Vaadin Claude Plugin

Important

This marketplace is deprecated and will eventually be retired. Please switch to the new vaadin/agent-marketplace, which serves the same skills and MCP tools for both Claude Code and Codex.

/plugin marketplace add vaadin/agent-marketplace
/plugin install vaadin-skills@vaadin-marketplace

If you previously installed from this repository, remove it and re-add the new marketplace:

/plugin marketplace remove vaadin-marketplace
/plugin marketplace add vaadin/agent-marketplace

Skills and tools for building high-quality Vaadin 25 applications with Java/Flow.

Overview

This plugin provides Claude with deep knowledge about Vaadin 25 development patterns, best practices, and common pitfalls. It covers layouts, responsive design, component composition, forms, testing, data binding, and reactive state management. The plugin also integrates with the Vaadin MCP server for real-time documentation lookups.

Skills

The skills and MCP server distributed by this marketplace live in the vaadin/agent-skills repository. See that repository for the full list of skills and their documentation.

MCP Integration

The plugin bundles the Vaadin MCP server for real-time documentation lookups. See the vaadin/agent-skills repository for details on the available MCP tools.

Target Version

• Vaadin 25 (Java/Flow development model)
• Spring Boot 4 / JUnit 6 compatible

Prerequisites

• Claude Code version 1.0.33 or later (run claude --version to check)

Installation

Install from the new vaadin/agent-marketplace (recommended):

1. Add the marketplace:

   /plugin marketplace add vaadin/agent-marketplace

2. Install the plugin:

   /plugin install vaadin-skills@vaadin-marketplace

   Or open the plugin manager with /plugin, go to the Discover tab, and select vaadin-skills to install interactively.

The legacy vaadin/claude-plugin marketplace still works for now, but is deprecated and will eventually be retired. Prefer the marketplace above.

Usage

The skills and MCP tools activate automatically based on conversation context. Ask about any Vaadin development topic and Claude will use the relevant skill along with the Vaadin MCP server for up-to-date documentation.

Examples

• "Set up Aura theme with a custom color palette"
• "Create a responsive master-detail view"
• "Add form validation with Binder"
• "Write UI unit tests for my view"
• "Wrap a third-party Web Component for use in Flow"

Updating

Update the marketplace catalog by running:

/plugin marketplace update vaadin-marketplace
