How to Set Up and Use Svelte Docs
mcp-svelte-docs is a TypeScript MCP server that provides a single authoritative tool—svelte_definition—covering 28+ Svelte 5 and SvelteKit concepts extracted directly from official TypeScript declarations. It lets AI assistants look up precise syntax, parameter types, return values, and migration guidance for every Svelte 5 rune ($state, $derived, $props, $effect and variants), snippets, async await expressions, remote functions, event handling patterns, and TypeScript interfaces. Developers use it to ensure AI coding assistants always reference the actual current Svelte 5 API rather than outdated tutorials.
Prerequisites
- Node.js 18+ installed
- npx available on your system
- An MCP-compatible client (Claude Desktop, Cursor, Windsurf, etc.)
Add the server to your MCP client config
No separate installation is required. Add mcp-svelte-docs to your client config and npx will download and run it automatically on first use.
{
"mcpServers": {
"mcp-svelte-docs": {
"command": "npx",
"args": ["-y", "mcp-svelte-docs"]
}
}
}Configure for Windows (without WSL)
On native Windows, use npx directly without the wsl.exe wrapper.
{
"mcpServers": {
"mcp-svelte-docs": {
"command": "npx",
"args": ["-y", "mcp-svelte-docs"]
}
}
}Configure for Claude Desktop on WSL
When Claude Desktop runs on Windows but Node.js is inside WSL, route through wsl.exe.
{
"mcpServers": {
"mcp-svelte-docs": {
"command": "wsl.exe",
"args": ["bash", "-c", "npx -y mcp-svelte-docs"]
}
}
}Restart your MCP client
Restart Claude Desktop or your MCP client to load the new server. The svelte_definition tool will appear in the available tools list.
Use the svelte_definition tool
Query any of the 28+ available identifiers with an optional format (syntax, quick, or full). The default format is 'full' providing ~500-1000 words of documentation with examples.

Client configuration
Standard macOS/Linux configuration for Claude Desktop using npx to run mcp-svelte-docs.
{
"mcpServers": {
"mcp-svelte-docs": {
"command": "npx",
"args": ["-y", "mcp-svelte-docs"]
}
}
}Prompts to try
Example prompts that invoke svelte_definition across runes, migration patterns, and SvelteKit features.
- "Look up the $state rune in the Svelte docs and show me the full TypeScript signature"
- "Show me the quick reference for Svelte 5 snippets"
- "What is the Svelte 4 to 5 migration pattern for reactive declarations ($:)?"
- "Explain $effect.pre vs $effect in Svelte 5 with examples"
- "Show me the syntax-only format for the $derived.by rune"Troubleshooting Svelte Docs
svelte_definition returns 'identifier not found'
The server provides fuzzy matching — it will suggest the correct identifier if you have a typo. Check the available identifiers list: core runes use the $ prefix (e.g., $state, $derived), while features use kebab-case (e.g., migration-patterns, await-expressions).
npx times out or hangs on first run
The first run downloads the mcp-svelte-docs package. Ensure you have internet access and that your npm registry is reachable. You can pre-install with npm install -g mcp-svelte-docs and point the config at the global binary instead.
Server not found when using Windsurf or Cursor on WSL
Use the wsl.exe wrapper form: set command to 'wsl.exe' and args to ['bash', '-c', 'npx -y mcp-svelte-docs']. This ensures the Node process runs inside WSL where your project dependencies live.
