Released...writing MCP servers has never been easier 😎
Writing MCP servers it's quite boilerplatey but most of the times you will return a single text content from tool or a single message from prompt.
I'm adding a bunch of utils to tmcp so you can now just
return tool.text("Tool result");
or
return prompt.message("Your prompt");
Any feedback?

Hallway track is the best track of conferences, change my mind!
🤔 What if there were a conference without talks? Just hanging out with OSS maintainers & builders, seeing what they’re working on, and learning cool stuff by actually talking to people.
🤯 What if hallway track turned into the whole event!
💡 @tannerlinsley.com is exploring it. Interested? ⬇️

Neat HTML trick I've used today: let's say you have a table, and you want to add a form to insert a new element at the end.
You could add a wrapper and style the form as if it was a row, but that's not always possible AND you can't put a form inside a `tr`
The solution?

The combination of the scrollbar taking space AND view transitions will be remembered as the most atrocious experience of the 2020s.

Super exciting library from @43081j.com ...write typescript code, add some JSDoc, compile it to a working MCP server (that uses tmcp by default 😎😎😎)
Can't wait to try!

as part of some work i'm doing with a friend's co, i've published mcptool - basically a codegen CLI to turn typescript functions into MCP servers
super early days but let me know what you think! if its of use, etc 😀

I want to accept either a configuration object or a class...given TS structural typing even when you pass an object inline TS doesn't know if that's a `Name` instance...without generics it's fine but the moment I have even a single generic on test

New strategy, when someone looking for hire tells you that they don't see Svelte experience in your resume/GitHub, just fork five random svelte projects including a port of the svelte compiler in rust and send them over saying that you were working on these projects remotely.

Just published the big tmcp refactor and opened a lot of PR to the projects using it so that they don't have to think about the breaking change.
Finally, I can tick off a TODO that I had in my list from a long time to allow MCP servers deployed on serverless to retain client info! 🧡

Pro tip: when you are doing a big refactor get some of your smart friend to review it.
This way you can blame them if something breaks.

Something I've been enjoying doing lately is:
- Do some change (either with or without AI)
- When I'm satisfied, I stage all the changes
- I tell codex to look at the staged changes and update docs/write tests
I find it a very effective workflow: with the diff panel I can clearly see and review

Just finished a pretty big refactor of tmcp...it is technically a breaking change but it should be invisible for 99.9% of users, especially if they update both tmcp and the transport.
But this will allow for storing all the MCP info (client info, capabilities log level) persistently 😍

Quick PSA: the last version of sveltekit also fixes a bug with same page view transitions...BUT you need to also install the last version of svelte for it to work properly (because there was also a bug with settled) 🧡
this is auto-enabled in SvelteKit 2.48 which we released a few minutes ago. just need to have the latest Svelte version and opt into the `experimental.async` feature (svelte.dev/docs/svelte/...)
today we landed a @svelte.dev feature i'm pretty stoked about — we call it 'forking', and it lets you run state changes offscreen and later choose whether to commit them (e.g. user hovers on a link, preload data in case they click)
