What it does

This plugin gives Claude access to mvnpm tools so it can:

• Search NPM packages available as Maven artifacts

• Browse artifact contents (JAR/TGZ files)
• Check Maven Central sync status
• Monitor the sync pipeline and event logs

• "What's the Maven coordinate for @hotwired/stimulus?"
• "Is htmx synced to Maven Central?"
• "Generate an import map for lit and @vaadin/router"
