A Model Context Protocol (MCP) server providing authoritative Svelte 5 and SvelteKit definitions extracted directly from TypeScript declarations. Get precise syntax, parameters, and examples for all Svelte 5 concepts through a single, unified interface.
Definition-First Approach: Rather than multiple specialized tools,
this server provides one powerful svelte_definition
tool that
accesses 28+ comprehensive definitions covering:
svelte_definition
Single, powerful tool for all Svelte 5 and SvelteKit concepts:
svelte_definition(identifier: string, format?: "syntax"|"quick"|"full")
Examples:
svelte_definition("$state")
- Complete $state documentationsvelte_definition("snippets", "quick")
- Snippet overview with
examplesvelte_definition("onclick", "syntax")
- Just the TypeScript
signaturesvelte_definition("migration-patterns")
- Svelte 4 → 5 migration
guideResponse Formats:
"syntax"
- TypeScript signature only (~50 words)"quick"
- Definition + minimal example (~200 words)"full"
- Complete documentation with examples (~500-1000 words,
