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

Rescanned at commit 85a0681d894c, unchanged since the check below.

NETWORK_NO_FIXED_HOST NETWORK_UNNAMED_HOST SECRETS_PATH_DOTENV INSTALL_DOCUMENTED_INSTALLER OBFUSCATION_FILE_OVER_READ_CAP

Why this grade

  • NETWORK_NO_FIXED_HOST Low

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

    docs/llms-full.txt, line 3129 fetch("/mcp", {

  • NETWORK_UNNAMED_HOST Low

    Calls a fixed host that the description does not name.

    docs/llms-full.txt, line 3129 fetch("/mcp", {

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    src/index.ts, line 100 '.env',

  • INSTALL_DOCUMENTED_INSTALLER Note

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

    docs/llms-full.txt, line 6048 curl -LsSf https://astral.sh/uv/install.sh | sh

  • OBFUSCATION_FILE_OVER_READ_CAP Note

    A file was over the read cap and was not fully read.

    package-lock.json, line 1 {

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.

What was checked

Plain notes from the hygiene checks.

  • Permissions

    Pass

    No shell or command execution found, and no extra permission was declared.

  • Install and update

    Note

  • Network

    Concern

    can reach a host that is not written as a fixed address. can reach api.weather.com. The description does not name that host.
