🎙 Paolo Ricciuti - on TypeScript MCP, AI, and the Craft of Software Development

Description

Podcast page 👉 https://www.js-craft.io/blog/paolo-ricciuti-svelte-ambasador-tmpc-typescript-mcp-senior-software-developer/ I interviewed Paolo Ricciuti, a software developer from Italy. Paolo is a core contributor to Svelte.js and also a maintainer of the TypeScript MCP library. We touched on many things, but a really interesting topic is what the Svelte team is doing with its MCP server to upgrade code to new versions. Instead of putting the code as training data, they are passing the rules to the LLM on how to upgrade the code. 🎙 Chapters and topics # 0:00 - Intro & welcome 0:53 - Paolo’s origin story: games, PHP, Java, photography 3:06 - Returning to web dev and discovering Svelte 6:59 - Day-to-day: working at Main Matter 10:05 - What is MCP (Model-Context Protocol)? 14:00 - Why Paolo built TMCP (TypeScript MCP library) 15:03 - Problems with the official SDK & design decisions 22:08 - Building TMCP from a minimal JSON-RPC server 25:41 - TMCP design goals: composability, minimal deps, consistent API 31:40 - Using AI to speed up the last 30% (tests, docs, reviews) 39:16 - Why MCP brings back control to developers 40:01 - The Svelte MCP server & the “autofixer” technique 45:00 - Practical results: improving generated Svelte code 52:02 - What makes a great software engineer (curiosity) 56:00 - How Paolo learns and builds things 57:27 - Where to follow Paulo (BlueSky / GitHub) and closing Enjoy the conversation!
