Grade C

One Medium finding. Read the findings before installing.

Graded by PlugVetRubric v2

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

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).

    script/lint, line 12 curl -sSfL https://golangci-lint.run/install.sh | sh -s -- -b "$BINDIR" "$GOLANGCI_LINT_VERSION"

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

    Note

    requests shell access. The manifest names this permission.

    PERMISSION_SHELL_DECLARED

    cmd := exec.Command(cmdParts[0], cmdParts[1:]...) //nolint:gosec //mcpcurl is a test command that needs to execute arbitrary shell commands

  • Install and update

    Serious

    install fetches a script from the network.

    INSTALL_REMOTE_SCRIPT

    script/lint, line 12

    curl -sSfL https://golangci-lint.run/install.sh | sh -s -- -b "$BINDIR" "$GOLANGCI_LINT_VERSION"

  • Network

    Concern

    can reach a host that is not written as a fixed address.

    NETWORK_NO_FIXED_HOST

  • Secrets

    Concern

    reads a credential or environment file.

    SECRETS_ENV_READ SECRETS_PATH_DOTENV

    e2e/e2e_test.go, line 48

    token = os.Getenv("GITHUB_MCP_SERVER_E2E_TOKEN")

    README.md, line 229

    Or create a `.env` file:

    2. **Protect your `.env` file**

    1. Store your token in `.env` file

  • Agent instructions

    Pass

    No instruction to ignore earlier instructions or to hide a step.

  • Obfuscation

    Concern

    contains an encoded blob in a file that should be readable.
