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:** 0.2.194 - **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 flagged files implement desktop capture and system information or process tools consistent with the package’s purpose. No install-time contact or concealed unrelated behavior was found; telemetry is limited to usage metadata and can be disabled. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 94.0% - **Started:** 2026-10-29T06:11:46.073Z - **Finished:** 2026-10-29T06:12:21.388Z - **Download time:** 504 ms - **Static scan time:** 1570 ms - **AI review time:** 33240 ms - **Total time:** 35315 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 source matches a local MCP runtime for device, desktop and filesystem tools. - **Trigger:** The runtime starts when invoked; local actions occur when its MCP tools are called. - **Impact:** No malicious impact identified. Local tools can perform consequential actions when requested, and telemetry is opt-out. - **Review source:** ai\_review - **Reviewed:** 2026-10-29T06:12:21.388Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** It serves MCP over stdio, uses D-Bus for requested desktop capture, and forwards whitelisted usage telemetry through an MCP notification. - **Rationale:** The flagged files implement desktop capture and system information or process tools consistent with the package’s purpose. No install-time contact or concealed unrelated behavior was found; telemetry is limited to usage metadata and can be disabled. ### 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 defines start, check and test scripts, with no install lifecycle hooks., Telemetry restricts event fields to tool names, timings, outcomes and coarse error classes; it excludes paths, commands, arguments and output., Telemetry is forwarded as an MCP notification by the runtime server., Screenshot portal code loads D-Bus when capture is requested, matching the package’s desktop capture purpose., Process termination requires a supplied PID and refuses to terminate protected or runtime-related processes. - **Evidence against:** Telemetry is enabled by default unless disabled, and includes runtime and tool-use metadata., The runtime exposes powerful local capabilities, including process termination, when invoked through its tools. ## Affected versions and remediation This report applies to @remcp/runtime@0.2.194. - Review the evidence and your use of @remcp/runtime@0.2.194 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.

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 = 0.854 summary = stored previous version shares package body but lacks this dangerous source file ``` ### 12. Low: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 94.0% - **Path:** package.json - **Public source:** [View source]() The package defines start, check and test scripts, with no install lifecycle hooks.
