Grade B
Minor issues only, no Medium or High. Worth a quick look at the findings below before installing.
Not a guarantee. A hygiene check of the source at the commit shown, not a security audit.
PERMISSION_DELETE_FILES INSTALL_UNPINNED NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV INSTALL_DOCUMENTED_INSTALLER SECRETS_ENV_READ
Why this grade
- PERMISSION_DELETE_FILES Low
Contains a call that can delete files.
npm-wrapper/bin/arkheia-mcp.js, line 572
fs.rmSync(VENV_DIR, { recursive: true, force: true }); - INSTALL_UNPINNED Low
Dependencies use a range or git URL with no lockfile.
install.sh, line 6
# curl -fsSL https://arkheia.ai/install-mcp | bash - NETWORK_NO_FIXED_HOST Low
Makes a network call whose host is not written as a fixed address.
AGENTS.md, line 15
curl -X POST https://arkheia-proxy-production.up.railway.app/v1/provision \ - SECRETS_PATH_DOTENV Low
Mentions a .env file.
proxy/config.py, line 122
"env_file": None, # never load from .env file - INSTALL_DOCUMENTED_INSTALLER Note
Documentation shows an installer that pipes a download into a shell.
install.sh, line 6
# curl -fsSL https://arkheia.ai/install-mcp | bash - SECRETS_ENV_READ Note
Reads an environment variable whose name contains KEY, SECRET, TOKEN, PASSWORD or CREDENTIAL.
conftest.py, line 17
if not os.environ.get("JWT_SECRET") or len(os.environ.get("JWT_SECRET", "")) < 32:
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.

Install and update
Concern
dependencies are not pinned. The docs document an installer that pipes a download into a shell.
