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:** 0.2.182 - **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 manifest has no install hook, and the inspected runtime and dependency paths match local MCP, file, and desktop functions. Static signals such as shell and network APIs did not establish malicious behavior in these paths. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 94.0% - **Started:** 2026-10-25T12:42:25.145Z - **Finished:** 2026-10-25T12:43:32.262Z - **Download time:** 520 ms - **Static scan time:** 1458 ms - **AI review time:** 65138 ms - **Total time:** 67117 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 executable entrypoint starts a local MCP runtime whose reviewed file and desktop operations are exposed as tools. - **Trigger:** Starting the runtime enables its MCP tools; file changes or screenshots occur when a tool is invoked. - **Impact:** No malicious effect was established; these paths provide the advertised local device functions. - **Review source:** ai\_review - **Reviewed:** 2026-10-25T12:43:32.262Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The runtime passes tool arguments to local file operations or the desktop portal. The inspected dependency router filters events before forwarding them. - **Rationale:** The manifest has no install hook, and the inspected runtime and dependency paths match local MCP, file, and desktop functions. Static signals such as shell and network APIs did not establish malicious behavior in these paths. - **Files touched:** package.json, src/index.mjs, src/tools/files-screenshots.mjs, src/tools/files-write-edit.mjs, src/screenshot-portal.mjs, .lpm-dependency-evidence-f799cdc7-251d-430e-baaf-85d128855a52/0/npm-linux/package.json, .lpm-dependency-evidence-f799cdc7-251d-430e-baaf-85d128855a52/0/npm-linux/dist/index.mjs, .lpm-dependency-evidence-f799cdc7-251d-430e-baaf-85d128855a52/1/npm-linux/package.json, .lpm-dependency-evidence-f799cdc7-251d-430e-baaf-85d128855a52/1/npm-linux/dist/index.mjs, .lpm-dependency-evidence-f799cdc7-251d-430e-baaf-85d128855a52/1/npm-linux/dist/stdio.mjs, .lpm-dependency-evidence-f799cdc7-251d-430e-baaf-85d128855a52/1/npm-linux/dist/listenRouter-Bartj63y.mjs ### 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 manifest has no install lifecycle hook; it declares start, check, and test scripts and the two reviewed runtime dependencies., The desktop capture code uses the session D-Bus desktop portal, and the inspected D-Bus dependency exposes a session-bus client., The MCP server dependency is used with stdio transport, which reads process stdin and writes process stdout., Screenshot capture is exposed as a tool taking caller arguments; the portal result must be a local file URI before it is copied to the destination., File writes use caller-supplied path and content through the runtime safe-path resolver., The inspected SDK router filters subscribed events before forwarding notifications. ## Affected versions and remediation This report applies to @remcp/runtime@0.2.182. - Review the evidence and your use of @remcp/runtime@0.2.182 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.
