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:** 0.2.116 - **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 lifecycle hook or concrete malicious behavior. The scanner's network and execution signals correspond to the local runtime's browser and desktop features, with the browser endpoint restricted to loopback. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-09T06:00:29.789Z - **Finished:** 2026-10-09T06:00:57.806Z - **Download time:** 504 ms - **Static scan time:** 1162 ms - **AI review time:** 26350 ms - **Total time:** 28017 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 inspected process, document, and browser features are runtime capabilities with bounded behavior. - **Trigger:** The runtime starts as a command-line MCP service and performs these features when its tools are invoked. - **Impact:** No confirmed malicious effect or attack surface was established from the inspected source. - **Review source:** ai\_review - **Reviewed:** 2026-10-09T06:00:57.806Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Document access resolves paths through the runtime safe-path function, and browser debugging endpoints are restricted to loopback hosts. - **Rationale:** Source inspection found no install lifecycle hook or concrete malicious behavior. The scanner's network and execution signals correspond to the local runtime's browser and desktop features, with the browser endpoint restricted to loopback. ### 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 no preinstall, install, or postinstall hook; its scripts are start, check, and test., The desktop Linux launch helper passes the selected app and arguments to the launcher as an explicit runtime operation., Document reads resolve the requested path through the runtime safe-path resolver., Browser debugging endpoints require loopback hosts, limiting this network access to a local browser endpoint. ## Affected versions and remediation This report applies to @remcp/runtime@0.2.116. - Review the evidence and your use of @remcp/runtime@0.2.116 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.

Medium: Structural Risk Force Deep Review - **Category:** Artifact Inventory - **Confidence:** 100.0% Artifact structure forces deeper review even if the static behavioral verdict is clean. ### 10. High: Semantic Analysis Limited - **Category:** Scanner Coverage - **Confidence:** 100.0% - **Path:** src/extended/documents.mjs\#virtual:normalized:round1 - **Public source:** [View source]() A bounded semantic-analysis stage reached its safety limit; remaining detectors completed, but this package requires AI review. Public source snippet (untrusted): ```text stage = ast_semantic_analysis; reason = ast_parse_error; limitedFiles = 2 ``` ### 11. Low: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 91.0% - **Path:** package.json - **Public source:** [View source]() package.json defines no preinstall, install, or postinstall hook; its scripts are start, check, and test. Public source snippet (untrusted): ```json "scripts": { "start": "node src/index.mjs", "check": "node scripts/check.mjs", "test": "node --import ./test/setup.mjs --test test/*.test.mjs" }, "dependencies": { "@jellybrick/dbus-next": "^0.11.3", "@modelcontext ``` ### 12. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 91.0% - **Path:** src/extended/desktop-linux.mjs - **Public source:** [View source]() The desktop Linux launch helper passes the selected app and arguments to the launcher as an explicit runtime operation. Public source snippet (untrusted): ```javascript await runFile('notify-send', [optionalString(args.title)||'ReMCP', String(args.message ?? args.body ??
