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

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

## Why fillet_entities is rated Medium

Filleting is a reversible geometric modification operation that alters existing entities in the drawing. It is not destructive (data remains, operation can be undone), not Execute (no arbitrary code execution), and not Read (produces side effects). This fits Write category as it creates or modifies drawing data reversibly.

From the tool's own definition: "Tool name 'fillet_entities' and description indicating it performs fillet operations (圆角倒角 = rounding/chamfering) on entities using arcs with specified radius. This modifies CAD drawing geometry."

## Use case

AI agents use fillet_entities 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": {
