Engineers, what MCPs are you actually using in development? I'm fishing for tips

My favourites so far:
▪️ Supabase - great for debugging
▪️ Playwright - creates a tight feedback loop for agents to fix bugs or style based on designs
▪️ Stripe - beats clicking around dashboards

I’ll be in San Francisco July 3-10. If you’re in town, I’d love to meet up and chat about AI agents!

Any events/meetups you’d recommend?

This iterative approach makes your code easier to understand, debug, and maintain while keeping memory usage minimal ✅

⛓️ Chained SQL queries in Deepnote

Yesterday, @DeepnoteHQ launched something that I've really enjoyed working on, ⛓️ Chained SQL.

Instead of writing massive, hard-to-test queries at once, you can now write your SQL in reusable building blocks that you can reference downstream: www.loom.com/share/d47bc...

Thank you @e2b and @tereza_tizkova for organizing the event!

Had a lot of fun over the weekend at the @e2b hackathon! 🧑‍💻

Together with @vireliam, @yggdrasill501 and @cicmen35, we've hacked a learning platform which uses AI to set up personalized course roadmaps and generates interactive exercises for each lesson.

This blog post from @yggdrasill501 explains what Modules are and how you can use them to start building your semantic layer within just a couple of clicks 📚

PS: There's more in store for Modules coming soon 😉

Big shoutout to our incredible @jankuca, Gabor Szalai, @aleschromec and everyone across the company who contributed 💙

Modules intro

Have a look at Gabor's walkthrough to learn more: www.loom.com/share/c9c40...

This isn’t just an upgrade—it’s a entirely new way of organizing and scaling your data workspace. Modules take notebooks from isolated analyses to interconnected and consistent workflows. 🔁

Make your best and most trusted work instantly accessible. With Modules you can seamlessly insert standardised metrics into your analysis, build ETL pipelines or reuse your favourite code snippets and SQL queries. 🧩

🧱 Modules are a game-changer for building complex workflows with notebooks. Define once, reuse everywhere—it’s that simple.

@DeepnoteHQ is one of my favourite places to write SQL.
The AI code completions and intellisense are super-helpful.

But it would be nice if there was a clean way for me to build and test parts of my query separately before assembling the final version... 👀

Deep research from @perplexity_ai is what perplexity should have been since the beginning

It'd be great if @windsurf_ai, @cursor_ai and @GitHubCopilot agreed on a standard file format for custom AI instructions.

Even better if tools like Devin from @cognition_labs used it too!

It's good to be back and building

🎁 Use Deepnote AI for Free

🛺 New SQL autocomplete in Deepnote

For the past few weeks, I've been working on @DeepnoteHQ's new SQL autocomplete experience.

Let me show you what's new 👇 www.loom.com/share/1c152...

Code folding in Deepnote

📂 And @OlegWock added code folding for longer Python blocks. Quality of life improvement for all the power users!

Deepnote AI: Custom instructions

🧑‍🏫 You can now tweak how you'd like Deepnote AI to respond with custom instructions.

SQL autocomplete in Deepnote

🎄 Final @DeepnoteHQ release of 2024:

🛺 I've worked on revamping our SQL autocomplete experience from the ground up making it suggest smarter completions faster.

@typefully is great btw

Bye bye bots 👋

"Use @typefully to grow your audience faster"

My audience:

🚛 And @OlegWock shipped sweet improvements to our data table. You can now rename, move or even hide columns

🏎️ We've also made performance updates leading to up to 7x faster notebook loading. Kudos go to @jakubowskiandy!
