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:** 0.3.471 - **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 source establishes a concrete agent-control capability that writes command-bearing MCP entries, but does not establish install-time execution, credential theft, or a payload attack. This warrants a warning for explicit agent configuration mutation. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 90.0% - **Started:** 2026-09-28T05:14:03.458Z - **Finished:** 2026-09-28T05:15:18.002Z - **Download time:** 770 ms - **Static scan time:** 1562 ms - **AI review time:** 72211 ms - **Total time:** 74544 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 service can register an arbitrary command as an MCP server in agent configuration. No automatic install-time attack was identified. - **Trigger:** A caller invokes the MCP management register action. - **Impact:** A permitted caller or compromised agent session could persist a command that an agent platform may later execute. - **Evidence paths:** dist/mcp.cjs - **Review source:** ai\_review - **Reviewed:** 2026-09-28T05:15:18.002Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The action forwards caller-provided command, arguments, and environment to the MCP-server injection routine, which writes an agent server entry. - **Rationale:** The source establishes a concrete agent-control capability that writes command-bearing MCP entries, but does not establish install-time execution, credential theft, or a payload attack. This warrants a warning for explicit agent configuration mutation. - **Files touched:** .claude.json ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** The package declares a command-line core entry point and distributes the MCP bundle., The MCP bundle accepts a requested server name, command, arguments, and environment, then registers that server in an agent configuration., The bundle includes logic that adds a server definition to Claude configuration. - **Evidence against:** No npm lifecycle hook is declared in the inspected package metadata., The configuration mutation is reached through an MCP management action rather than an install hook. ## Affected versions and remediation This report applies to @whalent/agent-core@0.3.471. - Review the evidence and your use of @whalent/agent-core@0.3.471 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.
