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 attack behavior. The flagged screenshot and network features serve local runtime capabilities, while telemetry is bounded and routed through the paired agent. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 94.0% - **Started:** 2026-10-18T02:01:58.333Z - **Finished:** 2026-10-18T02:03:36.604Z - **Download time:** 510 ms - **Static scan time:** 1380 ms - **AI review time:** 96379 ms - **Total time:** 98271 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 package provides a locally invoked MCP runtime with screenshot and browser tools. - **Trigger:** The runtime starts when invoked; individual capabilities run when their MCP tools are called. - **Impact:** No harmful effect or unauthorized data transfer was established. - **Review source:** ai\_review - **Reviewed:** 2026-10-18T02:03:36.604Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Screenshot capture uses the local desktop portal or local capture utilities. Telemetry contains whitelisted runtime and tool metadata and is sent through the paired agent. - **Rationale:** Source inspection found no install hook or concrete attack behavior. The flagged screenshot and network features serve local runtime capabilities, while telemetry is bounded and routed through the paired agent. - **Files touched:** package.json, src/index.mjs, src/screenshot-portal.mjs, src/tools/files-screenshots.mjs, src/telemetry.mjs, src/config.mjs, src/extended/browser-endpoint.mjs ### 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; its scripts are start, check, and test., The screenshot portal requests a screenshot through the local desktop portal and accepts only a local file URI., The screenshot tool runs on request and returns the captured image through the runtime tool response., The entrypoint starts the MCP server when the runtime process is invoked., Telemetry whitelists tool metadata and sends it through the paired ReMCP agent; the user can disable it., The browser CDP default endpoint is loopback. ## Affected versions and remediation This report applies to @remcp/runtime@0.2.164. - Review the evidence and your use of @remcp/runtime@0.2.164 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.
