Graded by PlugVetRubric v2

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

Rescanned at commit d666bac37435, unchanged since the check below.

SECRETS_PATH_DOTENV NETWORK_LOCALHOST SECRETS_ENV_READ OBFUSCATION_FILE_OVER_READ_CAP

Why this grade

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    .dockerignore, line 30 .env

  • NETWORK_LOCALHOST Note

    Calls localhost only.

    Dockerfile, line 99 CMD ["python", "-c", "import sys, urllib.request, urllib.error\ntry:\n urllib.request.urlopen('http://localhost:8000/mcp', timeout=4)\nexcept urllib.error.HTTPError:\n sys.ex

  • SECRETS_ENV_READ Note

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

    src/cve_mcp/config.py, line 66 NVD_API_KEY: str = os.getenv("NVD_API_KEY", "")

  • OBFUSCATION_FILE_OVER_READ_CAP Note

    A file was over the read cap and was not fully read.

    uv.lock, line 1 version = 1

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.
