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

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

## Why set_viewport_properties is rated Medium

This tool creates or modifies viewport properties reversibly within an AutoCAD drawing context. While it changes drawing state, the modification is non-destructive and can be undone. It does not execute arbitrary code, delete data, or trigger financial operations, making Write the appropriate classification rather than Execute or Destructive.

From the tool's own definition: "'set_viewport_properties' modifies viewport properties in AutoCAD drawing space. The description states '设置图纸空间视口的属性' (set the properties of drawing space viewport), indicating modification of existing viewport configuration rather than deletion or code…"

## Use case

AI agents use set_viewport_properties 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.
