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

Rescanned at commit a534b5a995d5, unchanged since the check below.

NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV INSTALL_DOCUMENTED_INSTALLER

Why this grade

  • NETWORK_NO_FIXED_HOST Low

    Makes a network call whose host is not written as a fixed address.

    .cursor/rules/mcp-llms-full.mdc, line 4281 const response = await fetch(url, { headers });

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    .cursor/rules/mcp-llms-full.mdc, line 2602 * Always use absolute paths in your configuration and `.env` files to ensure reliable operation

  • INSTALL_DOCUMENTED_INSTALLER Note

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

    .cursor/rules/mcp-llms-full.mdc, line 3884 curl -LsSf https://astral.sh/uv/install.sh | sh

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.
