Graded by PlugVetRubric v2

Not a guarantee. A hygiene check of the source at the commit shown, not a security audit.

INSTALL_UNPINNED NETWORK_NO_FIXED_HOST NETWORK_UNNAMED_HOST SECRETS_PATH_DOTENV INSTALL_DOCUMENTED_INSTALLER SECRETS_ENV_READ

Why this grade

  • INSTALL_UNPINNED Low

    Dependencies use a range or git URL with no lockfile.

    README.md, line 134 curl -sSL https://raw.githubusercontent.com/HaiNick/Shark-no-Kari/main/scripts/setup-vps.sh | bash

  • NETWORK_NO_FIXED_HOST Low

    Makes a network call whose host is not written as a fixed address.

    scripts/setup-vps.sh, line 10 curl -fsSL https://download.docker.com/linux/ubuntu/gpg -o /etc/apt/keyrings/docker.asc

  • NETWORK_UNNAMED_HOST Low

    Calls a fixed host that the description does not name.

    scripts/setup-vps.sh, line 10 curl -fsSL https://download.docker.com/linux/ubuntu/gpg -o /etc/apt/keyrings/docker.asc

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    scripts/setup-vps.sh, line 30 echo " 2. cp .env.example .env"

  • INSTALL_DOCUMENTED_INSTALLER Note

    Documentation shows an installer that pipes a download into a shell.

    README.md, line 134 curl -sSL https://raw.githubusercontent.com/HaiNick/Shark-no-Kari/main/scripts/setup-vps.sh | bash

  • SECRETS_ENV_READ Note

    Reads an environment variable whose name contains KEY, SECRET, TOKEN, PASSWORD or CREDENTIAL.

    src/server.py, line 27 API_KEY = os.getenv("MCP_API_KEY", "")

Any High, or two or more Medium findings, give D. One Medium gives C. Low findings or a security Note give B. Each code names a finding behind the letter.

Grades are a hygiene check of the source at the commit shown, on the date checked, not a security audit or a guarantee. The free directory grades are automated. Before release, a PlugVet engineer reviews every paid report and any grade we hold back, including all F grades, against the source code and the evidence we quote.

What was checked

Plain notes from the hygiene checks.

  • Permissions

    Pass

    No shell or command execution found, and no extra permission was declared.

  • Install and update

    Concern

  • Network

    Concern
