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:** 0.3.479 - **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. Inspected source establishes runtime agent configuration mutation, which warrants a warning under the supplied policy. It does not establish malicious intent or an unconsented npm installation attack. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 88.0% - **Started:** 2026-09-30T16:27:58.304Z - **Finished:** 2026-09-30T16:30:39.839Z - **Download time:** 1013 ms - **Static scan time:** 1914 ms - **AI review time:** 158607 ms - **Total time:** 161535 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 running MCP server exposes tools that modify agent skills and server configuration. This is a concrete agent control capability, but no confirmed malicious attack was established. - **Trigger:** A caller invokes a management tool on the running MCP server. - **Impact:** Requests can change agent behavior and configure commands that an agent may subsequently launch. - **Evidence paths:** dist/mcp.cjs - **Review source:** ai\_review - **Reviewed:** 2026-09-30T16:30:39.839Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Tool arguments select skill installation or removal and MCP server registration or removal; registration persists command settings in provider configuration. - **Rationale:** Inspected source establishes runtime agent configuration mutation, which warrants a warning under the supplied policy. It does not establish malicious intent or an unconsented npm installation attack. - **Files touched:** .claude.json, config.toml, .cursor ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The package exposes dist/index.cjs as its CLI and has no preinstall, install, or postinstall hook., The MCP request handler dispatches caller-selected tools and arguments to the runtime tool handler., The MCP management tool accepts commands, arguments, and environment settings and registers servers in agent configuration., Claude server registration writes .claude.json; skill management also installs downloaded files into provider-specific directories., The flagged location selects provider directories, including .cursor. - **Evidence against:** No concrete covert exfiltration or malicious installation chain was established., Configuration changes are activated through runtime tool requests rather than npm installation. ## Affected versions and remediation This report applies to @whalent/agent@0.3.479. - Review the evidence and your use of @whalent/agent@0.3.479 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.
