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!
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 😀

@andarist.bsky.social I have this situation here
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

From a great idea from @bhidesvelte.bsky.social now the svelte extension for @raycast.com features a sv cli composer to quickly pick all the options to create/add an add-on to your project!

Just published a new package `@tmcp/test`, an InMemoryTransport to test your tmcp MCP servers with ease...there's still a bit to do but if you want to check it out and give feedback on the API it would be great!

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 😍
Take a look!

This looks very cool...if the runtime cost is not too big might be cool to use, will explore later 🤟🏻

It looks like you encountered a problem... Svelte development will resume in a while.

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)

To me it's like there's a Svelte experience before Bluesky, and a totally different one after subscribing.

Yes I installed Zed...no I don't plan to switch from VS Code why would I?
At this point, 90% of the software I install is an MCP client to test if the svelte MCP server works correctly there 😁

Switch to tmcp for yours MCPs, you won't regret it...and we have cookies 🍪
This is what happens when you migrate your MCP server from from the official @modelcontextprotocol/sdk to tmcp by @paolo.ricciuti.me. 😱
And of course it's not just that, it's also the whole API being better to use and more typesafe. It's like Webpack vs Vite.
Paolo is cooking with tmcp, no contest
