create-zuplo-api@7.8.2
Create Zuplo API with one command
AI Security Review
scanned 1mo ago · by lpm-firewall-aiThis is a user-run Zuplo scaffolder with no install hook, but choosing agents writes first-party AI-agent instruction and MCP files and pulls unpinned skill text from GitHub. That is an explicit agent-control capability, so it warrants a warning rather than a publish block.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
A person runs the create-zuplo-api bin and selects agents in the prompt or passes --agents.
Impact
The new project receives vendor skill text and an MCP endpoint. This is operator-selected project setup, not a silent install-time takeover of a global agent configuration.
Mechanism
The CLI fetches the unpinned zuplo/tools main tarball, keeps SKILL.md files, and writes project files such as .mcp.json, .claude/settings.json, and agent instruction files that reference the Zuplo docs MCP server.

Decision evidence
public snapshotAI called this Suspicious at 78.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The published bin is a user-run CLI and package.json has no preinstall, install, or postinstall hook.
- When agents are chosen by prompt or --agents, the CLI writes .mcp.json, Claude settings, and agent instruction files into the new project.
- That path downloads the unpinned zuplo/tools main tarball and copies SKILL.md files into vendor agent skill directories.
- Generated MCP config sets enableAllProjectMcpServers and points zuplo_docs at the Zuplo docs MCP URL.
Evidence against
- Agent setup is skipped when the user picks none, passes --agents none, or runs non-interactively without a selection.
- The download is size-capped and filtered to SKILL.md files from the zuplo GitHub repository.
- No credential harvest, hidden eval, or install-time mutation of a global agent directory was found.
