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

Rescanned at commit 858f110a00b6, unchanged since the check below.

NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV SECRETS_ENV_READ

Why this grade

  • NETWORK_NO_FIXED_HOST Low

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

    examples/agent_pays_for_scan.py, line 41 urllib.request.urlopen(req, timeout=20)

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    .env.example, line 1 # xrpl-utilities-mcp - example environment. Copy to .env (gitignored) and fill.

  • SECRETS_ENV_READ Note

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

    bench/live_payment_via_mcp.py, line 131 bypass_key = os.environ.get("D_BYPASS_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.
