Not a guarantee. A hygiene check of the source at the commit shown, not a security audit.

Rescanned at commit 5d97ef73480c, 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.

    catalyst_mcp.py, line 110 with urllib.request.urlopen(req, timeout=15) as r:

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    catalyst_mcp.py, line 90 for path in ("/opt/catalyst/.env", str(_HERE.parent / ".env")):

  • PERMISSION_SHELL_DECLARED Note

    Runs shell commands, and the manifest or description says so.

    smoke_test.py, line 51 r = subprocess.run([sys.executable, str(SERVER)], input=inp,

  • SECRETS_ENV_READ Note

    Reads an environment variable whose name contains KEY, SECRET, TOKEN, PASSWORD or CREDENTIAL.

    catalyst_mcp.py, line 475 tier = tier_for_key(os.environ.get("CATALYST_MCP_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.
