Rescanned at commit f1a614013bd1, unchanged since the check below.

NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV 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.

    scripts/update_smithery_metadata.sh, line 25 HTTP_CODE=$(curl -sS -o /tmp/smithery_resp.json -w "%{http_code}" -X PATCH "$API" \

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    src/mtg_mcp_server/config.py, line 3 All settings use the ``MTG_MCP_`` prefix and can be overridden via a ``.env``

  • OBFUSCATION_FILE_OVER_READ_CAP Note

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

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.
