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:** 0.2.36 - **Selected version is latest:** Yes - **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. Source inspection confirms automatic, guarded setup of this package’s own MCP integration in detected agent configurations. Under the agent integration policy, this warrants a warning for first-party extension setup, but the inspected behavior does not establish malicious intent. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-07T23:04:11.287Z - **Finished:** 2026-10-07T23:04:36.723Z - **Download time:** 506 ms - **Static scan time:** 360 ms - **AI review time:** 24568 ms - **Total time:** 25436 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 npm postinstall automatically attempts to register brokre as an MCP server in detected agent and IDE configuration. This is first-party package setup, but it modifies agent configuration without an explicit setup command. - **Trigger:** Installing the package with its postinstall script enabled, outside CI and without the opt-out variable. - **Impact:** The detected tools may automatically make brokre’s MCP server available after installation. - **Evidence paths:** package.json, postinstall.js, setup-mcp.js - **Review source:** ai\_review - **Reviewed:** 2026-10-07T23:04:36.723Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The postinstall launches setup-mcp.js, which detects installed tools and adds the brokre MCP entry to their configuration. - **Rationale:** Source inspection confirms automatic, guarded setup of this package’s own MCP integration in detected agent configurations. Under the agent integration policy, this warrants a warning for first-party extension setup, but the inspected behavior does not establish malicious intent. - **Files touched:** setup-mcp.js, postinstall.js, package.json ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** package.json runs postinstall.js automatically during installation., postinstall.js invokes setup-mcp.js with the inherited environment., setup-mcp.js detects existing agent configuration, including Codex history and session files., The setup registers brokre for detected IDEs and writes changed configuration files., Automatic setup can be skipped with BROKRE\_MCP\_SKIP\_SETUP=1 or in CI. - **Evidence against:** The installer registers this package’s own MCP server rather than a foreign extension., The setup writes only when changes are needed and preserves backups of existing configuration files. ## Affected versions and remediation This report applies to brokre@0.2.36. - Review the evidence and your use of brokre@0.2.36 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.
