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:** 0.2.173 - **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 suspicious scanner signals resolve to ordinary local runtime capabilities and MCP dependencies. The package has no install hook, and inspected telemetry is limited to filtered metrics sent through the paired agent. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 94.0% - **Started:** 2026-10-22T08:14:35.930Z - **Finished:** 2026-10-22T08:16:38.363Z - **Download time:** 1288 ms - **Static scan time:** 1483 ms - **AI review time:** 119661 ms - **Total time:** 122433 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 surface was identified. The package provides a local MCP runtime with filesystem and system tools, and its telemetry is relayed through the paired agent. - **Trigger:** The runtime starts when its command is invoked; individual tools run when requested through MCP. - **Impact:** No confirmed malicious effect was identified in the inspected source. - **Review source:** ai\_review - **Reviewed:** 2026-10-22T08:16:38.363Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** It handles local file, screenshot, and system operations using caller-supplied tool arguments, while optional telemetry sends filtered usage metrics through the paired agent. - **Rationale:** The suspicious scanner signals resolve to ordinary local runtime capabilities and MCP dependencies. The package has no install hook, and inspected telemetry is limited to filtered metrics sent through the paired agent. - **Files touched:** src/index.mjs, src/tools/files-write-edit.mjs, src/tools/files-screenshots.mjs, src/tools/system.mjs, src/telemetry.mjs ### Review decision - **Verdict:** Clean - **Confidence:** 94.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The package entry point is a local runtime command, with no install lifecycle hook in the manifest., File editing and screenshot capture are exposed as runtime tools that act on supplied arguments; the flagged process tool protects the runtime and its host agent from termination., Telemetry filters events to tool metrics and sends them through the paired runtime protocol; it does not define a third-party endpoint., The inspected runtime dependencies expose ordinary library and MCP server entry points and have no install lifecycle scripts., Bearer authentication verifies the supplied token and rejects it when its resource differs from the expected resource. ## Affected versions and remediation This report applies to @remcp/runtime@0.2.173. - Review the evidence and your use of @remcp/runtime@0.2.173 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: Previous Version Dangerous Delta - **Category:** Supply Chain - **Confidence:** 93.0% - **Path:** src/tools/system.mjs - **Public source:** [View source]() This package version adds a dangerous source file absent from the previous stored version; route for source-aware review.
