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 inspected entrypoint and implementation show a Vite observability plugin that uses LensMCP dependencies and defaults its browser event transport to localhost. No malicious behavior was established. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 94.0% - **Started:** 2026-10-09T10:44:38.042Z - **Finished:** 2026-10-09T10:45:17.656Z - **Download time:** 760 ms - **Static scan time:** 34 ms - **AI review time:** 38819 ms - **Total time:** 39614 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 plugin instruments browser activity for its LensMCP observability function and sends events to its configured WebSocket host, which defaults to localhost. - **Trigger:** A user configures the plugin in a Vite project and runs the development server; browser instrumentation is enabled by default. - **Impact:** No confirmed attack surface was established; the observed data flow is consistent with the package's stated plugin function and its default destination is local. - **Review source:** ai\_review - **Reviewed:** 2026-10-09T10:45:17.656Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The injected client connects to the plugin's WebSocket server and sends instrumentation events and basic page details. - **Rationale:** The inspected entrypoint and implementation show a Vite observability plugin that uses LensMCP dependencies and defaults its browser event transport to localhost. No malicious behavior was established. - **Network endpoints:** 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:** package.json identifies the package entrypoint and LensMCP bridge and instrumentation dependencies, consistent with a Vite observability plugin., lib/plugin.js defaults its WebSocket host to 127.0.0.1 and enables the plugin for Vite serve mode by default., The injected browser client sends events over the WebSocket and reports the page URL and user agent; no unrelated credential or exfiltration behavior was identified. ## Affected versions and remediation This report applies to @lensmcp/vite-plugin@1.23.0. - Review the evidence and your use of @lensmcp/vite-plugin@1.23.0 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. Medium: Environment Vars - **Category:** Source - **Confidence:** 75.0% Package source references environment variables. ### 2. High: Copied Package Dependency Bridge - **Category:** Source - **Confidence:** 83.0% - **Path:** lib/plugin.js - **Public source:** [View source]() Package metadata claims a different repository identity while copied source loads a runtime dependency bridge. Public source snippet (untrusted): ```javascript package = @lensmcp/vite-plugin; repositoryIdentity = lensmcp; dependency = @babel/core L1: "use strict";var P=Object.defineProperty;var d=(e,n)=>P(e,"name",{value:n,configurable:!0});import{existsSync as H,readdirSync as x,statSync as j}from"node:fs";import{delimiter as ... L2: (() => { ``` ### 3. Low: High Entropy Strings - **Category:** Supply Chain - **Confidence:** 55.0% Package source contains high-entropy string patterns. ### 4. Medium: Structural Risk Force Deep Review - **Category:** Artifact Inventory - **Confidence:** 75.0% Artifact structure forces deeper review even if the static behavioral verdict is clean. ### 5. Low: Suspicious Dependency Evidence - **Category:** Dependency - **Confidence:** 94.0% - **Path:** package.json - **Public source:** [View source]() package.json identifies the package entrypoint and LensMCP bridge and instrumentation dependencies, consistent with a Vite observability plugin.

Low: Suspicious Dependency Evidence - **Category:** Dependency - **Confidence:** 94.0% - **Path:** package.json - **Public source:** [View source]() package.json identifies the package entrypoint and LensMCP bridge and instrumentation dependencies, consistent with a Vite observability plugin. Public source snippet (untrusted): ```json "dependencies": { "@babel/core": "^7.0.0", "@lensmcp/bridge": "1.23.0", "@lensmcp/core": "1.23.0", "@lensmcp/protocol-types": "1.23.0", "@lensmcp/react-instrumentation": "1.23.0", "@lensmcp/valtio-instrum ``` ### 7. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 94.0% - **Path:** lib/plugin.js - **Public source:** [View source]() lib/plugin.js defaults its WebSocket host to 127.0.0.1 and enables the plugin for Vite serve mode by default. Public source snippet (untrusted): ```javascript xport function lensmcpVitePlugin(e={},n={}){const r=e.enabled??!0,h=e.wsHost??"127.0.0.1",a=e.injectClient??!0;let p,u;const g=L(n),s=e.aliasValtio??!0,w=e.transformSource??!0,v=e.applyOnBuild??process.env.LENSMCP_VITE_APPLY_ON_BUILD==="1"; ``` ### 8. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 94.0% - **Path:** lib/plugin.js - **Public source:** [View source]() The injected browser client sends events over the WebSocket and reports the page URL and user agent; no unrelated credential or exfiltration behavior was identified. Public source snippet (untrusted): ```javascript try { ws = new WebSocket(WS_URL); } catch (e) { setTimeout(open, 1000); return; } ws.addEventListener('open', () => { openOnce = true; while (queue.length) { const chunk = queue.splice(0, 200); try { ws.s ``` ### 9.
