Markus EiseleQuarkus now speaks MCP! In this hands-on guide, I show how to turn your Quarkus Dev UI into a Model Context Protocol server. Test it locally, wire it into <a href="https://mastodon.online/tags/CursorAI" class="mention hashtag" rel="nofollow noopener" target="_blank">#CursorAI</a>, and imagine the AI-driven workflows ahead.👉 <a href="https://www.the-main-thread.com/p/quarkus-dev-ui-mcp-server-java-tutorial" rel="nofollow noopener" translate="no" target="_blank">https://www.the-main-thread.com/p/quarkus-dev-ui-mcp-server-java-tutorial</a><a href="https://mastodon.online/tags/Java" class="mention hashtag" rel="nofollow noopener" target="_blank">#Java</a> <a href="https://mastodon.online/tags/Quarkus" class="mention hashtag" rel="nofollow noopener" target="_blank">#Quarkus</a> <a href="https://mastodon.online/tags/MCP" class="mention hashtag" rel="nofollow noopener" target="_blank">#MCP</a> <a href="https://mastodon.online/tags/DevUI" class="mention hashtag" rel="nofollow noopener" target="_blank">#DevUI</a> <a href="https://mastodon.online/tags/AI" class="mention hashtag" rel="nofollow noopener" target="_blank">#AI</a>

Jukka NiiranenChatGPT added MCP support on Wednesday.ChatGPT leaked private Gmail data to attackers by Friday. 🤦‍♂️Because <a href="https://mstdn.social/tags/promptinjection" class="mention hashtag" rel="nofollow noopener" target="_blank">#promptinjection</a> is not a problem these "PhD level" AI assistants have solved.Look at that calendar invite. That text is all it took for taking over someone's <a href="https://mstdn.social/tags/ChatGPT" class="mention hashtag" rel="nofollow noopener" target="_blank">#ChatGPT</a> connected data. Allowing the attacker to use the same <a href="https://mstdn.social/tags/MCP" class="mention hashtag" rel="nofollow noopener" target="_blank">#MCP</a> enabled tools that are supposed to make AI useful at work.It really is as stupid as <a href="https://circumstances.run/@davidgerard" class="u-url mention" rel="nofollow noopener" target="_blank">@davidgerard</a> keeps telling in Pivot to AI.

Paul HoffmanHeather exposes that calling MCP an "open standard" is incorrect.It's so incorrect it could be called a lie, similar to the other lies coming from the AI world. It is not "open": it is controlled by one company with no obvious way to contribute to it. It is not a "standard": if you read <a href="https://modelcontextprotocol.io/introduction" rel="nofollow noopener" translate="no" target="_blank">https://modelcontextprotocol.io/introduction</a>, you'll see that it is described by "here, trust our code" not "here is how you can write your own code".This could have been easily fixed if they actually wanted an open standard. Setting up a quickie focused SDO with mailing lists and so on takes a few days at most. (Please don't reply that it is not possible to do it that quickly or easily: I've done it.) They didn't bother, even after announcing MCP, so it's clear they don't want an open standard.I'm glad MCP seems to work for a few use cases. <a href="https://infosec.exchange/tags/MCP" class="mention hashtag" rel="nofollow noopener" target="_blank">#MCP</a> folks: please stop lying about it an open standard or, better yet, please do the work to make it an open standard. <a href="https://mas.to/@sphcow/114697886847062461" rel="nofollow noopener" translate="no" target="_blank">https://mas.to/@sphcow/114697886847062461</a>

just small circles 🕊<a href="https://infosec.exchange/@codinghorror" class="u-url mention" rel="nofollow noopener" target="_blank">@codinghorror</a>Did coding become easier and easier, I wonder? If we look at the entirety of the software creation and delivery process, I mean. For the code editing experience I agree. Take the whole lifecycle and the complexity seems to have merely shifted to other areas than where it was before. Wading through all the countless technologies, languages, frameworks and tools we have today. Making decisions every step of the way.
