NETWORK_NO_FIXED_HOST NETWORK_UNNAMED_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.

    scripts/sync_docs.py, line 256 # serving 200 to curl and to browsers. Without this the fetch fails,

  • NETWORK_UNNAMED_HOST Low

    Calls a fixed host that the description does not name.

    scripts/sync_docs.py, line 256 # serving 200 to curl and to browsers. Without this the fetch fails,

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    src/spekoai_mcp/scaffolds.py, line 364 path=".env.example",

  • SECRETS_ENV_READ Note

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

    src/spekoai_mcp/auth.py, line 187 delegation_secret = (os.environ.get("SPEKOAI_MCP_DELEGATION_SECRET") or "").strip()

  • 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.

What was checked

Plain notes from the hygiene checks.

  • Permissions

    Pass

    No shell or command execution found, and no extra permission was declared.

  • Install and update

    Pass

    No install-time script found, and dependencies are pinned or absent.

  • Network

    Concern

    can reach a host that is not written as a fixed address. can reach api.speko.dev. The description does not name that host.
