📣 I've created a new #quarkiverse extension - quarkus-flags, a lightweight and extensible feature flags/toggles/switches #quarkus extension: github.com/quarkiverse/... Feedback, feature requests and contributions are welcome🙏.

If you want to test the business logic of your components in isolation, with different configurations and inputs, then QuarkusComponentTest is a good choice. It’s fast, integrated with continuous testing, and extensible. Learn more with this blog post by Martin Kouba quarkus.io/blog/quarkus...

📣 New #quarkus blog post - a component testing update... about class loading refactoring, QuarkusComponentTestCallbacks, integration with quarkus-panache-mock, and InjectMock support for built-in Event: quarkus.io/blog/quarkus...

Ok, I know it's boring 🥱, but we have another #quarkus MCP server minor version release - 1.7.0 with WebSocket transport, new API to customize input schema generation for Tools, and more: github.com/quarkiverse/...

🍂 A new #quarkus MCP server has fallen from the tree (metaphorically speaking) - 1.6.0 with Hibernate Validator integration, McpException moved to the public API, fixes around basic auth in McpAssured, and more: github.com/quarkiverse/...

Summer is almost over, but before fall🍃comes, version 1.5.0 of #quarkus MCP server arrives: with 2025-06-18 spec features including structured tool output, resource links and elicitation, but also RawMessage API and bugfixes: github.com/quarkiverse/...

☀️ A new summer release of #quarkus MCP server is out - 1.4.0 with "McpAssured" testing API, cancellations of of in-progress requests, subsidiary SSE streams for streamable transport, and more: github.com/quarkiverse/...

📢 And it's here... #quarkus MCP server 1.3.0 with InitialCheck API, multiple server configurations in one application, Tool annotations and improved JSON schema generation, timeouts for connection, roots and sampling, and more! github.com/quarkiverse/...

💡 03 for #quarkus extension devs: if you build a native image and wonder what's registered by Quarkus for reflection, take a look at: target/quarkus-app/quarkus/generated-bytecode.jar!META-INF/native-image/reflect-config.json 👀. That's all, thanks for your attention.

01 for Quarkus devs: with io.quarkus.runtime.ImageMode#current() you can detect the current execution mode. You get JVM if app is running in a standard JVM. NATIVE_BUILD if a native image is being built. And NATIVE_RUN if a native image is running. That's all, thanks for your attention.

We've just released #quarkus MCP server 1.2.0 with initial support for "streamable HTTP" transport, default values for ToolArg/PrompArg annotations, feature filters, and other bugfixes and minor improvements... ☕ github.com/quarkiverse/...

#quarkus MCP server 1.1.0 is out! With progress, roots and sampling APIs... ⚡https://github.com/quarkiverse/quarkus-mcp-server/releases/tag/1.1.0

Sooo, we've just released the @quarkus.io MCP server 1.0.0 🎉. The main branch is now 1.1 and we already have a couple of new features for this milestone: client sampling, Dev UI improvements and CLI adapter github.com/quarkiverse/.... We also started to look into the new spec version. Stay tuned!

The @quarkus.io team is amazing. They've developed an MCP Server extension. It took me half a day to write a not-so-trivial MCP Server and expose it to a @langchain4j.dev client. Really good stuff #Bravo github.com/quarkiverse/...

We've added an initial Dev UI support to #quarkus MCP server 1.0.0.Beta5 - there's no need to start a separate MCP client to test your features!

Believe it or not, the next release of Quarkus will be the 365th release since Quarkus became a thing, 6 years ago. It will be one year of release days! I released the large majority of them but this will change a bit with @janmartiska.bsky.social taking the responsibility for some LTS streams!

#quarkus MCP server 1.0.0.Beta3 is out! With pagination support, stdio-sse-proxy dev tool and resource subscriptions... github.com/quarkiverse/...

How I built an AI company to save my open source project On this day, 3 years ago, my world fell apart. It was a Thursday. I just finished my second meeting that morning, looked at my inbox and realized it was over. My life’s work was over. Read more: timefold.ai/blog/how-i-b...

For Quarkus, we often ask for simple reproducers when users report an issue. It might seem like wasted time for you but it's not. It happens often that the information is not enough to reproduce the issue and trying to guess how we can trigger the error is a massive waste of time on our time. 🧵

After a few more alphas, we decided to release #quarkus MCP server 1.0.0.Beta1 yesterday, yay! github.com/quarkiverse/...

Another week passed, another #quarkus MCP server Alpha release is out! 🚀 What's inside 1.0.0.Alpha3: resource templates, prompt complete, client logging, traffic logging for stdio, bugfixes... Take a look, give it a try, contribute!

Sure, every SSG can generate a sitemap.xml… but have you tried doing it with Roq? 😉 It’s clean, simple, and just feels right. Give it a shot and see why Roq might be your next favorite! 🗺️ pages.quarkiverse.io/quarkus-roq/... @quarkus.io #SSG #DevLife

Wrote about how to use Java to write a Model Context Provider and use it from Claude Desktop, LangChain4j and other MCP compatible clients.

We have just released quarkus-mcp-server 1.0.0.Alpha1, a #quarkiverse extension to build MCP servers for your #AI apps. With declarative API and #quarkus joy! github.com/quarkiverse/...

Yay! My latest blog post about Quarkus and Raspberry Pi is out: quarkus.io/blog/quarkus...
