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.
host-helper/install.mjs, line 75
To verify: curl http://127.0.0.1:8789/health - SECRETS_PATH_DOTENV Low
Mentions a .env file.
.env.example, line 2
# Copy to .env (git-ignored) only if you need to override something. - SECRETS_ENV_READ Note
Reads an environment variable whose name contains KEY, SECRET, TOKEN, PASSWORD or CREDENTIAL.
packages/mcp-server/src/config.ts, line 41
if (process.env.AB_BRIDGE_SECRET_FILE) cfg.bridge.secretFile = process.env.AB_BRIDGE_SECRET_FILE;
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.
