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:** 0.2.103 - **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 manifest has no install hook, and the required source paths show caller-invoked document handling and optional local desktop DBus inventory. The scanner signals do not establish an active attack. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 86.0% - **Started:** 2026-10-09T06:00:02.436Z - **Finished:** 2026-10-09T06:00:51.435Z - **Download time:** 511 ms - **Static scan time:** 1179 ms - **AI review time:** 47308 ms - **Total time:** 48999 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:** The inspected source exposes local document and desktop runtime functions. No malicious attack surface was identified in the required source paths. - **Trigger:** The user or paired runtime invokes a document action or starts desktop inventory in a Wayland session. - **Impact:** No malicious impact was established from the inspected behavior. - **Review source:** ai\_review - **Reviewed:** 2026-10-09T06:00:51.435Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Document actions select an operation and resolve the caller-supplied path; optional DBus access is limited to desktop inventory in a Wayland session. - **Rationale:** The inspected manifest has no install hook, and the required source paths show caller-invoked document handling and optional local desktop DBus inventory. The scanner signals do not establish an active attack. ### Review decision - **Verdict:** Clean - **Confidence:** 86.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json lists ordinary start, check, and test scripts and declares the optional desktop DBus dependency; it has no install lifecycle hook., The Linux desktop module loads DBus only in a Wayland session and returns if the optional dependency is unavailable., Document PDF actions are explicitly selected by the caller and resolve the input path before reading it. ## Affected versions and remediation This report applies to @remcp/runtime@0.2.103. - Review the evidence and your use of @remcp/runtime@0.2.103 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 L1291: let dbus; L1292: try { dbus = await import('@jellybrick/dbus-next'); } catch { return null; } L1293: const bus = dbus.sessionBus(); ``` ### 6.

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:** 86.0% - **Path:** package.json - **Public source:** [View source]() package.json lists ordinary start, check, and test scripts and declares the optional desktop DBus dependency; it has no install lifecycle hook. Public source snippet (untrusted): ```json "scripts": { "start": "node src/index.mjs", "check": "node scripts/check.mjs", "test": "node --test test/*.test.mjs" }, "dependencies": { "@jellybrick/dbus-next": "^0.11.3", "@modelcontextprotocol/server": "^2.0.0" }, "devDependencies": { "@modelcontextprotocol/client": "^2.0.0" }, ``` ### 12. Low: Suspicious Dependency Evidence - **Category:** Dependency - **Confidence:** 86.0% - **Path:** src/extended/desktop-linux.mjs - **Public source:** [View source]() The Linux desktop module loads DBus only in a Wayland session and returns if the optional dependency is unavailable. 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 ``` ## 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:** 0.2.103 - **License:** MIT - **Version published:** 2026-09-22T15:37:59.141Z - **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:** 713,908 bytes - **Artifact signatures:** 2 - **Attestations:** Yes - **Provenance:** https://slsa.dev/provenance/v1 ## References - [HTML security report]() - [Repository]() - [Homepage]() - [Issues]()
