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

NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV SECRETS_ENV_READ OBFUSCATION_FILE_OVER_READ_CAP

Why this grade

  • NETWORK_NO_FIXED_HOST Low

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

    app/apis/holidays/kasi.py, line 71 resp = httpx.get(BASE_URL, params=params, timeout=10.0)

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    app/core/config.py, line 7 model_config = SettingsConfigDict(env_prefix="KDS_", env_file=".env", extra="ignore")

  • SECRETS_ENV_READ Note

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

    packages/korea-data-mcp/src/korea_data_mcp/server.py, line 22 API_KEY = os.environ.get("KDS_API_KEY", "")

  • OBFUSCATION_FILE_OVER_READ_CAP Note

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

    packages/korea-data-mcp/uv.lock, line 1 version = 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.
