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:** 0.2.147 - **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 manifest has no install hook, and the inspected runtime behavior is exposed as caller-invoked local tools. Scanner-flagged display and document code serves those functions; no concrete attack behavior was found. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 94.0% - **Started:** 2026-10-14T10:25:57.286Z - **Finished:** 2026-10-14T10:28:23.474Z - **Download time:** 1269 ms - **Static scan time:** 1358 ms - **AI review time:** 143560 ms - **Total time:** 146188 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 package provides local computer and document tools through an MCP runtime. - **Trigger:** The runtime starts through its executable; individual operations run when a caller invokes the corresponding tool. - **Impact:** No harmful effect was established; the inspected behavior matches the package’s local runtime function. - **Review source:** ai\_review - **Reviewed:** 2026-10-14T10:28:23.474Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Local operations use caller-supplied tool arguments. Browser CDP control is restricted to a loopback endpoint, and telemetry is forwarded through the paired agent. - **Rationale:** The manifest has no install hook, and the inspected runtime behavior is exposed as caller-invoked local tools. Scanner-flagged display and document code serves those functions; no concrete attack behavior was found. ### Review decision - **Verdict:** Clean - **Confidence:** 94.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json lists start, check, and test scripts; it has no install lifecycle hook., The runtime exposes local tools through caller-invoked MCP handlers and says changes should occur only when the user asked for them., Browser control requires a loopback CDP endpoint., Telemetry is opt-out, limits event details, and travels through the paired agent; its payload also includes runtime metadata., The flagged Linux helper queries GNOME display state through D-Bus, while document operations resolve caller-provided paths. ## Affected versions and remediation This report applies to @remcp/runtime@0.2.147. - Review the evidence and your use of @remcp/runtime@0.2.147 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-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 = 23624 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 = 2 ``` ### 11. Low: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 94.0% - **Path:** package.json - **Public source:** [View source]() package.json lists start, check, and test scripts; it has no install lifecycle hook. Public source snippet (untrusted): ```json "scripts": { "start": "node src/index.mjs", "check": "node scripts/check.mjs", "test": "node --import ./test/setup.mjs --test test/*.test.mjs" }, "dependencies": ``` ### 12. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 94.0% - **Path:** src/index.mjs - **Public source:** [View source]() The runtime exposes local tools through caller-invoked MCP handlers and says changes should occur only when the user asked for them. Public source snippet (untrusted): ```javascript const runtimeInstructions = [ 'This runtime executes file, search, terminal, process, desktop UI, browser, diagnostics, and document tools locally on a computer its owner paired with ReMCP.', 'Inspect before changing: read, snapshot, list or find first; then write, edit, click, move, launch, or run commands only when the user asked for that side effect.' ``` ## 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:** 0.2.147 - **License:** MIT - **Version published:** 2026-10-14T05:47:34.996Z - **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:** 891,493 bytes - **Artifact signatures:** 2 - **Attestations:** Yes - **Provenance:** https://slsa.dev/provenance/v1 ## References - [HTML security report]() - [Repository]() - [Homepage]() - [Issues]()
