Grade B

Minor issues only, no Medium or High. Worth a quick look at the findings below before installing.

Graded by PlugVetRubric v2

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

SECRETS_PATH_DOTENV SECRETS_ENV_READ

Why this grade

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    src/ch06/mcp_client.py, line 21 # 加载 .env 文件，确保 API Key 受到保护

  • SECRETS_ENV_READ Note

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

    src/weather.py, line 26 API_KEY = os.getenv("OPENWEATHER_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.

What was checked

Plain notes from the hygiene checks.

    Concern

    reads a credential or environment file.

    API_KEY = os.getenv("OPENWEATHER_API_KEY")

    # 加载 .env 文件，确保 API Key 受到保护

    src/ch06/mcp_client.py, line 31

    raise ValueError("❌ 未找到 OpenAI API Key，请在 .env 文件中设置 OPENAI_API_KEY")

    src/ch06/weather.py, line 26

    API_KEY = os.getenv("OPENWEATHER_API_KEY")

    src/ch07/weather.py, line 26

    API_KEY = os.getenv("OPENWEATHER_API_KEY")

    2. 在项目根目录下新建`.env`文件，并添加以下内容

    README.md, line 42

    4. 在项目根目录下新建`.env`文件，并添加以下内容

    docs/ch06/ch06.md, line 75

    # 加载 .env 文件中的环境变量，方便管理 API Key 等敏感信息

    docs/ch06/ch06.md, line 196

    与服务器一样，客户端也需要配置。这里使用[硅基流动](https://cloud.siliconflow.cn/)的大模型服务，并通过环境变量来管理 API 密钥等敏感信息。确保项目根目录下的 `.env` 文件包含以下内容：

    docs/ch06/ch06.md, line 208

    首先，定义 `MCPClient` 类的构造函数 `__init__`。它负责加载 `.env` 文件中的配置，并初始化一个 OpenAI 客户端实例。
