WHAT IT DOES

What ground_vlm_region does on Pypi:best Cad

RISK

Why ground_vlm_region is rated Low

This tool appears to query/map pixel bounding box coordinates from a visual language model (VLM) to AutoCAD entity handles using a snapshot. It retrieves/resolves identifiers without modifying any drawing data. No creation, modification, deletion, or execution of commands is implied — it is a lookup/read operation.

RECOMMENDED RULE

The rule that runs ground_vlm_region safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Pypi:best Cad, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For ground_vlm_region, this is the rule to start with:

ground_vlm_region Allowed

ground_vlm_region is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
