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

Rescanned at commit c999b50e1a72, unchanged since the check below.

SECRETS_PATH_DOTENV PERMISSION_SHELL_DECLARED INSTALL_DOCUMENTED_INSTALLER SECRETS_ENV_READ OBFUSCATION_FILE_OVER_READ_CAP

Why this grade

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    benchmark/cli/run.py, line 29 """Load .env file from MCP_DOTENV_PATH or default locations.

  • PERMISSION_SHELL_DECLARED Note

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

    benchmark/cli/grid.py, line 208 completed = subprocess.run( # nosec B603

  • INSTALL_DOCUMENTED_INSTALLER Note

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

    CONTRIBUTING.md, line 11 curl -LsSf https://astral.sh/uv/install.sh | sh

  • SECRETS_ENV_READ Note

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

    benchmark/cli/run.py, line 63 relace_api_key = os.getenv("RELACE_API_KEY", "").strip()

  • 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.
