Graded by PlugVetRubric v2

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

PERMISSION_DELETE_FILES NETWORK_NO_FIXED_HOST NETWORK_UNNAMED_HOST SECRETS_PATH_DOTENV INSTALL_DOCUMENTED_INSTALLER SECRETS_ENV_READ OBFUSCATION_FILE_OVER_READ_CAP

Why this grade

  • PERMISSION_DELETE_FILES Low

    Contains a call that can delete files.

    swag_mcp/services/backup_manager.py, line 267 await self.fs.unlink(candidate.path)

  • NETWORK_NO_FIXED_HOST Low

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

    install.sh, line 35 curl -sO https://raw.githubusercontent.com/jmagar/swag-mcp/main/docker-compose.yaml || {

  • NETWORK_UNNAMED_HOST Low

    Calls a fixed host that the description does not name.

    install.sh, line 35 curl -sO https://raw.githubusercontent.com/jmagar/swag-mcp/main/docker-compose.yaml || {

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    install.sh, line 40 # Handle existing .env file

  • INSTALL_DOCUMENTED_INSTALLER Note

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

    docs/stack/PRE-REQS.md, line 10 | uv | latest | Dependency management | `curl -LsSf https://astral.sh/uv/install.sh \| sh` |

  • SECRETS_ENV_READ Note

    Reads an environment variable whose name contains KEY, SECRET, TOKEN, PASSWORD or CREDENTIAL.

    swag_mcp/server.py, line 443 token = os.getenv("SWAG_MCP_TOKEN")

  • OBFUSCATION_FILE_OVER_READ_CAP Note

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

    uv.lock, line 1 version = 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

    Concern

    can delete files.

    PERMISSION_DELETE_FILES

    swag_mcp/services/backup_manager.py, line 267

    await self.fs.unlink(candidate.path)

    swag_mcp/services/config_operations.py, line 486

    await self.fs.unlink(str(config_file))

    swag_mcp/services/file_operations.py, line 131

    await self.fs.unlink(str(file_path))

  • Install and update

    Note

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