This week we're joined by Paolo Ricciuti, a Svelte maintainer and the creator of TMCP. We talk about his journey into the world of software development, his work on Svelte, and his new project TMCP. There has been a lot of changes in the Svelte ecosystem since we last talked to Rich, so we're excited to hear about the new features and improvements in Svelte 5!

A podcast interview with Paolo Ricciuti, a Svelte team maintainer at Mainmatter, covering Svelte 5's runes-based reactivity system, async/await in components, SvelteKit remote functions (RPC), and his TMCP library for building MCP servers. Paolo explains how Svelte 5 moved from compile-time reactivity to a signal-based model enabling TypeScript file usage and deep dependency tracking. He discusses the experimental async features and remote functions in SvelteKit that simplify server-client data loading with security considerations. He also covers TMCP, a lightweight alternative to the official MCP TypeScript SDK with modular transports and standard schema support, and ongoing work on custom renderers for Svelte to enable native and terminal rendering targets.
