Rescanned at commit 59874d0da838, unchanged since the check below.

INSTALL_REMOTE_SCRIPT

Why this grade

  • INSTALL_REMOTE_SCRIPT Medium

    Fetches a script from the network and runs it (a pipe to a shell, or an install hook with a URL).

    commands/seo-setup.md, line 39 > Run this in your terminal: `curl -LsSf https://astral.sh/uv/install.sh | sh` then restart your shell. Tell me when done.

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.

If you think this grade is wrong, email [email protected] with the entry link and your evidence. We aim to acknowledge within two working days and decide within seven. If we confirm an error, we aim to correct it within 24 hours of confirming it. These are aims, not guarantees.

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

    Note

    requests shell access. The manifest names this permission.

    PERMISSION_SHELL_DECLARED

    mcp-servers/geo-check/server.py, line 107

    out = subprocess.run(

    scripts/check.py, line 94

    res = subprocess.run(cmd, capture_output=True, text=True, timeout=10)

  • Install and update

    Serious

    install fetches a script from the network. The docs document an installer that pipes a download into a shell.

    INSTALL_REMOTE_SCRIPT INSTALL_DOCUMENTED_INSTALLER

    MCP_SETUP.md, line 7

    - `uv` ≥ 0.5 - `curl -LsSf https://astral.sh/uv/install.sh | sh`

    commands/seo-setup.md, line 39

    > Run this in your terminal: `curl -LsSf https://astral.sh/uv/install.sh | sh` then restart your shell. Tell me when done.

    scripts/check.sh, line 63

    fail "uvx not on PATH. Install: curl -LsSf https://astral.sh/uv/install.sh | sh"

  • Network

    Concern
