PERMISSION_SHELL_UNDECLARED

Why this grade

  • PERMISSION_SHELL_UNDECLARED Medium

    Runs shell commands that the manifest or description does not mention.

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

    Concern

    requests shell access. No manifest field names shell or command execution.

    PERMISSION_SHELL_UNDECLARED

  • Install and update

    Note

    The docs document an installer that pipes a download into a shell.

    INSTALL_DOCUMENTED_INSTALLER

    CONTRIBUTING.md, line 133

    curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

  • Network

    Concern

    can reach registry.modelcontextprotocol.io. The description does not name that host.

    NETWORK_UNNAMED_HOST

    scripts/release/publish-draft.sh, line 66

    listed() { curl -s --max-time 20 "https://registry.modelcontextprotocol.io/v0/servers?search=altium-designer-mcp" | grep -q "\"version\":\"$VERSION\""; }

  • Secrets

    Concern

    reads a credential or environment file.

    scripts/Generate-Samples.ps1, line 17
