LensMCP Vite plugin — valtio alias, source transform, and browser event bridge.
AI Security Review
scanned 3d ago · by lpm-firewall-aiThe package behavior matches its stated purpose: instrumenting a Vite app and sending captured events to a local LensMCP bridge. The flagged source structure and dependency bridge imports did not reveal an unrelated collector, credential theft, or other concrete attack.
Static reason
One or more suspicious static signals were detected.; source fingerprint signature matched known malicious package; routed for review
Trigger
When the Vite plugin is configured, it attaches by default during vite serve; build attachment requires an explicit option or environment setting.
Impact
The disclosed observability and replay features expose captured app events to the configured local LensMCP bridge; no malicious behavior was found.
Mechanism
The plugin injects a browser runtime that sends observed events to a token-protected bridge. The default bridge host is 127.0.0.1; replay uploads use the bridge endpoint.
AI rationale
The package behavior matches its stated purpose: instrumenting a Vite app and sending captured events to a local LensMCP bridge. The flagged source structure and dependency bridge imports did not reveal an unrelated collector, credential theft, or other concrete attack.
Network endpoints2
ws://${host}:${port}/?__lensmcp_token=<random> (default host 127.0.0.1)${host}:${port}/replay (replay bridge endpoint; host defaults to 127.0.0.1)
Decision evidence
public snapshotAI called this Clean at 90.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The package entrypoint only re-exports the Vite plugin and event mapper.
- The README describes the browser events the plugin collects and says they are sent to LensMCP over a local WebSocket.
- The plugin defaults its WebSocket host to 127.0.0.1 and creates a per-server token for the injected runtime.
- Session replay is documented as streaming recordings to the bridge, with a LENSMCP_REPLAY setting to disable it.
Evidence against
- The package metadata and entrypoint show no install-time hook or top-level action.
- The reviewed data flow uses the plugin's local bridge; no unrelated collector or credential theft was identified.
- The scanner flags and minified source did not reveal concrete attack behavior.
