## Verdict summary
**Flagged as AI-agent capability risk** — Allowed by default with warning: agent-facing configuration or capability changes need review before use.

- **Verdict:** Suspicious
- **Product-default install policy:** Warn
- **Firewall policy:** Warn-only AI-agent capability risk
- **Public report status:** Published
- **Threat category:** AI-agent capability abuse
- **Selected version:** 0.1.957
- **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: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy.

Review flagged AI-agent configuration or capability changes. This remains warn-only unless evidence shows foreign-agent hijack through preinstall/install/postinstall, hidden persistence, exfiltration, remote code execution, or other concrete malicious behavior.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Suspicious
- **Recorded analysis confidence:** 88.0%
- **Started:** 2026-10-01T06:19:36.165Z
- **Finished:** 2026-10-01T06:21:38.936Z
- **Download time:** 770 ms
- **Static scan time:** 10617 ms
- **AI review time:** 111383 ms
- **Total time:** 122771 ms

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:** Interactive setup can persist MCP servers in shared agent configuration. This warrants a capability warning under the supplied policy; no confirmed malicious attack was established.

- **Trigger:** The user selects an add-server action in interactive MCP setup.

- **Impact:** Shared configuration changes can affect subsequent agent tool availability. The inspected flow is user-invoked, with no install-time hijack or demonstrated automatic extension update.

- **Evidence paths:** dist/src/chunk-UHBYG6JY.js, dist/src/index.js, dist/src/mcp-setup-panel-RG6Z4BOM.js

- **Review source:** ai\_review

- **Reviewed:** 2026-10-01T06:21:38.936Z

### AI review details

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

- **Mechanism:** Setup chooses a project or global configuration destination and writes the selected server entry into its MCP server object.

- **Rationale:** Static inspection did not establish malicious behavior. User-invoked writes to shared MCP agent configuration meet the supplied warning policy for explicit agent configuration capabilities.

- **Files touched:** .mcp.json, .config/mcp/mcp.json

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 88.0%

- **Recommended action:** downgrade\_to\_warn

- **Intent class:** Dangerous Capability

- **False-positive risk:** Medium

- **Evidence for warning:** Interactive MCP setup can add server entries to shared project or global agent configuration., The setup panel invokes configuration changes when the user selects an add-server action., The active engine bundle connects that action to the shared configuration writer., package.json has no preinstall, install, or postinstall hook.

- **Evidence against:** Configuration changes are exposed through interactive setup with write previews., Inspected credential code manages workspace authentication; no covert credential export was established.

## Affected versions and remediation

This report applies to replicas-engine@0.1.957.

- Review the evidence and your use of replicas-engine@0.1.957 before allowing it. Restrict the permissions described in this report.
- Choose an independently verified alternative or release. This report does not establish that other versions are safe.
