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 observed telemetry collection is the documented, consumer-invoked purpose of this Vite observability plugin and is sent through a localhost bridge by default. Source inspection found no lifecycle execution or concrete malicious chain. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 94.0% - **Started:** 2026-08-13T05:41:37.685Z - **Finished:** 2026-08-13T05:42:14.345Z - **Download time:** 776 ms - **Static scan time:** 29 ms - **AI review time:** 35855 ms - **Total time:** 36660 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:** An opted-in Vite development plugin injects browser observability hooks and sends telemetry to its local bridge. No unconsented install-time behavior or external exfiltration endpoint is established. - **Trigger:** Consumer adds lensmcpVitePlugin() to a Vite configuration and runs Vite. - **Impact:** Captures application runtime telemetry in the opted-in development environment. - **Evidence paths:** package.json, index.js, lib/plugin.js, lib/event-mappers.js, lib/types.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-08-13T05:42:14.345Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Local WebSocket browser telemetry bridge and source instrumentation. - **Rationale:** The observed telemetry collection is the documented, consumer-invoked purpose of this Vite observability plugin and is sent through a localhost bridge by default. Source inspection found no lifecycle execution or concrete malicious chain. - **Files touched:** package.json, index.js, lib/plugin.js, lib/event-mappers.js, lib/types.js, README.md - **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:** Runtime injects instrumentation that forwards browser telemetry over a WebSocket., The plugin wraps console, fetch, route, and error handlers when explicitly enabled in Vite. - **Evidence against:** package.json has no preinstall, install, or postinstall scripts., The bridge server defaults to 127.0.0.1 and uses an ephemeral/configured local port., No child-process, filesystem-write, credential harvesting, remote URL, eval, or binary-loading code was found in package files., Activation requires a consumer to add the Vite plugin; import only exports its API. ## Affected versions and remediation This report applies to @lensmcp/vite-plugin@1.18.12. - Review the evidence and your use of @lensmcp/vite-plugin@1.18.12 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: Network - **Category:** Source - **Confidence:** 75.0% Package source references network APIs. ### 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 N=Object.defineProperty;var l=(e,t)=>N(e,"name",{value:t,configurable:!0});var x=Object.defineProperty,d=l((e,t)=>x(e,"name",{value:t,configurable:!0}),"l");import... 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: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 94.0% - **Path:** lib/plugin.js - **Public source:** [View source]() Runtime injects instrumentation that forwards browser telemetry over a WebSocket. Public source snippet (untrusted): ```javascript function open() { 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.send(JSON.stringify(chunk.length === 1 ? chunk[0] : { kind: 'batch', at: Date.now(), tabId: TAB_ID, events: chunk })); } catch (e) {} } send({ kind: 'ready', userAgent: navigator.userAgent, url: location.href }); }); ws.addEventListener('close', () => { if (openOnce) setTimeout(open, 1000); }); ws.addEventListener(' ``` ## Dependencies and install lifecycle - **Lifecycle scripts present:** No - **Dependencies:** 7 - **Optional dependencies:** 0 - **Peer dependencies:** 1 - **Development dependencies:** 0 - **Published dependency-graph edges:** 8 ### Published dependency entries - @babel/core ^7.0.0 (Dependency) - @lensmcp/bridge 1.18.12 (Dependency) - @lensmcp/core 1.18.12 (Dependency) - @lensmcp/protocol-types 1.18.12 (Dependency) - @lensmcp/react-instrumentation 1.18.12 (Dependency) - @lensmcp/valtio-instrumentation 1.18.12 (Dependency) - tslib ^2.3.0 (Dependency) - vite ^5.0.0 || ^6.0.0 || ^7.0.0 || ^8.0.0 (PeerDependency) ## Package metadata - **Package:** @lensmcp/vite-plugin - **Ecosystem:** npm - **Version:** 1.18.12 - **License:** Apache-2.0 - **Version published:** 2026-08-11T18:32:17.652Z - **Package first seen:** 2026-07-05T12:34:10.721Z - **Package last seen:** 2026-11-04T23:22:53.085Z - **Known versions:** 88 - **Latest version:** 1.25.60 - **Appeal under review:** No - **Description:** LensMCP Vite plugin — valtio alias, source transform, and browser event bridge. - **Maintainers:** davidmantoon - **Keywords:** lensmcp, mcp, observability, ai-agents, claude, vite, vite-plugin - **Runtime engines:** node: \>=18 - **Artifact files:** 11 - **Artifact unpacked size:** 40,386 bytes - **Artifact signatures:** 1 - **Attestations:** No ## References - [HTML security report]() - [Repository]() - [Homepage]() - [Issues]()
