Graded by PlugVetRubric v2

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

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/tools/transactions.ts, line 17 week: weekSchema.describe("Week to fetch (default: current week). Ignored when all_weeks=true."),

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    .gitignore, line 7 .env

  • SECRETS_ENV_READ Note

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

    src/http.ts, line 41 const authToken = options.authToken === undefined ? (process.env.SLEEPER_MCP_AUTH_TOKEN ?? null) : options.authToken;

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.
