

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

## Why entity_create_circle is rated Medium

Creating a circle entity in a CAD drawing is a reversible Write operation—it adds new geometry that can be edited or deleted. The severity is medium because misuse by an AI agent could create unwanted geometric clutter or confusion in production CAD files, but the operation is not destructive (not irreversible) and does not execute arbitrary code or move money.

From the tool's own definition: "Tool name 'entity_create_circle' indicates creation of a geometric entity (circle) in an AutoCAD drawing. The server description states the tool set includes 'drawing creation' and 'entity modification' capabilities."

## Use case

AI agents use entity_create_circle 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
{
  "version": "1",
  "default": "deny",
  "tools": {
    "entity_create_circle": {
      "limits": [
        {

          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
