Watch out for

• It can run raw AutoCAD commands and LISP

  A blocklist of 36 commands stops the obvious cases, but the README says it is not a security boundary. Never turn on DANGEROUS_COMMANDS_ENABLED. github.com

• File access is open until you set ALLOWED_PATHS

  With ALLOWED_PATHS empty, it can open and save files almost anywhere your user account can. Set it to your drawings folder. github.com

• It edits the drawing you have open

  In live mode it draws, erases and saves inside your running AutoCAD. Work on a copy until you trust the results. github.com

• Remote HTTP access needs a token

  HTTP mode only listens on your own computer. Opening it to the network needs ALLOW_REMOTE_HTTP and a bearer token. github.com
