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:** 0.3.462 - **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 trigger, so blocking is not supported. Its runtime configuration injection capability is a real AI-agent control-surface risk and is best treated as user-invoked capability abuse. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 82.0% - **Started:** 2026-09-23T09:59:43.216Z - **Finished:** 2026-09-23T10:01:26.634Z - **Download time:** 2033 ms - **Static scan time:** 2155 ms - **AI review time:** 99229 ms - **Total time:** 103418 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 includes a runtime capability to modify MCP configuration. No automatic install-time attack surface was identified. - **Trigger:** A user runs the MCP or CLI functionality and invokes its configuration-management behavior. - **Impact:** A user-invoked operation can alter an AI-agent MCP configuration; static inspection found no install-time activation. - **Evidence paths:** dist/mcp.cjs - **Review source:** ai\_review - **Reviewed:** 2026-09-23T10:01:26.634Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The bundled routine creates a config.toml path and injects an MCP server entry. - **Rationale:** The package has no install lifecycle trigger, so blocking is not supported. Its runtime configuration injection capability is a real AI-agent control-surface risk and is best treated as user-invoked capability abuse. - **Files touched:** config.toml ### 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 exposes a CLI but contains no npm lifecycle hook., The MCP bundle contains a routine that constructs a config.toml path and updates MCP-server configuration., MCP execution is gated by direct runtime invocation, rather than package installation. - **Evidence against:** No preinstall, install, postinstall, or self-dependency is declared. ## Affected versions and remediation This report applies to @whalent/agent-core@0.3.462. - Review the evidence and your use of @whalent/agent-core@0.3.462 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.
