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

Rescanned at commit 8bc4b51d7eb0.

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.

    src/qcdatabase_mcp/auth.py, line 160 resp = httpx.post(_REGISTER_URL, json=payload, timeout=30.0)

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    scripts/run-server.sh, line 6 # Configuration comes from the environment, or from a .env file in the repo

  • SECRETS_ENV_READ Note

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

    src/qcdatabase_mcp/hosted.py, line 303 return float(os.environ.get("QCDB_MCP_TOKEN_CACHE_TTL", "60"))

  • OBFUSCATION_FILE_OVER_READ_CAP Note

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

    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.
