Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Flagged as agent extension risk** — Allowed by default with warning: install-time first-party agent extension setup was detected. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Warn-only agent extension risk - **Public report status:** Published - **Threat category:** Agent extension lifecycle risk - **Selected version:** 0.3.463 - **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. The package has no install lifecycle hook, but its MCP daemon includes active AI-agent configuration primitives with broad caller-supplied settings. Static inspection did not prove an automatic or malicious activation path. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 82.0% - **Started:** 2026-09-28T02:37:30.042Z - **Finished:** 2026-09-28T02:42:36.288Z - **Download time:** 1015 ms - **Static scan time:** 1580 ms - **AI review time:** 303650 ms - **Total time:** 306246 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 MCP daemon contains agent-configuration functionality that can create MCP server entries for supported AI-agent clients. No automatic install-time attack surface was identified. - **Trigger:** A caller must start the MCP daemon and invoke its exposed tool functionality. - **Impact:** A permitted caller could alter an AI-agent MCP configuration; no confirmed unconsented activation or credential export was established. - **Evidence paths:** dist/mcp.cjs - **Review source:** ai\_review - **Reviewed:** 2026-09-28T02:42:36.288Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The bundle selects agent configuration directories and writes caller-supplied MCP command, arguments, environment, or URL settings. - **Rationale:** The package has no install lifecycle hook, but its MCP daemon includes active AI-agent configuration primitives with broad caller-supplied settings. Static inspection did not prove an automatic or malicious activation path. - **Files touched:** .claude.json ### Review decision - **Verdict:** Suspicious - **Confidence:** 82.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The manifest contains build and publish scripts but no automatic install lifecycle hook., The MCP bundle selects Claude, Cursor, or generic agent directories under the user home directory., The MCP bundle constructs Claude MCP server entries with caller-provided command, arguments, environment, or URL fields, then writes configuration., The daemon exposes MCP tool-call handling, so its configuration capability is an active service feature rather than package-install behavior. - **Evidence against:** No automatic npm install trigger was found in the manifest., No confirmed secret export, destructive action, or unconsented configuration write was traced from package installation. ## Affected versions and remediation This report applies to @whalent/agent@0.3.463. - Review the evidence and your use of @whalent/agent@0.3.463 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.
