love the ability to add tools to the mcp server - would expect nothing less from emacs :)
as a long time emacs user i've only recently started really writing my own elisp tools, but claude is pretty good at writing elisp so i've been doing more there (sometimes it loses track of parentheses and you need to fix that, but overall pretty good)
I'll def be trying this out alongside steve yegge's efrit which kicks the emacs up to 11 by letting the agent just write and evaluate arbitrary elisp expressions https://github.com/steveyegge/efrit
I'm a long time Yegge fan and follower and while I think he's still in the vibe code honeymoon phase and hasn't had the vibe code hangover yet, his bona fides on emacs are up there with anyones.
It was my observation around 12-18 momths ago that LLMs are weirdly good at elisp (which kicked off all the // hypermodern stuff I'm doing.
I think he's onto something with efrit, I havent gotten it dialed yet but its reaaallyy promising.
