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

Rescanned at commit 887097adcc0c, unchanged since the check below.

SECRETS_PATH_UNCONFIRMED SECRETS_ENV_READ

Why this grade

  • SECRETS_PATH_UNCONFIRMED Low

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

    mcp_server_bing/server.py, line 108 api_key = os.environ.get("BING_API_KEY", "")

  • SECRETS_ENV_READ Note

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

    mcp_server_bing/server.py, line 108 api_key = os.environ.get("BING_API_KEY", "")

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.
