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

Rescanned at commit 0db1e7d88165, unchanged since the check below.

SECRETS_PATH_UNCONFIRMED PERMISSION_SHELL_DECLARED INSTALL_DOCUMENTED_INSTALLER

Why this grade

  • SECRETS_PATH_UNCONFIRMED Low

    The Secrets check reports a credential or environment file, but no quoted line shows a recognisable path.

    .gitignore, line 55 # Environments

  • PERMISSION_SHELL_DECLARED Note

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

    src/nvim_mcp/discovery.py, line 129 result = subprocess.run(

  • INSTALL_DOCUMENTED_INSTALLER Note

    Documentation shows an installer that pipes a download into a shell.

    README.md, line 74 curl -LsSf https://astral.sh/uv/install.sh | sh

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.
