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:** 0.2.174 - **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. Source inspection found no install hook or concrete malicious behavior. The flagged dependency code provides DBus and MCP transport functionality, while telemetry is disclosed, scoped to usage events, and delivered through the paired agent. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 89.0% - **Started:** 2026-10-22T13:54:50.645Z - **Finished:** 2026-10-22T13:56:23.687Z - **Download time:** 1020 ms - **Static scan time:** 1470 ms - **AI review time:** 90551 ms - **Total time:** 93042 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 a local MCP runtime with filesystem and screenshot tools and disclosed usage telemetry. - **Trigger:** A user or paired ReMCP agent starts the runtime and invokes an available tool. - **Impact:** The inspected behavior supports the package’s stated local-device runtime function; no concrete attack impact was established. - **Review source:** ai\_review - **Reviewed:** 2026-10-22T13:56:23.687Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The runtime serves MCP over standard input and output; requested filesystem operations resolve paths through its runtime path policy, and screenshot capture loads the DBus client when called. - **Rationale:** Source inspection found no install hook or concrete malicious behavior. The flagged dependency code provides DBus and MCP transport functionality, while telemetry is disclosed, scoped to usage events, and delivered through the paired agent. ### Review decision - **Verdict:** Clean - **Confidence:** 89.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json defines only start, check, and test scripts; it has no install lifecycle hook., Telemetry is disclosed, can be disabled, and records sanitized usage events without file paths, commands, arguments, or tool output., Telemetry is sent through the runtime’s paired-agent MCP notification; the inspected MCP event subscription and stdio transport are ordinary protocol handling., The screenshot dependency is loaded inside the portal screenshot function, and filesystem tools expose requested read and write operations through MCP., Inspected dependency manifests contain build, lint, and test scripts; their source exports DBus and MCP protocol functionality. ## Affected versions and remediation This report applies to @remcp/runtime@0.2.174. - Review the evidence and your use of @remcp/runtime@0.2.174 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.

Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 89.0% - **Path:** src/config.mjs - **Public source:** [View source]() Telemetry is disclosed, can be disabled, and records sanitized usage events without file paths, commands, arguments, or tool output. Public source snippet (untrusted): ```javascript // (`sudo remcp install --system`) or start it under sudo. const unrestricted = booleanValue(process.env.REMCP_RUNTIME_UNRESTRICTED, booleanValue(file.unrestricted, false)); // Telemetry is opt-out, matching the ReMCP client: it is on unless the user (or the // ReMCP agent that spawned this runtime) turns it off. It never sends file paths, // command strings, arguments, or tool output - only tool names, timings and outcomes. const telemetryDisabled = bool ``` ## 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 ^2.3.0 (Dependency) ## Package metadata - **Package:** @remcp/runtime - **Ecosystem:** npm - **Version:** 0.2.174 - **License:** MIT - **Version published:** 2026-10-22T13:35:39.763Z - **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:** 88 - **Artifact unpacked size:** 983,645 bytes - **Artifact signatures:** 2 - **Attestations:** Yes - **Provenance:** https://slsa.dev/provenance/v1 ## References - [HTML security report]() - [Repository]() - [Homepage]() - [Issues]()
