## Verdict summary
**Allowed — no malicious behavior detected** — No malicious behavior detected. 14 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:** 0.1.36
- **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 manifest has no install-time hook; its prepublishOnly script builds and obfuscates the published code. Despite reduced transparency from obfuscation, inspected runtime behavior is consistent with the launcher and portal client, with no concrete malicious behavior identified.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Clean
- **Recorded analysis confidence:** 89.0%

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:** The inspected code supports a launcher and portal-backed MCP server. No attack surface was identified.

- **Trigger:** A user runs the CLI launcher or MCP server.

- **Impact:** No attack impact was established. Feedback reporting contains tool and error metadata sent through the configured portal client.

- **Review source:** ai\_review

- **Reviewed:** 2026-10-18T05:21:33.931Z

### AI review details

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

- **Mechanism:** The launcher prepares an MCP configuration and starts a child process; the server uses caller-supplied portal settings and standard I/O.

- **Rationale:** The manifest has no install-time hook; its prepublishOnly script builds and obfuscates the published code. Despite reduced transparency from obfuscation, inspected runtime behavior is consistent with the launcher and portal client, with no concrete malicious behavior identified.

### Review decision

- **Verdict:** Clean

- **Confidence:** 89.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** package.json runs a build and obfuscation step only in prepublishOnly; it declares no install hook., The launcher writes an MCP configuration and starts a child process with its environment., The MCP server requires a supplied portal URL and token, then starts on standard I/O., Feedback reports qualifying tool errors with tool and error metadata through the portal client., The published index bundle uses string-table obfuscation, which reduces transparency.

- **Evidence against:** The published JavaScript is heavily obfuscated, limiting direct review of some implementation details.
