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

Rescanned at commit 31b2c4b5b578, unchanged since the check below.

INSTALL_UNPINNED NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV PERMISSION_SHELL_DECLARED SECRETS_ENV_READ

Why this grade

  • INSTALL_UNPINNED Low

    Dependencies use a range or git URL with no lockfile.

    requirements.txt, line 1 mcp>=1.2.0

  • NETWORK_NO_FIXED_HOST Low

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

    fetch.sh, line 28 if ! command -v curl &>/dev/null; then

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    .gitignore, line 9 .env

  • PERMISSION_SHELL_DECLARED Note

    Runs shell commands, and the manifest or description says so.

    demo/md2pdf.py, line 120 subprocess.run(

  • SECRETS_ENV_READ Note

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

    mcp_server/clients/shulex.py, line 60 key = os.environ.get("VOC_API_KEY", "").strip()

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.
