Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## 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:** 0.3.477 - **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. This is a real AI-agent configuration capability whose exact caller and consent flow are obscured by the bundled code. There is no inspected evidence of an install hook, credential theft, remote payload download, or automatic configuration mutation. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 84.0% - **Started:** 2026-09-29T23:33:23.825Z - **Finished:** 2026-09-29T23:34:32.992Z - **Download time:** 1780 ms - **Static scan time:** 1932 ms - **AI review time:** 65453 ms - **Total time:** 69167 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:** The package contains runtime functionality that can register MCP server commands in an AI-agent configuration. No automatic install-time attack was identified. - **Trigger:** A user-invoked MCP or agent configuration operation using the package command options. - **Impact:** A user who applies an untrusted configuration could grant that MCP server agent-level capabilities; the inspected manifest does not show this occurring automatically during installation. - **Evidence paths:** dist/mcp.cjs - **Review source:** ai\_review - **Reviewed:** 2026-09-29T23:34:32.992Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The bundle edits an MCP server configuration entry and persists it, allowing a configured command, arguments, environment, or URL to run through the agent platform. - **Rationale:** This is a real AI-agent configuration capability whose exact caller and consent flow are obscured by the bundled code. There is no inspected evidence of an install hook, credential theft, remote payload download, or automatic configuration mutation. - **Files touched:** .claude.json ### Review decision - **Verdict:** Suspicious - **Confidence:** 84.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** The manifest scripts shown are build commands, with no install lifecycle hook in the inspected section., The MCP bundle accepts apply and approval-related command-line options., The MCP bundle reads an MCP configuration and adds a server entry containing a command, arguments, optional environment, and optional URL., The MCP bundle writes the resulting configuration to disk. ## Affected versions and remediation This report applies to @whalent/agent@0.3.477. - Review the evidence and your use of @whalent/agent@0.3.477 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. ## Public findings ### 1.
