Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Allowed — no malicious behavior detected** — No malicious behavior detected. 12 low-signal pattern(s) reviewed. - **Verdict:** Clean - **Product-default install policy:** Allow - **Firewall policy:** No policy match - **Public report status:** Published - **Threat category:** None published - **Selected version:** 0.2.144 - **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: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. Source inspection found no install lifecycle hook or concrete malicious behavior. The flagged D-Bus import is an optional display-state lookup, while the reviewed browser and document operations enforce local destination and path controls. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-09T06:01:35.505Z - **Finished:** 2026-10-09T06:02:12.301Z - **Download time:** 773 ms - **Static scan time:** 1347 ms - **AI review time:** 34675 ms - **Total time:** 36796 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:** No attack was identified in the inspected source. The reviewed network and file operations are tied to local runtime functions and bounded destinations. - **Trigger:** The executable starts when invoked as the runtime; browser and document behavior is invoked through its MCP tools. - **Impact:** No confirmed malicious impact or attack surface was established. - **Review source:** ai\_review - **Reviewed:** 2026-10-09T06:02:12.301Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** No install-time action was found; the reviewed browser endpoint check requires loopback, and document edits use the safe-path resolver. - **Rationale:** Source inspection found no install lifecycle hook or concrete malicious behavior. The flagged D-Bus import is an optional display-state lookup, while the reviewed browser and document operations enforce local destination and path controls. ### Review decision - **Verdict:** Clean - **Confidence:** 91.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json defines no preinstall, install, or postinstall hook., The Linux D-Bus bridge is optional and reads the current Wayland display state., Document edits resolve their input through the runtime's safe-path helper., Browser CDP endpoints are restricted to loopback hosts. ## Affected versions and remediation This report applies to @remcp/runtime@0.2.144. - Review the evidence and your use of @remcp/runtime@0.2.144 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.
