Quarkus MCP Server

Official Quarkus extension enabling Java developers to build MCP servers using the Quarkus framework — exposing tools, resources, and prompts via Quarkus CDI beans, integrating with Quarkus developer experience (hot reload, native compilation, GraalVM), and enabling enterprise Java teams to build production-grade MCP servers with Quarkus's cloud-native capabilities.

Best When

A Java enterprise team needs to build production-grade MCP servers — Quarkus provides hot reload, native compilation, CDI dependency injection, and cloud-native deployment for MCP server development.

Avoid When

Your team uses Python, TypeScript, or other non-JVM languages — or you prefer the lightweight MCP Java SDK without Quarkus overhead.

Use Cases

  • • Building MCP servers in Java/Kotlin using Quarkus CDI from enterprise backend agents
  • • Exposing existing Quarkus microservices as MCP tools from integration agents
  • • Creating native-compiled high-performance MCP servers from performance-critical agents
  • • Integrating Quarkus data services (JPA, Panache) as MCP resources from data agents
  • • Building enterprise MCP servers with Quarkus security and observability from ops agents
  • • Rapid MCP server development with Quarkus dev mode hot reload from developer agents

Not For

  • • Teams not using Java/JVM (use Python or TypeScript MCP SDKs)
  • • Lightweight scripting use cases (Quarkus has JVM overhead for small scripts)
  • • Non-Quarkus Java projects (use MCP Java SDK directly)

Known Gotchas

  • ⚠ Requires Quarkus project setup — not a standalone server like other MCPs
  • ⚠ JVM startup time may be noticeable unless using native compilation (GraalVM)
  • ⚠ Extension API evolves with Quarkus releases — keep extension version aligned with Quarkus BOM
  • ⚠ Dev mode hot reload works for tools/resources but some config changes require restart
  • ⚠ Quarkiverse extension — maintained by community contributors, not core Quarkus team
  • ⚠ Binary transport only via stdio — HTTP/SSE transport requires additional config
