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:** 0.2.157 - **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-time execution or self-dependency chain. Scanner flags correspond to on-demand screenshot support, paired-agent usage telemetry with configurable opt-out, and loopback-restricted browser access. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 94.0% - **Started:** 2026-10-17T17:50:13.657Z - **Finished:** 2026-10-17T17:51:59.893Z - **Download time:** 511 ms - **Static scan time:** 1362 ms - **AI review time:** 104362 ms - **Total time:** 106236 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 confirmed attack surface was identified. The flagged screenshot, telemetry, and browser networking code serve runtime features with bounded, package-aligned behavior. - **Trigger:** A caller invokes the screenshot or browser tools, or the runtime records usage events while running. - **Impact:** The inspected behavior supports local runtime features and usage metrics; no concrete malicious action was established. - **Review source:** ai\_review - **Reviewed:** 2026-10-17T17:51:59.893Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Screenshot capture uses a local desktop portal or OS utility; telemetry travels through the paired-agent MCP connection, and browser CDP endpoints must be loopback-only. - **Rationale:** Source inspection found no install-time execution or self-dependency chain. Scanner flags correspond to on-demand screenshot support, paired-agent usage telemetry with configurable opt-out, and loopback-restricted browser access. ### 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 defines start, check, and test scripts, with no install lifecycle script; its runtime dependencies do not include the package itself., The screenshot helper is invoked as a runtime tool and captures through the desktop portal or local OS utilities., Telemetry is sent as an MCP notification to the paired ReMCP agent; event details are filtered to a fixed set of fields., Telemetry can be disabled through runtime configuration or an environment variable., The browser CDP endpoint is restricted to loopback hosts. ## Affected versions and remediation This report applies to @remcp/runtime@0.2.157. - Review the evidence and your use of @remcp/runtime@0.2.157 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.
