Day 23 Svelte MCP

"I'm sorry, I can't do that." Even HAL 9000 needs a little help sometimes! When AI models try to write Svelte 5 code, they stumble over runes like reindeer on an icy rooftop. Enter the Svelte MCP — Santa's secret weapon for teaching old models new tricks!

Run npx sv add mcp and watch the CLI work its holiday magic. It creates an instructions file (like a letter to Santa, but for your AI) and wires up everything with a festive bow. Your LLM now has a direct sleigh-line to the official Svelte documentation!

The real Christmas miracle? The Svelte Autofixer! Like Santa's quality-control elves, it reviews your AI's code and whispers corrections: "Use onclick, not on:click!" The AI iterates until the code sparkles brighter than tinsel — even GPT-4.1, which has never unwrapped Svelte 5 before!

When your component is polished and ready to go under the tree, ask for a Playground link to test it instantly. From confused robot to working Advent calendar faster than you can say "Ho ho ho!" — that's the gift of the Svelte MCP!
