Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Allowed — no malicious behavior detected** — No malicious behavior detected. 10 low-signal pattern(s) reviewed. - **Verdict:** Clean - **Product-default install policy:** Allow - **Firewall policy:** No policy match - **Public report status:** Published - **Threat category:** None published - **Selected version:** 1.25.45 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. 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 code implements the package’s stated Vite observability purpose and defaults its bridge to loopback. Session replay is enabled by default but documented with controls to turn it off; no malicious collection or unrelated destination was identified. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 90.0% - **Started:** 2026-10-31T19:00:23.726Z - **Finished:** 2026-10-31T19:01:25.314Z - **Download time:** 514 ms - **Static scan time:** 57 ms - **AI review time:** 61016 ms - **Total time:** 61588 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 browser observability and replay. - **Trigger:** When a user adds the plugin to a Vite app and starts the development server; replay follows its documented settings. - **Impact:** Application events and replay data are made available to the configured LensMCP runtime; this matches the package’s stated purpose. - **Review source:** ai\_review - **Reviewed:** 2026-10-31T19:01:25.314Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Injects browser instrumentation and sends events and replay data to the LensMCP bridge, which defaults to loopback. - **Rationale:** The inspected code implements the package’s stated Vite observability purpose and defaults its bridge to loopback. Session replay is enabled by default but documented with controls to turn it off; no malicious collection or unrelated destination was identified. - **Network endpoints:** 127.0.0.1 (default bridge host; port and host are configurable) ### Review decision - **Verdict:** Clean - **Confidence:** 90.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** Package metadata points to index.js, which exports the Vite plugin and bridge event mapper., The README describes browser observability events sent to LensMCP as the package’s purpose., The API documents session replay, its default behavior, and controls to disable or configure it., The plugin defaults its bridge host to 127.0.0.1; the host is configurable. - **Evidence against:** When enabled, the plugin captures browser events and session replay, which can include application content., Replay defaults on unless disabled through the documented option, environment variable, or capture settings. ## Affected versions and remediation This report applies to @lensmcp/vite-plugin@1.25.45. - Review the evidence and your use of @lensmcp/vite-plugin@1.25.45 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.

Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 90.0% - **Path:** README.md - **Public source:** [View source]() The README describes browser observability events sent to LensMCP as the package’s purpose. Public source snippet (untrusted): ```markdown > The single Vite plugin that makes a frontend app observable by [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 instru ``` ### 9. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 90.0% - **Path:** lib/types.d.ts - **Public source:** [View source]() The API documents session replay, its default behavior, and controls to disable or configure it.
