Why this grade

  • NETWORK_NAMED_HOST Note

    Calls a fixed host that the description names.

    etch_mcp_local/__init__.py, line 15 curl -X POST https://etch.systems/v1/your-project

  • SECRETS_ENV_READ Note

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

    etch_mcp_local/server.py, line 45 bearer = (os.environ.get("ETCH_BEARER_TOKEN") or "").strip()

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.
