Grade B

Minor issues only, no Medium or High. Worth a quick look at the findings below before installing.

Graded by PlugVetRubric v2

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

Rescanned at commit c84bac23eb84, unchanged since the check below.

NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV PERMISSION_SHELL_DECLARED SECRETS_ENV_READ

Why this grade

  • NETWORK_NO_FIXED_HOST Low

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

    decision_engine/06_Router_MCP/lnbits_client.py, line 87 with urllib.request.urlopen(req, timeout=LNBITS_TIMEOUT_SECONDS) as response:

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    decision_engine/06_Router_MCP/l402_gateway_real.py, line 18 # Parse .env configurations manually to avoid external dependencies

  • PERMISSION_SHELL_DECLARED Note

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

    decision_engine/scripts/client_one.py, line 155 proc = subprocess.Popen(

  • SECRETS_ENV_READ Note

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

    decision_engine/06_Router_MCP/l402_gateway_real.py, line 37 ORACLE_SECRET_KEY = os.environ.get("ORACLE_SECRET_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.

  • Install and update

    Pass
