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:** 0.2.186 - **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 hook or concrete attack behavior. The flagged dependency and runtime operations are consistent with desktop screenshot capture, MCP transport, and configured telemetry sent through the paired runtime connection. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 94.0% - **Started:** 2026-10-29T06:10:45.035Z - **Finished:** 2026-10-29T06:15:11.693Z - **Download time:** 1016 ms - **Static scan time:** 1562 ms - **AI review time:** 264079 ms - **Total time:** 266658 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 sources. The flagged network and process primitives support local MCP and desktop screenshot features. - **Trigger:** The runtime starts through its declared CLI entry point; screenshot capture is invoked when requested on Linux Wayland. - **Impact:** The inspected behavior provides local device tools and event notifications; no unrelated credential transfer or installation-time action was identified. - **Review source:** ai\_review - **Reviewed:** 2026-10-29T06:15:11.693Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** It communicates with its MCP client over standard input and output and requests screenshots through the desktop portal using session D-Bus. - **Rationale:** Source inspection found no install hook or concrete attack behavior. The flagged dependency and runtime operations are consistent with desktop screenshot capture, MCP transport, and configured telemetry sent through the paired runtime connection. ### Review decision - **Verdict:** Clean - **Confidence:** 94.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The manifest declares a CLI entry point and regular start, check, and test scripts; it has no install lifecycle hook., On Linux Wayland, the screenshot tool calls the desktop portal helper for a capture; that helper loads the declared D-Bus dependency for the request., The file write tool resolves the caller-supplied path before using its content., The bundled MCP listener forwards accepted subscription events as notifications, and the server package provides a stdio transport., Telemetry is sent as an MCP notification through the runtime server, uses whitelisted event fields, and can be disabled by configuration. ## Affected versions and remediation This report applies to @remcp/runtime@0.2.186. - Review the evidence and your use of @remcp/runtime@0.2.186 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.

Low: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 94.0% - **Path:** package.json - **Public source:** [View source]() The manifest declares a CLI entry point and regular start, check, and test scripts; it has no install lifecycle hook.

Low: Suspicious Dependency Evidence - **Category:** Dependency - **Confidence:** 94.0% - **Path:** src/tools/files-screenshots.mjs - **Public source:** [View source]() On Linux Wayland, the screenshot tool calls the desktop portal helper for a capture; that helper loads the declared D-Bus dependency for the request.
