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

PERMISSION_SHELL_UNDECLARED SECRETS_PATH_CREDENTIAL

Why this grade

  • PERMISSION_SHELL_UNDECLARED Medium

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

    src/wpguard_mcp/transports/ssh_wpcli.py, line 65 proc = subprocess.run(ssh_cmd, capture_output=True, text=True, timeout=timeout)

  • SECRETS_PATH_CREDENTIAL Medium

    Mentions a credential store path (~/.ssh, id_rsa, .npmrc, .aws/credentials, credentials.json, .netrc).

    src/wpguard_mcp/transports/ssh_wpcli.py, line 5 normal SSH config (~/.ssh/config, agent forwarding, ProxyJump, known_hosts)

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.

    proc = subprocess.run(ssh_cmd, capture_output=True, text=True, timeout=timeout)

  • Install and update

    Pass

    docker-compose.yml, line 12

    env_file: .env

    docs/getting-started.md, line 34

    The generated token exists in that shell's environment. Store it in your secret manager or service configuration for subsequent starts. Configure the same value in the MCP client's

    cp .env.example .env
