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. Inspected source ties collection and transmission to the package’s stated browser observability purpose and a configurable LensMCP bridge, with a local fallback. No install-time execution, unrelated collector, or concrete attack behavior was found. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 94.0% - **Started:** 2026-10-29T01:09:54.438Z - **Finished:** 2026-10-29T01:10:42.881Z - **Download time:** 260 ms - **Static scan time:** 169 ms - **AI review time:** 48013 ms - **Total time:** 48443 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 browser telemetry and session replay directed to the LensMCP bridge configured by the integrating application. - **Trigger:** Importing the auto subpath or calling the exported setup functions in a browser. - **Impact:** The intended effect is application observability. Replay data can contain page content when the application has not marked private content or enabled input masking. - **Review source:** ai\_review - **Reviewed:** 2026-10-29T01:10:42.881Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The runtime gathers browser events and replay data and sends them to the configured bridge; the fallback bridge is local to the browser host. - **Rationale:** Inspected source ties collection and transmission to the package’s stated browser observability purpose and a configurable LensMCP bridge, with a local fallback. No install-time execution, unrelated collector, or concrete attack behavior was found. - **Network endpoints:** 127.0.0.1:5747 ### Review decision - **Verdict:** Clean - **Confidence:** 94.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The manifest describes browser capture streamed to the LensMCP bridge and exposes an explicit auto-import subpath., The auto entry installs capture only when imported, resolving the bridge URL and token from caller options or page configuration; its fallback is a local bridge., The runtime captures browser errors, console output, fetch metadata, and route changes, consistent with the package description., Replay starts through the auto setup path and uploads recorded data to the configured endpoint; no unrelated fixed collector appears in the inspected path., The replay uploader sends payloads to that endpoint and omits browser credentials from its requests., Required dependency manifests and source excerpts show the declared LensMCP core and rrweb recorder/types packages; the core includes URL parameter redaction. - **Evidence against:** Replay privacy defaults do not mask all input values, so captured session content may include sensitive page data unless the application marks private content or configures privacy. This is a product capability, not evidence of an unrelated recipient or covert collection. ## Affected versions and remediation This report applies to @lensmcp/client-runtime@1.25.34. - Review the evidence and your use of @lensmcp/client-runtime@1.25.34 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.
