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:** 0.2.66 - **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 reviewed network and file operations are constrained to local endpoints or caller-selected inputs. Static hints alone do not establish malicious behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-09T05:59:09.741Z - **Finished:** 2026-10-09T05:59:32.084Z - **Download time:** 507 ms - **Static scan time:** 1052 ms - **AI review time:** 20782 ms - **Total time:** 22343 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 entrypoint and required source files. - **Trigger:** Running the executable or invoking an exposed tool. - **Impact:** No confirmed attack impact. - **Review source:** ai\_review - **Reviewed:** 2026-10-09T05:59:32.084Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The inspected network client limits its endpoint to loopback, and the document operation uses caller-provided paths; no malicious behavior was established. - **Rationale:** The inspected manifest has no install hook, and the reviewed network and file operations are constrained to local endpoints or caller-selected inputs. Static hints alone do not establish malicious behavior. ### Review decision - **Verdict:** Clean - **Confidence:** 91.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The manifest has no install lifecycle hook and starts the executable through src/index.mjs., The browser endpoint is restricted to loopback hosts before requests are sent., The document action code performs operations on caller-supplied PDF paths., The Linux desktop module imports local runtime helpers and operating-system APIs. ## Affected versions and remediation This report applies to @remcp/runtime@0.2.66. - Review the evidence and your use of @remcp/runtime@0.2.66 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 = 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:** 91.0% - **Path:** package.json - **Public source:** [View source]() The manifest has no install lifecycle hook and starts the executable through src/index.mjs. 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-ne ``` ### 12. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 91.0% - **Path:** src/extended/browser.mjs - **Public source:** [View source]() The Linux desktop module imports local runtime helpers and operating-system APIs. Public source snippet (untrusted): ```javascript function endpointUrl(value) { let url; try { url = new URL(optionalString(value) || process.env.REMCP_CDP_URL || DEFAULT_ENDPOINT); } catch { throw new Error('endpoint must be a valid local http(s) URL'); } if (!['http:', 'https:']. ``` ## 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:** 0.2.66 - **License:** MIT - **Version published:** 2026-09-20T21:27:14.548Z - **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:** 37 - **Artifact unpacked size:** 638,368 bytes - **Artifact signatures:** 2 - **Attestations:** Yes - **Provenance:** https://slsa.dev/provenance/v1 ## References - [HTML security report]() - [Repository]() - [Homepage]() - [Issues]()
