Graded by PlugVetRubric v2

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

SECRETS_PATH_DOTENV OBFUSCATION_ENCODED_BLOB

Why this grade

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    src/mcp_ksef_pl/config.py, line 29 model_config = SettingsConfigDict(env_prefix="KSEF_", env_file=".env", extra="ignore")

  • OBFUSCATION_ENCODED_BLOB Low

    Contains a long base64 shaped string in a file that should be readable.

    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.
