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 source behavior matches the package's documented purpose: instrumenting a Vite development app and streaming its observations to LensMCP through a local bridge. Replay is enabled by default but is part of the documented observability configuration and can be disabled; no unrelated endpoint or harmful action was found. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 88.0% - **Started:** 2026-10-29T22:03:17.598Z - **Finished:** 2026-10-29T22:03:51.890Z - **Download time:** 260 ms - **Static scan time:** 56 ms - **AI review time:** 33975 ms - **Total time:** 34292 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 identified; the package provides Vite development observability and sends captured data to its local bridge. - **Trigger:** Importing and configuring the plugin in Vite; its bridge starts when Vite serves the app. - **Impact:** Captured frontend diagnostics and replay data are available to the local LensMCP bridge; no unrelated collector or harmful behavior was identified. - **Review source:** ai\_review - **Reviewed:** 2026-10-29T22:03:51.890Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Injects an observability client and optionally session replay, with a local WebSocket/HTTP bridge. The README documents event streaming as the package's purpose, and replay has configuration controls. - **Rationale:** The source behavior matches the package's documented purpose: instrumenting a Vite development app and streaming its observations to LensMCP through a local bridge. Replay is enabled by default but is part of the documented observability configuration and can be disabled; no unrelated endpoint or harmful action was found. - **Network endpoints:** 127.0.0.1 (default bridge host; port is selected or configured) ### Review decision - **Verdict:** Clean - **Confidence:** 88.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The README describes the package as a Vite observability plugin that streams frontend events to LensMCP, matching its stated purpose., The plugin attaches to Vite's serve command by default and starts its bridge on the configured host, defaulting to 127.0.0.1., Replay can be disabled with LENSMCP\_REPLAY=0/off/false or the replay option; replay data is addressed to the local bridge. - **Evidence against:** The README says the plugin's capabilities are on by default, and the replay setting defaults to enabled when no setting or capture-file opt-out is present., The plugin instruments frontend events and can record session replay, which may include application page content and user interactions. ## Affected versions and remediation This report applies to @lensmcp/vite-plugin@1.25.38. - Review the evidence and your use of @lensmcp/vite-plugin@1.25.38 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 z=Object.defineProperty;var g=(e,n)=>z(e,"name",{value:n,configurable:!0});var Z=Object.defineProperty,d=g((e,n)=>Z(e,"name",{value:n,configurable:!0}),"c");import...

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:** 88.0% - **Path:** README.md - **Public source:** [View source]() The README describes the package as a Vite observability plugin that streams frontend events to LensMCP, matching its stated purpose. Public source snippet (untrusted): ```markdown LensMCP](https://github.com/kiwiapps-ltd/lensmcp). LensMCP is an observability lens for coding agents. `@lensmcp/vite-plugin` is how a Vite-based frontend opts into that lens: add it to your `vite.config.ts` and your app starts streaming React renders, Valtio state changes, console output, network calls, route changes, runtime errors, and build events back to LensMCP — with no other source changes. Under the hood the plugin does three things: it aliases `valtio` to the instrumented drop-in [`@lensmcp/valtio-instrumentation`](https://www.npmjs.com/package/@lensmcp/valtio ``` ### 6.
