## 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:** 0.11.3
- **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:** 90.0%

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:** Authenticated configuration actions can redirect external AI clients and change Claude Desktop's deployment mode. This is a user-triggered capability; no confirmed malicious attack was established.

- **Trigger:** An authenticated user submits an AI-client configuration request.

- **Impact:** Subsequent AI-client requests use the configured gateway and models, warranting a capability warning under the supplied policy.

- **Evidence paths:** src/server/cli-tools/claude.ts, src/server/cli-tools/cowork.ts, src/server/cli-tools/registry.ts, src/server/routes/cli-tools.routes.ts, src/index.ts

- **Review source:** ai\_review

- **Reviewed:** 2026-10-02T23:58:10.437Z

### AI review details

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

- **Mechanism:** The selected integration writes gateway, model, authentication, and deployment settings into external client configuration files.

- **Rationale:** The source exposes explicit, authenticated AI-agent configuration mutation, which the supplied policy classifies as a warning. The inspected lifecycle and runtime behavior do not establish a block-eligible malicious chain.

- **Files touched:** .claude/settings.json

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 90.0%

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

- **Intent class:** Dangerous Capability

- **False-positive risk:** Medium

- **Evidence for warning:** Claude Code integration changes the gateway and authentication settings in .claude/settings.json., Claude Desktop integration writes inference configuration and switches deploymentMode to third-party mode., Configuration changes require an explicit request through session-authenticated API routes., The shared configuration writer persists these changes to disk., The install hook registers only package-owned startup entries, with an environment-variable opt-out.

- **Evidence against:** No inspected source established covert exfiltration, remote payload execution, or install-time mutation of foreign AI-agent settings., Provider credentials originate from caller-supplied account keys; the version service queries the package's npm registry endpoint.

## Affected versions and remediation

This report applies to kcgrouter@0.11.3.

- Review the evidence and your use of kcgrouter@0.11.3 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.
