create-zuplo-api@7.8.5
Create Zuplo API with one command
AI Security Review
scanned 1mo ago · by lpm-firewall-aiThis is a user-run Zuplo project scaffolder with no install lifecycle hook. It mutates AI-agent control files and downloads vendor skill markdown only after an explicit agent choice, which is a consented first-party setup capability rather than a hidden install attack.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
User execution of the create-zuplo-api bin with an interactive agent selection or the --agents flag.
Impact
The new project gains vendor agent instructions and an HTTP MCP client for Zuplo docs, plus Claude plugin and marketplace settings, only inside that project and only after the user opts in.
Mechanism
The CLI writes .mcp.json, agent instruction files, and for Claude a .claude/settings.json that enables project MCP servers and the zuplo/tools marketplace, then downloads and extracts SKILL.md files from the zuplo/tools tarball.

Decision evidence
public snapshotAI called this Suspicious at 84.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The published bin is dist/index.js and package.json has no preinstall, install, or postinstall hook.
- Agent files are written only after an interactive multiselect or an explicit --agents value; CI and --yes leave the agent list empty.
- Choosing Claude writes .claude/settings.json with enableAllProjectMcpServers and a zuplo/tools marketplace, plus .mcp.json for the Zuplo docs MCP.
- Selected non-Claude agents also receive instruction files, and skills are fetched from the zuplo/tools GitHub tarball with a 10MB cap and a SKILL.md-only extract filter.
Evidence against
- No lifecycle script runs this code during npm install.
- The agent prompt defaults to skipping setup in CI and with --yes, and offers an explicit none choice.
- The remote fetch is limited to markdown skill files from the vendor zuplo/tools repository, not an arbitrary executable payload.
