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

Rescanned at commit 707f4fbb464d, unchanged since the check below.

NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV SECRETS_ENV_READ

Why this grade

  • NETWORK_NO_FIXED_HOST Low

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

    slc_mcp_server.py, line 85 with urllib.request.urlopen(req, timeout=25) as r:

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    slc_mcp_server.py, line 39 """从脚本同目录的 .env 读取 SLC_API_KEY（仅当环境变量未设置时）。

  • SECRETS_ENV_READ Note

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

    slc_mcp_server.py, line 35 return (os.environ.get("SLC_API_KEY") or "").strip()

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.
