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:** 0.2.191 - **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 hook, unrelated network recipient, or unrequested account or control-surface action. The scanner flags correspond to the package's declared local runtime capabilities and SDK code, not demonstrated malicious behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 95.0% - **Started:** 2026-10-29T06:11:31.735Z - **Finished:** 2026-10-29T06:12:37.675Z - **Download time:** 758 ms - **Static scan time:** 1594 ms - **AI review time:** 63586 ms - **Total time:** 65940 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 behavior was identified. The package provides a local device runtime whose tools operate through its MCP interface. - **Trigger:** Starting the runtime; individual local operations are requested through MCP. - **Impact:** No package-directed attack impact was established from the inspected source. - **Review source:** ai\_review - **Reviewed:** 2026-10-29T06:12:37.675Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The entry point starts an MCP stdio server. Runtime tools perform local file, screenshot, and system operations, while usage events are forwarded through the paired server. - **Rationale:** Source inspection found no install hook, unrelated network recipient, or unrequested account or control-surface action. The scanner flags correspond to the package's declared local runtime capabilities and SDK code, not demonstrated malicious behavior. ### Review decision - **Verdict:** Clean - **Confidence:** 95.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The manifest defines a CLI entry point, ordinary start/check/test scripts, and runtime dependencies; it has no install lifecycle hook., The runtime communicates over MCP stdio. The bundled SDK reads from standard input, writes to standard output, and forwards subscribed protocol notifications., Usage events are sent through the paired runtime server; event fields are restricted to tool names, timings, outcomes, and coarse error categories., The flagged tools perform local operations: screenshots use the desktop portal or available capture utilities, file writes use a supplied path, and system information reads host statistics. ## Affected versions and remediation This report applies to @remcp/runtime@0.2.191. - Review the evidence and your use of @remcp/runtime@0.2.191 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: Ships Build Helper - **Category:** Artifact Inventory - **Confidence:** 70.0% - **Path:** src/helpers/wayland\_eis\_sender.py - **Public source:** [View source]() Package ships non-JavaScript build or shell helper files. Public source snippet (untrusted): ```python path = src/helpers/wayland_eis_sender.py kind = build_helper sizeBytes = 15744 magicHex = [redacted] ``` ### 9. 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/tools/files-screenshots.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. High: Previous Version Dangerous Delta - **Category:** Supply Chain - **Confidence:** 93.0% - **Path:** src/tools/system.mjs - **Public source:** [View source]() This package version adds a dangerous source file absent from the previous stored version; route for source-aware review. Public source snippet (untrusted): ```javascript matchType = previous_version_dangerous_delta matchedPackage = @remcp/runtime@0.2.183 matchedIdentity = npm:QHJlbWNwL3J1bnRpbWU:0.2.183 similarity = 0.865 summary = stored previous version shares package body but lacks this dangerous source file ``` ### 12. Low: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 95.0% - **Path:** package.json - **Public source:** [View source]() The manifest defines a CLI entry point, ordinary start/check/test scripts, and runtime dependencies; it has no install lifecycle hook.
