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/...

Let's #workTogether ! No job description yet, but, hear me out: I've recently left #RedHat, to do something I feel is more meaningful: help build a better home for #OpenSource: radicle.xyz We're now looking for someone with experience in the #frontend world and a #UX focus to join my team! 👇

Getting ready for secure MCP with Quarkus MCP Server: quarkus.io/blog/secure-...

The best way to write MCP servers just keeps on getting better!

Fastest way to get started with Java and MCP ? jbang init -t qmcp@jbangdev hello.java Now add `jbang hello.java` to your favourite MCP client. I'll show this and more on Quarkus Insights at 15:00 CET

Just published an article on deploying #Azure resources using the Model Context Protocol (#MCP) and @quarkus.io ! Learn how to build MCP servers that let you manage cloud resources using simple natural language commands right from @vscode.dev . www.linkedin.com/pulse/deploy...

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!

We released Quarkus 3.20 LTS, our new LTS stream maintained for 1 year, and Quarkus 3.21, which comes with new features such as the ability to configure the MongoDB Client with the TLS Registry. For 3.20 LTS, buff.ly/UTh9roX , for 3.21, buff.ly/xrfibVb . Pick the one that fits your needs!

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/...

Remember, there is an intrinsic feedback availability imbalance: we deal with bad stuff daily, and it is more visible than good stuff. For every ugly customer support ticket, there are likely hundreds of customers who never told you things were great.

Here's the 3rd episode of my #Java and #AI series with #Quarkus & #LangChain4j 💥 ! It talks about keeping memory of subsequent and parallel calls to AI Models. Want to find out what LLMs think is the best enterprise programming language and stack? You'll just have to watch 😁 youtu.be/at9vlItauKU?...

Its been awesome to see the work Andrea and co. been doing with WASM using Chicory. Latest is enabling sqllite to run in raw jvm bytecode and native-image. quarkus.io/blog/sqlite4... Also works with jdbc@maxandersen: gist.github.com/maxandersen/...

#LangChain4j 1.0.0-beta2 has been released! 🎉 github.com/langchain4j/...

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!

What's your favorite #Quarkus extension and why? #Java #Quarkiverse

There is a new way to run sqllite in java with Quarkus - no native libraries, simple to run with java and still native image friendly. Read about the new sqllite4j quarkiverse extension in the blog below!

Quarkus 3.19 introduces a new landing page for #observability. It provides an overview of available extensions and best practices for their use. Check it out: quarkus.io/guides/obser... @quarkus.io

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!

I love just how free the new AOT cache is! For the a sample Quarkus application, normal startup time was around 400ms on my machine (JDK 24 EA). When using the new AOT cache feature with JDK 24, the application starts in around 270ms. And all that without a training run! bsky.app/profile/dani...

@quarkus.io has now a page in the oficial @opentelemetry.io documentation. opentelemetry.io/docs/zero-co...

Nice - #Quarkus has an official page in the #OpenTelemetry docs now - opentelemetry.io/docs/zero-co... #java #observability

Did you know you can use #Quarkus (+ #LangChain4j) as both an #MCP client AND an MCP server? I created a quick sample to add current weather awareness to an LLM integration. Check it out and let me know -> github.com/quarkiverse/... #Java #AI @quarkus.io @langchain4j.dev

Great examples of agentic AI with @quarkus.io and @langchain4j.dev from Mario Fusco: github.com/mariofusco/q...

Noticed Cursor added MCP support and yes - Quarkus MCP servers Just Works. Screenshot is me talking to a netflix sqllite database...

Great turnout! Come and join @quarkus.io AI hands-on workshop at @jfokus.se @kevindubois.com @geoand86.bsky.social @ericdeandrea.dev

All Hands-on lab are fully booked this morning! #Quantum with Gavin King, Java for Cloud with @rustam.no, Testcontainers with @shelajev.bsky.social and LangChain4j with @kevindubois.com, @danieloh30.bsky.social, @geoand86.bsky.social and @ericdeandrea.dev

Read Max Rydahl Andersen's blog post to see how to implement an MCP server using Quarkus, allowing you to extend AI applications with custom tools powered by the Java ecosystem. https://buff.ly/40zcNxV

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. 🧵

well look at that: kubernetes MCP available from github.com/quarkiverse/... thanks to @marcnuri.com and github.com/wildfly-extr... a WildFly MCP server using Quarkus by jfdenise!

Attending @jfokus.se and looking for a good hands-on workshop? Join @kevindubois.com @danieloh30.bsky.social @geoand86.bsky.social and myself Monday Feb 3 from 9:00-12:30 in Room 27 to learn how to create #ai infused apps with @langchain4j.dev @quarkus.io https://buff.ly/3YgrzJP

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

Stepping up how we do LTS releases - been long time coming! Curious on feedback and the next step of automating this more and more.

You want to try out that new fancy DeepSeek LLM you heard about? Just need to set base-url and model names or use ollama. Made a gist showing how to configure remote and local options. https://buff.ly/3CCc074 Enjoy )

A very informative presentation from Guillaume: gnodet.github.io/maven4-prese... #maven #maven4

Just explored the shift from @spring.io to @quarkus.io, and I'm seriously impressed! Quarkus enhances the developer experience with features like Dev UI, Dev Services, and its extensions. Check out my journey so far 👇 https://buff.ly/3E3NoEO #TechAtWorldline

See how to use Quarkus and LangChain4j to easily create an application that connects to an MCP server providing filesystem-related tools in this blog post by Jan Martiška. https://buff.ly/4gM9N7X

Kims hard numbers on what it meant for his team to move to Quarkus is awesome to see.

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!

Can't wait to be back at @jfokus.se to dissect vulnerabilities in AI apps with master (mis)chief @brianvermeer.nl from Snyk

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

#LangChain4j 1.0.0-alpha1 is out! 🥳 There is a lot of good stuff in this release: 1. Preparing to release the stable 1.0.0 version in Q1 2025 2. New chat model API 3. Support for #MCP (Model Context Protocol) from @anthropic.com ... 🧵👇

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/...

We have defined the schedule for our next LTS: it will be Quarkus 3.20, released at the end of March. The feature freeze for this version is Feb 11th, the day before the release of Quarkus 3.19.0.CR1 (as 3.20 will be the continuation of the 3.19 branch).

With the latest Quarkus LangChain4j 0.23.0.CR1, wring agents just got a lot easier! Our weather agent example should give you a really good idea: github.com/quarkiverse/...

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

Quarkus Playpen enables development within a cluster. Temporarily route requests to a service to your laptop or to a temporary pod.  This allows you to develop realtime with a cluster so that you can see your service in action with the rest of your service mesh. See

We released Quarkus 3.17.2 with some fresh bugfixes.

We released Quarkus 3.17 which comes with improvements to observability and programmatic permission checkers. The REST Clients were updated to MicroProfile REST Client 4.0. We will push new micros in December but the next minor will be 3.18 released at the end of January.
