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

Rescanned at commit 5db8bb20a391, 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.

    src/index.ts, line 122 const response = await fetch(url, {

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    CLAUDE.md, line 86 source .env && claude mcp add nanobanana-mcp "node" "dist/index.js" \

  • SECRETS_ENV_READ Note

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

    test-api.js, line 7 const ai = new GoogleGenAI({ apiKey: process.env.GOOGLE_AI_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.
