Compatibility: Not stated.
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.
Rescanned at commit 79cc3b20377c, unchanged since the check below.
NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV PERMISSION_SHELL_DECLARED SECRETS_ENV_READ
Why this grade
- NETWORK_NO_FIXED_HOST Low
Makes a network call whose host is not written as a fixed address.
xaps_mcp_server.py, line 314
health = httpx.get(f"{base}/oracle/health", timeout=5.0) - SECRETS_PATH_DOTENV Low
Mentions a .env file.
test_crypto.py, line 7
# Load monorepo .env if present (parent of xaps-sdk/) - PERMISSION_SHELL_DECLARED Note
Runs shell commands, and the manifest or description says so.
docs/mcp-host-integration.md, line 109
proc = subprocess.Popen(['python','xaps_mcp_server.py'], stdin=subprocess.PIPE, stdout=subprocess.PIPE, text=True) - SECRETS_ENV_READ Note
Reads an environment variable whose name contains KEY, SECRET, TOKEN, PASSWORD or CREDENTIAL.
test_crypto.py, line 20
secret = os.getenv("XAPS_RECEIPT_SECRET") or os.getenv("BANK_WEBHOOK_SECRET")
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.
