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

Rescanned at commit 977b4d126fed, unchanged since the check below.

INSTALL_UNPINNED NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV PERMISSION_SHELL_DECLARED SECRETS_ENV_READ OBFUSCATION_FILE_OVER_READ_CAP

Why this grade

  • INSTALL_UNPINNED Low

    Dependencies use a range or git URL with no lockfile.

    requirements.txt, line 8 mcp>=1.9.0

  • NETWORK_NO_FIXED_HOST Low

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

    src/powerbi_rest_connector.py, line 69 response = requests.get(url, headers=self._get_headers(), timeout=30)

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    README.md, line 248 copy .env.example .env

  • PERMISSION_SHELL_DECLARED Note

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

    run_tests.py, line 23 result = subprocess.run([sys.executable, str(t)], capture_output=True, text=True)

  • SECRETS_ENV_READ Note

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

    src/security/audit_logger.py, line 113 key = os.getenv("POWERBI_MCP_AUDIT_KEY")

  • OBFUSCATION_FILE_OVER_READ_CAP Note

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

    src/server.py, 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.

What was checked

Plain notes from the hygiene checks.

  • Permissions

    Note

    requests shell access. The manifest names this permission.

    PERMISSION_SHELL_DECLARED

    run_tests.py, line 23

    result = subprocess.run([sys.executable, str(t)], capture_output=True, text=True)

  • Install and update

    Concern

    dependencies are not pinned.

    INSTALL_UNPINNED

    requirements.txt, line 8

    mcp>=1.9.0

  • Network

    Concern

    can reach a host that is not written as a fixed address.

    NETWORK_NO_FIXED_HOST
