Chimp just got a significant upgrade! You can now build both typesafe MCP servers & clients, with just a couple of lines of code. Using any approach to writing Scala, in the spirit of Tapir & sttp.

+ a new documentation site, to get up to speed quickly

A bunch of updates for sttp-client 4:
• Scala Native support for the http4s backend
• cookie propagation across redirects using a CookieStorage
• three bug fixes, both found & fixed by AI

Enjoy :)

Our #Scala Skill is now compatible both with Claude & Codex - with dedicated installation instructions and necessary metadata.

🚀 Scala Days 2026 Call for Papers is now OPEN!

If you’ve been thinking about sharing your experience with Scala, functional programming, tooling, libraries, distributed systems, or anything from the Scala ecosystem — this is your chance 🎤

Whether it’s a deep technical talk, a case study, or lessons learned from real-world projects, we’d definitely encourage you to submit a proposal.

Through a series of experiments, we've prepared a direct-style #Scala Skill for Claude Code.

We wanted to make sure that it only contains what's really necessary, and to help Claude where it stumbles. Even with a 1M window, context remains precious!

[Scala Space @ScalaSpace]

That way, we've arrived at a core set of guidelines, covering FP, tooling and coding style, plus a set of fetch-on-demand, use-case driven guides.

Try it out, generate some #Scala! if you witness AI having problems with some part of the ecosystem - just create an issue.

Hey, the Scala 2 bytecode optimizer just got ported to Scala 3!
While writing nice, high level code, let the optimizer then make it faster.
Try it out today on Scala 3.8.3-RC3 with -opt.

Anthropic says JSON tool calls aren't the best thing since sliced bread and that if your agent glues tool calls together using code, it becomes 37% more token-efficient with less inference and better accuracy. Should you just let it write Python in a docker sandbox though? 1/8

Should your agent get prompt-injected and generate code that tries to, for example, send classified data to an external server, it would be a compile error as classified data simply can't flow into network calls. 7/8
