Graded by PlugVetRubric v2

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

NETWORK_UNNAMED_HOST SECRETS_PATH_UNCONFIRMED SECRETS_ENV_READ

Why this grade

  • NETWORK_UNNAMED_HOST Low

    Calls a fixed host that the description does not name.

    scripts/check-version-bump.sh, line 21 pypi_version=$(curl -sf "https://pypi.org/pypi/${PACKAGE_NAME}/json" \

  • SECRETS_PATH_UNCONFIRMED Low

    The Secrets check reports a credential or environment file, but no quoted line shows a recognisable path.

    src/steam_mcp/auth.py, line 40 api_key = os.environ.get("STEAM_API_KEY")

  • SECRETS_ENV_READ Note

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

    src/steam_mcp/auth.py, line 40 api_key = os.environ.get("STEAM_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.
