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

Rescanned at commit b84c3131e64c, unchanged since the check below.

SECRETS_PATH_DOTENV PERMISSION_SHELL_DECLARED SECRETS_ENV_READ

Why this grade

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    docker-compose.yml, line 4 # Make sure JOPLIN_TOKEN is set in your environment or in a .env file

  • PERMISSION_SHELL_DECLARED Note

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

    bootstrap.py, line 48 result = subprocess.run([str(python), str(Path(__file__).resolve()), *sys.argv[1:]])

  • SECRETS_ENV_READ Note

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

    src/joplin_mcp/fastmcp_server.py, line 280 token = os.getenv("JOPLIN_TOKEN")

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.
