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:** 0.2.102 - **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 inspected findings are explained by package-aligned runtime functions, and the browser endpoint is loopback-restricted. The manifest shows no install lifecycle hook or runtime self-dependency, so the scanner signals do not establish malicious behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 93.0% - **Started:** 2026-10-09T05:59:55.923Z - **Finished:** 2026-10-09T06:00:22.213Z - **Download time:** 510 ms - **Static scan time:** 1118 ms - **AI review time:** 24661 ms - **Total time:** 26290 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 source. The flagged dependency bridge and network use fit the runtime’s display and browser-control functions. - **Trigger:** Runtime use of display inventory, document tools, or browser-control tools. - **Impact:** No malicious effect was established from these behaviors. - **Review source:** ai\_review - **Reviewed:** 2026-10-09T06:00:22.213Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Display inventory conditionally queries the local D-Bus session; document extraction validates archive paths; browser control restricts endpoints to loopback. - **Rationale:** The inspected findings are explained by package-aligned runtime functions, and the browser endpoint is loopback-restricted. The manifest shows no install lifecycle hook or runtime self-dependency, so the scanner signals do not establish malicious behavior. ### 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 defines start, check, and test scripts; it has no install lifecycle script, and its runtime dependencies do not include itself., The Linux display code conditionally imports the declared D-Bus dependency only in a Wayland session to query display state., Document archive entries are checked for absolute paths and traversal before extraction., Browser control accepts only HTTP(S) endpoints and restricts them to loopback hosts. ## Affected versions and remediation This report applies to @remcp/runtime@0.2.102. - Review the evidence and your use of @remcp/runtime@0.2.102 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.

High: Copied Package Dependency Bridge - **Category:** Source - **Confidence:** 83.0% - **Path:** src/extended/desktop-linux.mjs - **Public source:** [View source]() Package metadata claims a different repository identity while copied source loads a runtime dependency bridge. Public source snippet (untrusted): ```javascript package = @remcp/runtime; repositoryIdentity = remcp; dependency = @jellybrick/dbus-next L1205: let dbus; L1206: try { dbus = await import('@jellybrick/dbus-next'); } catch { return null; } L1207: const bus = dbus.sessionBus(); ``` ### 6. Low: High Entropy Strings - **Category:** Supply Chain - **Confidence:** 55.0% Package source contains high-entropy string patterns. ### 7. Low: Url Strings - **Category:** Supply Chain - **Confidence:** 65.0% Package source contains URL literals. ### 8. Medium: Ships Build Helper - **Category:** Artifact Inventory - **Confidence:** 70.0% - **Path:** src/helpers/wayland-eis-helper.py - **Public source:** [View source]() Package ships non-JavaScript build or shell helper files. Public source snippet (untrusted): ```python path = src/helpers/wayland-eis-helper.py kind = build_helper sizeBytes = 20492 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/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 defines start, check, and test scripts; it has no install lifecycle script, and its runtime dependencies do not include itself. Public source snippet (untrusted): ```json "scripts": { "start": "node src/index.mjs", "check": "node scripts/check.mjs", "test": "node --test test/*.test.mjs" }, "dependencies": { "@jellybri ``` ### 12. Low: Suspicious Dependency Evidence - **Category:** Dependency - **Confidence:** 93.0% - **Path:** src/extended/desktop-linux.mjs - **Public source:** [View source]() The Linux display code conditionally imports the declared D-Bus dependency only in a Wayland session to query display state. Public source snippet (untrusted): ```javascript async function mutterDisplayInventory() { if (!isWaylandSession()) return null; let dbus; try { dbus = await import('@jellybrick/dbus-next'); } catch { return null; } const bus = dbu ``` ## Dependencies and install lifecycle - **Lifecycle scripts present:** No - **Dependencies:** 2 - **Optional dependencies:** 0 - **Peer dependencies:** 0 - **Development dependencies:** 1 - **Published dependency-graph edges:** 2 ### Published dependency entries - @jellybrick/dbus-next ^0.11.3 (Dependency) - @modelcontextprotocol/server ^2.0.0 (Dependency) ## Package metadata - **Package:** @remcp/runtime - **Ecosystem:** npm - **Version:** 0.2.102 - **License:** MIT - **Version published:** 2026-09-22T13:10:15.240Z - **Package first seen:** 2026-09-17T00:07:21.569Z - **Package last seen:** 2026-11-04T12:55:17.605Z - **Known versions:** 123 - **Latest version:** 0.2.230 - **Appeal under review:** No - **Description:** First-party ReMCP local device runtime: filesystem, terminal, computer-use, browser, diagnostics and document tools over MCP. - **Author:** Anton Baider - **Maintainers:** antonbaider - **Keywords:** mcp, model-context-protocol, remcp, remote, terminal, filesystem, self-hosted - **Runtime engines:** node: \>=22.5.0 - **Artifact files:** 40 - **Artifact unpacked size:** 709,386 bytes - **Artifact signatures:** 2 - **Attestations:** Yes - **Provenance:** https://slsa.dev/provenance/v1 ## References - [HTML security report]() - [Repository]() - [Homepage]() - [Issues]()
