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:** 0.2.113 - **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 contains no install hook, and inspected flagged code supports the package’s local runtime functions. Telemetry is opt-out, but the inspected code limits event fields and sends through the paired MCP connection; 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:** 2026-10-09T06:00:21.008Z - **Finished:** 2026-10-09T06:00:43.062Z - **Download time:** 510 ms - **Static scan time:** 1168 ms - **AI review time:** 20375 ms - **Total time:** 22054 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 import supports Wayland display inventory, and telemetry uses the paired MCP connection. - **Trigger:** Runtime startup enables telemetry unless disabled; desktop inventory is invoked during runtime use on Wayland. - **Impact:** No confirmed malicious effect or unapproved external destination was established. - **Review source:** ai\_review - **Reviewed:** 2026-10-09T06:00:43.062Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Telemetry events use whitelisted fields and are sent as an MCP notification. The desktop module conditionally imports the declared D-Bus dependency to query display state. - **Rationale:** The manifest contains no install hook, and inspected flagged code supports the package’s local runtime functions. Telemetry is opt-out, but the inspected code limits event fields and sends through the paired MCP connection; 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 has no install lifecycle hook and starts the declared CLI entry point., The Linux desktop module loads its declared D-Bus dependency only for Wayland display inventory., Document handling opens a caller-selected path as a regular file., Telemetry is sent through the MCP server notification sink, and its event fields are whitelisted. ## Affected versions and remediation This report applies to @remcp/runtime@0.2.113. - Review the evidence and your use of @remcp/runtime@0.2.113 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.

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 has no install lifecycle hook and starts the declared CLI entry point.

Low: Suspicious Dependency Evidence - **Category:** Dependency - **Confidence:** 94.0% - **Path:** src/extended/desktop-linux.mjs - **Public source:** [View source]() The Linux desktop module loads its declared D-Bus dependency only for Wayland display inventory. 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:** 0.2.113 - **License:** MIT - **Version published:** 2026-09-26T05:59:23.779Z - **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:** 822,984 bytes - **Artifact signatures:** 2 - **Attestations:** Yes - **Provenance:** https://slsa.dev/provenance/v1 ## References - [HTML security report]() - [Repository]() - [Homepage]() - [Issues]()
