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 286b9e7b732a, unchanged since the check below.
NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV INSTALL_DOCUMENTED_INSTALLER SECRETS_ENV_READ
Why this grade
- NETWORK_NO_FIXED_HOST Low
Makes a network call whose host is not written as a fixed address.
examples/fastmcp_client.py, line 38
response = requests.get(self.health_endpoint, timeout=10) - SECRETS_PATH_DOTENV Low
Mentions a .env file.
template_mcp_server/src/settings.py, line 20
logger.warning(f"Could not load .env file: {e}") - INSTALL_DOCUMENTED_INSTALLER Note
Documentation shows an installer that pipes a download into a shell.
docs/development.md, line 16
curl -LsSf https://astral.sh/uv/install.sh | sh - SECRETS_ENV_READ Note
Reads an environment variable whose name contains KEY, SECRET, TOKEN, PASSWORD or CREDENTIAL.
examples/langgraph_client.py, line 53
gemini_api_key = os.getenv("GEMINI_API_KEY")
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.
