## 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:** 0.1.960
- **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

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 MCP setup can persist server definitions in project or shared agent configuration. This is an explicit agent configuration capability; no confirmed attack was established.

- **Trigger:** A user selects a configuration-changing action in the runtime MCP setup panel.

- **Impact:** Changes can affect tools available to agents consuming the configuration. The inspected path requires an interactive action and does not establish covert mutation or automatic extension updates.

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

- **Review source:** ai\_review

- **Reviewed:** 2026-10-01T17:57:23.403Z

### AI review details

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

- **Mechanism:** Setup callbacks select the configuration destination, update server entries, persist the file, and reload configuration.

- **Rationale:** The inspected source does not establish malware. The supplied policy requires a warning for explicit user-command agent configuration mutation, which the MCP setup path implements.

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

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 90.0%

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

- **Intent class:** Dangerous Capability

- **False-positive risk:** Medium

- **Evidence for warning:** Interactive MCP setup writes server entries into project or shared agent configuration., Configuration destinations include .mcp.json and the home directory's .config/mcp/mcp.json., A selected setup-panel action activates the write; the panel displays a destination and configuration diff., The explicit setup command reloads configuration after changes., package.json defines no preinstall, install, or postinstall hook.

- **Evidence against:** No concrete malicious behavior was established in the inspected source., Agent credential changes occur through runtime credential managers, rather than npm installation., The GitHub CLI wrapper restricts automatic credential retrieval to github.com.

## Affected versions and remediation

This report applies to replicas-engine@0.1.960.

- Review the evidence and your use of replicas-engine@0.1.960 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.
