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:** 0.2.195 - **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 flagged dependency bridge supports Wayland desktop functions, and runtime telemetry is disclosed, bounded to usage metrics, and sent through the paired agent. The source reviewed shows no malicious behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 94.0% - **Started:** 2026-11-01T11:10:36.048Z - **Finished:** 2026-11-01T11:11:09.381Z - **Download time:** 250 ms - **Static scan time:** 1583 ms - **AI review time:** 31498 ms - **Total time:** 33333 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; the package provides a local MCP runtime for ReMCP device tools. - **Trigger:** The runtime starts when invoked by its CLI or paired agent; individual tool actions are requested over MCP. - **Impact:** No malicious collection, unrelated network contact, or unsolicited account action was identified. - **Review source:** ai\_review - **Reviewed:** 2026-11-01T11:11:09.381Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** It performs local device operations and reports limited, disclosed usage metrics through the paired agent. Browser discovery uses the configured loopback CDP endpoint. - **Rationale:** The flagged dependency bridge supports Wayland desktop functions, and runtime telemetry is disclosed, bounded to usage metrics, and sent through the paired agent. The source reviewed shows no malicious behavior. - **Network endpoints:** 127.0.0.1:9222 ### Review decision - **Verdict:** Clean - **Confidence:** 94.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The package exposes a local ReMCP runtime CLI and declares no install lifecycle hooks., Runtime telemetry is disclosed, opt-out, limited to tool names, timings and outcomes, and sent through the paired ReMCP agent., Telemetry filters event fields and excludes file paths, command strings, tool arguments and tool output., The flagged D-Bus dependency is loaded for Wayland screenshot capture, not as an automatic startup bridge. - **Evidence against:** Telemetry is enabled by default, though the package discloses it and provides opt-out controls., The runtime provides powerful local filesystem, process, desktop and browser tools as part of its stated purpose. ## Affected versions and remediation This report applies to @remcp/runtime@0.2.195. - Review the evidence and your use of @remcp/runtime@0.2.195 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.
