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

Rescanned at commit a5def2dccff6, unchanged since the check below.

NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV PERMISSION_SHELL_DECLARED

Why this grade

  • NETWORK_NO_FIXED_HOST Low

    Makes a network call whose host is not written as a fixed address.

    packages/mne-cpp-mcp/src/mne_cpp_mcp/setup.py, line 58 urllib.request.urlopen(request, timeout=30) as response,

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    src/mne_mcp/config.py, line 18 # Load .env from project root first and let repo-local settings override inherited shell values.

  • PERMISSION_SHELL_DECLARED Note

    Runs shell commands, and the manifest or description says so.

    scripts/install.py, line 42 result = subprocess.run(

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.
