Graded by PlugVetRubric v2

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

SECRETS_PATH_DOTENV SECRETS_ENV_READ

Why this grade

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    03-mcp-weather/mcp-client/client.py, line 14 load_dotenv() # load environment variables from .env

  • SECRETS_ENV_READ Note

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

    01-hello-world/client-deepseek.py, line 27 api_key=os.getenv("DEEPSEEK_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.
