marmelab.com now speaks markdown to AI agents. 🤖

We enabled Cloudflare's "Markdown for Agents" on our whole domain. Send "Accept: text/markdown", get clean markdown back. Up to 80% fewer tokens than raw HTML!

A small quality-of-life improvement for AI agents crawling our site ;)

Check out the full changelog and get started here:

Shadcn Admin Kit v1.5.0 is here! 🛠️

Big updates for your admin panels:

- New DateTimeInput & TextArrayInput
- ImageField with preview support
- New doc, including I18n configuration page
- Upgraded to react-router 7.12.0 & shadcn/ui 3.8

We wrote down the boilerplate logic we're using at Marmelab if anyone wants to skip the initial setup pain.
Here’s the full breakdown of the stack and the scaffolding logic we’re using: zurl.co/5eaRi

We spent some time streamlining our admin scaffolding. We’ve been leaning heavily into @tanstack.com  Start lately, the type safety across the full stack is just too good to ignore when building complex dashboards with shadcn/ui.

We gathered our notes into a checklist to fix this, turning agents from helpers into actual producers. 

We shared our findings here:

 How are you structuring your code for AI? 💬

Sometimes using a coding agent feels slower than just writing the code yourself. 😅

We've been tweaking our codebase to make it more "agent-friendly", adding context, refining testability.

What's the main bottleneck you've found?

#AI #DevCommunity

We set up a test environment to exploit these vulnerabilities, and the results were eye-opening. 

🛡️

From tool prompt injection to cross-tool hijacking, here is what we found and how to mitigate it: marmelab.com/blog/2026/02/16...

 What’s your take on these risks? Let's discuss! 💬

We love building with MCP servers to supercharge AI agents. But at Marmelab, we're also focused on securing them.

Letting an LLM access your sensitive data based on a 3rd-party description is... risky business. 😅

How are you vetting the MCP tools your agents use? 🤔

We wrote a deep dive on our experiments with Arazzo and why it’s a game-changer for agentic workflows: marmelab.com/blog/2026/02/02...

OpenAPI is great for listing endpoints, but it fails to describe the actual workflows AI agents need to follow...

We’ve been testing Arazzo to fill this gap and finally give LLMs a "manual" to follow.

How do you handle complex API chaining with AI?

A Free Laravel Admin With API Platform and React-Admin Replace Laravel Nova with a flexible admin built on open standards and open-source tools.

Laravel admins often mean Nova. It works well. But it’s paid.

There’s a free alternative.

#Laravel + #APIPlatform + #ReactAdmin = a powerful admin UI on top of your Eloquent models.

JSX instead of PHP, but more flexibility and UI power.
