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:** 0.2.183 - **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 scanner flags resolve to ordinary runtime functionality: the package has no install hook, the dependency bridge loads a D-Bus client for local portal use, and the flagged MCP code filters and forwards protocol events. The inspected source does not establish a concrete attack. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 94.0% - **Started:** 2026-10-25T16:02:39.904Z - **Finished:** 2026-10-25T16:03:57.588Z - **Download time:** 1273 ms - **Static scan time:** 1480 ms - **AI review time:** 74930 ms - **Total time:** 77684 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 surface was identified in the inspected source. The flagged dependency bridge resolves to ordinary MCP and desktop portal functionality. - **Trigger:** Runtime tools activate through the paired agent; screenshot capture runs when its tool is invoked. - **Impact:** No unrequested credential transfer, installation mutation, or other concrete attack behavior was identified. - **Review source:** ai\_review - **Reviewed:** 2026-10-25T16:03:57.588Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The inspected code handles MCP notifications, caller-supplied file operations, and local desktop screenshot requests. - **Rationale:** The scanner flags resolve to ordinary runtime functionality: the package has no install hook, the dependency bridge loads a D-Bus client for local portal use, and the flagged MCP code filters and forwards protocol events. The inspected source does not establish a concrete attack. ### Review decision - **Verdict:** Clean - **Confidence:** 94.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json exposes a CLI and lists runtime dependencies; its scripts contain no install lifecycle hook., The inspected dependency manifests contain no install lifecycle hooks, and the MCP server source implements filtered event subscriptions and stdio transport., Screenshot capture is invoked through the screenshot tool and uses the local desktop portal or platform screenshot commands., The D-Bus dependency exposes session-bus APIs used by the portal screenshot flow., File writes use a caller-supplied path resolved through the runtime's safe-path helper. ## Affected versions and remediation This report applies to @remcp/runtime@0.2.183. - Review the evidence and your use of @remcp/runtime@0.2.183 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.
