It's the cost efficiency that's a big deal. Jev is an excellent cheap "first pass" model.
I'm actually pretty happy that they did it, since 90% of what I have to integrate in enterprises is MCP-driven (it's a security and auth boundary that has become pretty much mandatory for any third-party agents wanting to reach into corporate data) and this lets me use Pi directly. Am just being cautious about the first version, because, well... it's a first version, and I like my tools stable.
(I actually played around with the idea of using QuickJS myself for codemode, but since I rely on Bun that gives me the ability to use other things... never got around to do it though.)
Even Anthropic moved to auto-approve by default and they are kings of fearmongering.
Sure you can use curl along with it - but many MCP friendly harnesses don't have access to a tool like that. Wish they had added this before moving on to stuff like MCP apps.
The idea of using jev as a cheaper faster subagent for specific use cases is interesting. Will have to experiment with that!
