Is harper-fabric-embeddings safe?
- npm install-time lifecycle hook
- Node.js network egress
What to do: Nothing here argues against installing it. Grant the capabilities it lists only if you expect the tool to need them.
harper-fabric-embeddings is an npm package analyzed by SkillTotal's deterministic static scanner. The scan found no malicious indicators. It can: install time execution and network egress — capabilities are what the code can do, not a verdict on intent. Risk score 0/100 (low).

Behavioral traits
How this component maps to the CSA agentic threat model. Descriptive — it never affects the risk score.
Findings (2)
package.json runs scripts automatically when the package is installed.
"postinstall": "node setup.js"
Why it matters: Install scripts are a favorite supply-chain foothold — they execute on every machine that installs the package.
Fix: Inspect the hook command. Install-time scripts are a common supply chain execution vector; ensure they do nothing beyond a documented build step.
The component makes outbound network requests.
const response = await fetch(url, {Why it matters: Usually legitimate, but confirm the destinations are expected and no sensitive data leaves.
Fix: Confirm the destination hosts are expected and that no sensitive data is sent off-host.
How attackers abuse these capabilities

The free Claude Code plugin scans each npm, PyPI or MCP package with this report's open-source engine before the install command runs. It runs on your machine and needs no account.
