## Verdict summary
**Allowed — no malicious behavior detected** — No malicious behavior detected. 16 low-signal pattern(s) reviewed.

- **Verdict:** Manual Review
- **Product-default install policy:** Allow
- **Firewall policy:** No policy match
- **Public report status:** Under Review
- **Threat category:** Unknown
- **Selected version:** 0.2.88
- **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: manual review; recommendation: manual review. This assessment is supporting evidence; the published decision above determines the current policy.

Inspected source shows a checkout-only postinstall path, a launcher for the bundled server, fixed GPU information commands, and an intentional remote-agent token transfer. Manual review is needed because several selected runtime dependency implementations were metadata-only in the prepared source snapshot.

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 concrete attack was established in the inspected package-owned code. Several imported runtime dependency implementations remain unverified in the prepared source snapshot.

- **Trigger:** When the server starts and loads its declared runtime dependencies.

- **Impact:** The behavior of those dependency implementations could not be assessed from the inspected source.

- **Evidence paths:** package.json, node-server/dist/index.js

- **Review source:** ai\_review

- **Reviewed:** 2026-10-25T13:23:49.553Z

### AI review details

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

- **Mechanism:** The server imports registry packages whose implementations were not available for this review.

- **Rationale:** Inspected source shows a checkout-only postinstall path, a launcher for the bundled server, fixed GPU information commands, and an intentional remote-agent token transfer. Manual review is needed because several selected runtime dependency implementations were metadata-only in the prepared source snapshot.

### Review decision

- **Verdict:** Manual Review

- **Confidence:** 70.0%

- **Recommended action:** manual\_review

- **Intent class:** Unknown

- **False-positive risk:** Medium

- **AI review observations:** The postinstall hook is declared in package.json; its helper exits under node\_modules and otherwise targets only the checkout’s autocomplete, server, and MCP subpackages., The launcher starts the packaged server with the supplied arguments. The GPU shell calls use fixed NVIDIA and AMD information queries., The remote-agent route forwards the request’s bearer token over the configured reverse channel to the user’s remote machine before launch., The manifest declares runtime dependencies that the server imports, including Fastify. Several selected dependency implementations were metadata-only in the prepared source snapshot, so their behavior remains unverified.
