THE RISK

Why view_zoom_and_screenshot needs a policy

This tool performs viewport manipulation (zoom) and screenshot capture—both read-only operations that retrieve visual data without modifying drawings, entities, or CAD documents. No entities are created, deleted, or altered. The zoom operation is a temporary view state change that does not persist as document changes. Screenshot capture is pure data retrieval.

From the tool's definition Tool name 'view_zoom_and_screenshot' and description 'Zoom to extents (or window if coordinates given), then capture a screenshot' indicate view navigation and image capture operations only.

POLICY

How to control view_zoom_and_screenshot

PolicyLayer is an MCP gateway — it sits between your AI agents and AutoCAD MCP Pro, and nothing reaches the server without passing your rules. This is the rule we recommend for view_zoom_and_screenshot:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "view_zoom_and_screenshot": {}
  }
}

view_zoom_and_screenshot is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register AutoCAD MCP Pro — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
