Watch out for

• It acts with your own account's permissions

  Every tool call carries your token, so the assistant can only see and do what your Nightingale account can. github.com

• Writes are off until an admin turns them on

  By default every client only gets read tools. Enabling writes exposes about 32 create, update and toggle tools, including users, roles, password resets and data sources, with no per-call approval on the server. github.com
