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:** 0.2.75 - **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 source shows no install lifecycle trigger or runtime self-dependency, and the reviewed network and data handling are bounded to local browser control and paired-agent telemetry. The scanner signals are consistent with the package’s advertised local device runtime behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 92.0% - **Started:** 2026-10-09T06:01:09.959Z - **Finished:** 2026-10-09T06:01:33.225Z - **Download time:** 1545 ms - **Static scan time:** 1072 ms - **AI review time:** 20648 ms - **Total time:** 23266 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 malicious attack surface was identified. The package provides a local MCP runtime with browser control, document reads, and usage telemetry. - **Trigger:** The user or paired ReMCP agent starts the CLI and invokes its runtime tools. - **Impact:** No confirmed unauthorized mutation, credential exposure, or external exfiltration was established from the inspected source. - **Review source:** ai\_review - **Reviewed:** 2026-10-09T06:01:33.225Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Browser requests are limited to loopback CDP endpoints; telemetry is field-whitelisted and forwarded through the paired agent; document reads use the safe-path resolver. - **Rationale:** The source shows no install lifecycle trigger or runtime self-dependency, and the reviewed network and data handling are bounded to local browser control and paired-agent telemetry. The scanner signals are consistent with the package’s advertised local device runtime behavior. - **Files touched:** src/extended/documents.mjs - **Network endpoints:** http://127.0.0.1:9222 ### Review decision - **Verdict:** Clean - **Confidence:** 92.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json exposes a CLI and ordinary runtime scripts, with no install lifecycle hook or self-dependency., The browser client restricts CDP endpoints to loopback hosts before making requests., Telemetry whitelists event fields and sends through the paired runtime agent., Document reads resolve paths through the runtime safe-path helper. ## Affected versions and remediation This report applies to @remcp/runtime@0.2.75. - Review the evidence and your use of @remcp/runtime@0.2.75 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.
