Quarkus and MCP Server with HTTP SSE transport development standards and instructions

# Quarkus MCP Server

Build MCP servers with Java 21, Quarkus, and HTTP SSE transport.

## Stack

- Java 21 with Quarkus Framework
- MCP Server Extension: `mcp-server-sse`
- CDI for dependency injection
- MCP Endpoint: `http://localhost:8080/mcp/sse`

## Quick Start

```bash
quarkus create app --no-code -x rest-client-jackson,qute,mcp-server-sse your-domain-mcp-server
```

## Structure

- Use standard Java naming conventions (PascalCase classes, camelCase methods)
- Organize in packages: `model`, `repository`, `service`, `mcp`
- Use Record types for immutable data models
- State management for immutable data must be managed by repository layer
- Add Javadoc for public methods
