## 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:** 4.5.173
- **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 lifecycle hooks, and the inspected runtime telemetry is limited to CLI metadata sent to the MMI Hub endpoint. The targeted marketplace code reads marketplace settings; the inspected source does not establish a concrete attack.

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 was identified in the inspected source. CLI use triggers limited telemetry to the MMI Hub endpoint, and the targeted marketplace code reads registered Claude marketplace settings.

- **Trigger:** Running a CLI command triggers telemetry; package installation does not trigger a manifest lifecycle hook.

- **Impact:** No concrete attack impact was established from the inspected behavior.

- **Review source:** ai\_review

- **Reviewed:** 2026-10-17T09:29:22.735Z

### AI review details

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

- **Mechanism:** Telemetry sends the command name, version, CI status, and operating system. The inspected marketplace code reads the Claude marketplace registry and settings.

- **Rationale:** The manifest has no install lifecycle hooks, and the inspected runtime telemetry is limited to CLI metadata sent to the MMI Hub endpoint. The targeted marketplace code reads marketplace settings; the inspected source does not establish a concrete attack.

- **Files touched:** package.json, cli/dist/main.cjs

- **Network endpoints:** https://tqxxwzftic.execute-api.eu-central-1.amazonaws.com

### Review decision

- **Verdict:** Clean

- **Confidence:** 91.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** package.json declares no install lifecycle hooks., The targeted bundle location identifies Claude’s marketplace registry path and reads marketplace settings., On CLI command use, telemetry sends the command name, version, CI status, and operating system; the recipient is the configured MMI Hub endpoint., The telemetry call is attached to CLI command handling, not package installation., The bundle identifies the MMI Hub endpoint and permits an environment override.

- **Evidence against:** The inspected source shows no confirmed credential theft, unrelated data transfer, or unconsented agent configuration change.
