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

Rescanned at commit dd91577d6972, unchanged since the check below.

NETWORK_NO_FIXED_HOST NETWORK_UNNAMED_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.

    experiments/mcp-2026/scripts/capture-p2-evidence.mjs, line 56 execute: () => fetch(`${endpoint}/health`),

  • NETWORK_UNNAMED_HOST Low

    Calls a fixed host that the description does not name.

    experiments/mcp-2026/scripts/capture-p2-evidence.mjs, line 56 execute: () => fetch(`${endpoint}/health`),

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    .dockerignore, line 5 .env

  • SECRETS_ENV_READ Note

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

    benchmarks/ai-review.mjs, line 31 const apiKey = process.env.OPENAI_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.
