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:** 0.2.105 - **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-time execution or concrete attack behavior. The scanner’s network, environment, and dependency-bridge signals match the package’s local browser and Linux desktop runtime features. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 93.0% - **Started:** 2026-10-09T06:00:04.398Z - **Finished:** 2026-10-09T06:00:29.107Z - **Download time:** 1282 ms - **Static scan time:** 1162 ms - **AI review time:** 22264 ms - **Total time:** 24709 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 runtime exposes local device and document tools, and its browser CDP requests are restricted to loopback. - **Trigger:** A user or MCP client starts the published remcp-runtime executable and invokes its tools. - **Impact:** No confirmed malicious effect or external credential exposure was established. - **Review source:** ai\_review - **Reviewed:** 2026-10-09T06:00:29.107Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The inspected Linux bridge queries the local Mutter display interface; browser discovery validates loopback endpoints; document operations use filesystem APIs and safe-path resolution. - **Rationale:** Source inspection found no install-time execution or concrete attack behavior. The scanner’s network, environment, and dependency-bridge signals match the package’s local browser and Linux desktop runtime features. - **Files touched:** src/extended/documents.mjs - **Network endpoints:** 127.0.0.1 ### Review decision - **Verdict:** Clean - **Confidence:** 93.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json declares a local runtime executable and has no install lifecycle hook., Linux display support imports its declared D-Bus dependency to query Mutter display state., Browser CDP endpoint validation restricts requests to loopback hosts., Document editing imports filesystem helpers and safe-path resolution; no network behavior was identified in the inspected source. ## Affected versions and remediation This report applies to @remcp/runtime@0.2.105. - Review the evidence and your use of @remcp/runtime@0.2.105 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 = 3 ``` ### 11. Low: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 93.0% - **Path:** package.json - **Public source:** [View source]() package.json declares a local runtime executable and has no install lifecycle hook.
