## Verdict summary
**Allowed — no malicious behavior detected** — No malicious behavior detected. 12 low-signal pattern(s) reviewed.

- **Verdict:** Clean
- **Product-default install policy:** Allow
- **Firewall policy:** No policy match
- **Public report status:** Published
- **Threat category:** None published
- **Selected version:** 0.10.0
- **Selected version is latest:** No
- **Analysis source:** AI Security Review (lpm-firewall-ai)

This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions.

AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy.

The install-time download is a package-aligned binary setup from its declared GitHub repository. Source inspection shows archive checksum and binary-version checks, with no concrete attack behavior established.

The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs.

## Security analysis

### Published attack-surface review

- **Summary:** No attack surface was identified. The postinstall downloads the package's native executable from its GitHub release and checks its archive checksum and reported version.

- **Trigger:** Installing the package runs its postinstall, except when the installer skips in CI or npm scripts are disabled.

- **Impact:** The inspected code supports the package's binary installation; no malicious behavior was established.

- **Review source:** ai\_review

- **Reviewed:** 2026-10-14T12:14:37.252Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** The installer fetches release assets over HTTPS, verifies the archive against the release checksum manifest, and checks the executable version.

- **Rationale:** The install-time download is a package-aligned binary setup from its declared GitHub repository. Source inspection shows archive checksum and binary-version checks, with no concrete attack behavior established.

- **Files touched:** package.json, scripts/install.js, scripts/runtime.js

- **Network endpoints:** https://github.com

### Review decision

- **Verdict:** Clean

- **Confidence:** 94.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** package.json declares a postinstall command that runs scripts/install.js., The installer calls the binary setup unless CI or disabled npm scripts cause it to skip., The installer downloads release assets from the package's GitHub repository over HTTPS., The runtime checks the downloaded archive against its SHA-256 manifest and verifies the binary's version.

- **Public source:** [View source](<https://unpkg.com/@spuentesp/lain-mcp@0.10.0/package.json>)

Install-time source downloads a native archive from a fixed external host without transport verification, extracts it, and installs an executable payload.

Public source snippet (untrusted):

```json
scripts.postinstall = node scripts/install.js
Install-time code downloads an unverified remote native executable, stages it locally, activates an executable path, and exposes it to process execution.
