Reads what is published about the server: package advisories, licence, secrets in the documented setup and tool permissions. Nothing is installed or run, so this is not a security assessment. Checked by edna-static-v1. What it checks

  • Medium The repository has no licence file, so nobody has been granted the right to use, copy or change the code.
  • Note No published npm or PyPI package of this repository was found, so package advisories were not checked.
  • Note The lab has not recorded this server's tool list yet, so tool permissions were not checked.
