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

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

## Why array_polar is rated Medium

The tool creates or duplicates CAD entities, which is a reversible modification operation. It does not execute arbitrary code, delete data irreversibly, or involve financial transactions. While it modifies the drawing state, array operations are standard CAD modifications that can be undone.

From the tool's own definition: "Tool name 'array_polar' and description indicate it performs a polar array operation that '围绕中心点环形复制实体' (circularly duplicates entities around a center point). This creates new geometric elements in the drawing."

## Use case

AI agents use array_polar to create or update resources in Pypi:best Cad, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Pypi:best Cad environment.

## Recommended policy (PolicyLayer)

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

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "array_polar": {
      "limits": [
        {
          "counter": "array_polar_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
