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

Rescanned at commit 0e674eabf6c5, unchanged since the check below.

PERMISSION_DELETE_FILES NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV INSTALL_DOCUMENTED_INSTALLER OBFUSCATION_FILE_OVER_READ_CAP

Why this grade

  • PERMISSION_DELETE_FILES Low

    Contains a call that can delete files.

    src/zettelkasten_mcp/storage/note_repository.py, line 501 os.remove(file_path)

  • NETWORK_NO_FIXED_HOST Low

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

    docs/project-knowledge/dev/llms-full.txt, line 4704 const response = await fetch(url, { headers });

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    .gitignore, line 20 .env

  • INSTALL_DOCUMENTED_INSTALLER Note

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

    docs/project-knowledge/dev/llms-full.txt, line 4307 curl -LsSf https://astral.sh/uv/install.sh | sh

  • OBFUSCATION_FILE_OVER_READ_CAP Note

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

    docs/project-knowledge/dev/llms-full.txt, line 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.
