NETWORK_NO_FIXED_HOST SECRETS_ENV_READ
Why this grade

Makes a network call whose host is not written as a fixed address.
paper_mcp/server.py, line 482
paper = await src.fetch(paper_id) - SECRETS_ENV_READ Note
Reads an environment variable whose name contains KEY, SECRET, TOKEN, PASSWORD or CREDENTIAL.
paper_mcp/medical.py, line 35
NCBI_API_KEY = os.getenv("NCBI_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.
