The plugin injects browser instrumentation and reports observed development events to its bridge. - **Trigger:** A user enables the plugin in a Vite development server; browser instrumentation is enabled by default. - **Impact:** This exposes development telemetry to the configured bridge endpoint, consistent with the plugin’s event-bridge purpose; inspected source did not establish credential theft or another attack. - **Review source:** ai\_review - **Reviewed:** 2026-10-09T10:44:34.302Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The injected client connects to the configured WebSocket host and port and sends events including fetch URLs and results. The default host is loopback. - **Rationale:** The flagged runtime bridge is first-party package functionality: the source defaults to a loopback host and sends browser telemetry to the configured bridge. The inspected behavior is package-aligned and does not establish malicious activity. - **Files touched:** package.json, index.js, lib/plugin.js - **Network endpoints:** ws://127.0.0.1:\ ### 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 entrypoint exposes the Vite plugin, and the manifest identifies matching LensMCP bridge and instrumentation dependencies., The plugin defaults its WebSocket host to loopback and injects a browser client that connects to the configured host and port., The injected client reports fetch URLs and results to the bridge; this is consistent with the plugin’s stated browser event bridge function. - **Evidence against:** No install lifecycle scripts are declared in the manifest., Inspected source shows no credential collection or outbound credential forwarding; observed browser events go to the configured bridge endpoint. ## Affected versions and remediation This report applies to @lensmcp/vite-plugin@1.22.4. - Review the evidence and your use of @lensmcp/vite-plugin@1.22.4 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.
