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

Rescanned at commit 8c1a390f10ab, unchanged since the check below.

NETWORK_NO_FIXED_HOST 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.

    src/github_chat_mcp/server.py, line 31 response = requests.post(

  • INSTALL_DOCUMENTED_INSTALLER Note

    Documentation shows an installer that pipes a download into a shell.

    README.md, line 34 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.

    src/github_chat_mcp/server.py, line 11 API_KEY = os.environ.get("GITHUB_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.
