Grades are a hygiene check, not a security guarantee.

MCP, MCP server

Apprentice

Apprentice 0.3 now uses OpenCode for terminal chat, the VS Code panel, and MCP assign; Aider is legacy-only.

Compatibility: Not stated.

Grade B

Minor issues only, no Medium or High. Worth a quick look at the findings below before installing.

Graded by PlugVetRubric v2

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

PERMISSION_DELETE_FILES NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV SECRETS_ENV_READ

Why this grade

  • PERMISSION_DELETE_FILES Low

    Contains a call that can delete files.

    src/agent.py, line 30 proc = subprocess.run(cmd, cwd=cwd, timeout=timeout, capture_output=True,

  • NETWORK_NO_FIXED_HOST Low

    Makes a network call whose host is not written as a fixed address.

    src/chat_providers.py, line 117 with urllib.request.urlopen(req, timeout=timeout_s) as resp:

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    .gitignore, line 11 .env

  • SECRETS_ENV_READ Note

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

    src/chat_providers.py, line 439 if creds and not os.environ.get("GOOGLE_APPLICATION_CREDENTIALS"):

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.
