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

Rescanned at commit 665f962e9596, unchanged since the check below.

INSTALL_UNPINNED NETWORK_NO_FIXED_HOST SECRETS_PATH_UNCONFIRMED

Why this grade

  • INSTALL_UNPINNED Low

    Dependencies use a range or git URL with no lockfile.

    requirements.txt, line 1 mcp

  • NETWORK_NO_FIXED_HOST Low

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

    src/prometheus_mcp_server/server.py, line 91 "description": "specific range of metric to fetch(number of minutes)",

  • SECRETS_PATH_UNCONFIRMED Low

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

    .gitignore, line 17 env/

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.
