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.

NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV SECRETS_ENV_READ
Why this grade
- NETWORK_NO_FIXED_HOST Low
Makes a network call whose host is not written as a fixed address.
src/trust_gate_mcp/server_http.py, line 130
fetch("/x?via=" + encodeURIComponent(via) + "&kind=page", - SECRETS_PATH_DOTENV Low
Mentions a .env file.
src/trust_gate_mcp/server.py, line 312
# as does any hidden or parent-directory segment (.env, .ssh, .git, ..). A bare name with no - SECRETS_ENV_READ Note
Reads an environment variable whose name contains KEY, SECRET, TOKEN, PASSWORD or CREDENTIAL.
src/trust_gate_mcp/api_ops.py, line 82
key = os.environ.get("TRUST_GATE_API_KEY", "").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.
