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

Rescanned at commit 54e4dcdcf9ee, unchanged since the check below.

NETWORK_NO_FIXED_HOST SECRETS_PATH_UNCONFIRMED 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/lc2mcp_server/templates/dashboard.html, line 623 fetch('/api/mcp/tools'),

  • SECRETS_PATH_UNCONFIRMED Low

    The Secrets check reports a credential or environment file, but no quoted line shows a recognisable path.

    src/lc2mcp_server/config.py, line 145 return os.getenv("OPENAI_API_KEY", "")

  • SECRETS_ENV_READ Note

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

    src/lc2mcp_server/config.py, line 145 return os.getenv("OPENAI_API_KEY", "")

  • 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.
