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

Rescanned at commit 5e8a6ec6f83a, unchanged since the check below.

SECRETS_PATH_DOTENV SECRETS_ENV_READ

Why this grade

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    src/japan_data_mcp/cli.py, line 100 # .env ファイル操作

  • SECRETS_ENV_READ Note

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

    src/japan_data_mcp/realestate/client.py, line 38 api_key = os.environ.get("REALESTATE_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.
