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:** 0.2.152 - **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. The inspected source supports the package’s stated local runtime behavior. The flagged dynamic import is conditional on Wayland, while telemetry is filtered and sent through the paired runtime channel; no concrete attack behavior was established. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-16T18:38:25.889Z - **Finished:** 2026-10-16T18:40:17.305Z - **Download time:** 1531 ms - **Static scan time:** 1386 ms - **AI review time:** 108498 ms - **Total time:** 111416 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 package source. The flagged dependency import and document handlers support the runtime’s local desktop and file tools. - **Trigger:** Starting the runtime or invoking one of its named tools. - **Impact:** No confirmed attack impact; the inspected behaviors are consistent with the package’s local runtime functionality. - **Review source:** ai\_review - **Reviewed:** 2026-10-16T18:40:17.305Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The runtime serves local tools over MCP; the inspected telemetry path filters event fields and forwards them through the active runtime server. - **Rationale:** The inspected source supports the package’s stated local runtime behavior. The flagged dynamic import is conditional on Wayland, while telemetry is filtered and sent through the paired runtime channel; no concrete attack behavior was established. ### 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 start, check, and test scripts, exposes src/index.mjs as the binary, and identifies the ReMCP runtime repository., Telemetry supports explicit opt-out, filters event fields through a whitelist, and sends its payload through the active runtime server notification., Tool invocation records the tool name, duration, and success status without recording tool arguments in that event., The flagged dynamic dependency import is Wayland-gated and queries GNOME Mutter display state., Document editing is exposed as a named runtime tool and resolves the requested file path before operating on it. ## Affected versions and remediation This report applies to @remcp/runtime@0.2.152. - Review the evidence and your use of @remcp/runtime@0.2.152 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.
