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 monitoring behavior is the package's stated Vite-plugin function and uses a localhost default after explicit project configuration. Inspection found no install-time execution or concrete exfiltration, persistence, payload staging, or destructive chain. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 94.0% - **Started:** 2026-08-14T02:18:06.853Z - **Finished:** 2026-08-14T02:18:44.389Z - **Download time:** 511 ms - **Static scan time:** 29 ms - **AI review time:** 36995 ms - **Total time:** 37536 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:** A configured Vite development plugin injects an observability client and sends captured browser diagnostics to its local bridge. No malicious attack surface was established. - **Trigger:** Developer adds and runs lensmcpVitePlugin in a Vite server. - **Impact:** Can expose development observability events to the locally configured LensMCP bridge. - **Evidence paths:** package.json, index.js, lib/plugin.js, lib/event-mappers.js, lib/types.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-08-14T02:18:44.389Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Local WebSocket browser-event instrumentation. - **Rationale:** The observed monitoring behavior is the package's stated Vite-plugin function and uses a localhost default after explicit project configuration. Inspection found no install-time execution or concrete exfiltration, persistence, payload staging, or destructive chain. - **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:** Injects a browser runtime that opens a WebSocket observability bridge., Runtime captures console, fetch, errors, and route events. - **Evidence against:** package.json has no lifecycle scripts., The bridge defaults to localhost and is activated through Vite plugin configuration., No shell execution, filesystem harvesting, credential access, remote payload loading, or destructive action was found. ## Affected versions and remediation This report applies to @lensmcp/vite-plugin@1.19.0. - Review the evidence and your use of @lensmcp/vite-plugin@1.19.0 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: 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 F=Object.defineProperty;var l=(e,t)=>F(e,"name",{value:t,configurable:!0});var N=Object.defineProperty,d=l((e,t)=>N(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]() Injects a browser runtime that opens a WebSocket observability bridge. Public source snippet (untrusted): ```javascript const o=e.enabled??!0,p=e.wsHost??"127.0.0.1",s=e.injectClient??!0; ``` ### 6. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 94.0% - **Path:** lib/plugin.js - **Public source:** [View source]() Runtime captures console, fetch, errors, and route events. Public source snippet (untrusted): ```javascript try { ws = new WebSocket(WS_URL); } catch (e) { setTimeout(open, 1000); return; } ``` ## 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 1.19.0 (Dependency) - @lensmcp/core 1.19.0 (Dependency) - @lensmcp/protocol-types 1.19.0 (Dependency) - @lensmcp/react-instrumentation 1.19.0 (Dependency) - @lensmcp/valtio-instrumentation 1.19.0 (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:** 1.19.0 - **License:** Apache-2.0 - **Version published:** 2026-08-14T01:49:36.343Z - **Package first seen:** 2026-07-05T12:34:10.721Z - **Package last seen:** 2026-11-04T20:00:29.329Z - **Known versions:** 87 - **Latest version:** 1.25.58 - **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:** 41,057 bytes - **Artifact signatures:** 1 - **Attestations:** No ## References - [HTML security report]() - [Repository]() - [Homepage]() - [Issues]()
