mcp-svelte-docs

This MCP server exposes a single, powerful tool called svelte_definition. It provides authoritative, TypeScript-first definitions for Svelte 5 and SvelteKit concepts. You can query a wide range of runes (like $state, $derived, $props, and the full $effect family), development patterns (snippets, await-expressions, remote-functions), event handling, migration guidance, and TS interfaces (snippet, snapshot). Use the tool by passing an identifier and an optional format to the svelte_definition call. Formats include syntax (TypeScript signature only), quick (definition plus a concise example), and full (comprehensive documentation with examples). For example, svelte_definition("$state") returns complete $state documentation, while svelte_definition("onclick","syntax") returns just the TypeScript signature for the onclick concept. The service is designed to be a single interface that covers 28+ definitions, ensuring consistent responses whether you request a rune or a feature. The server also includes smart error recovery, fuzzy matching for typos, and migration help to bridge Svelte 4 patterns to Svelte 5 equivalents.

Prerequisites:\n- Node.js and npm (or a Node-enabled environment).\n- Internet access to fetch the MCP server package.\n\nInstall steps:\n1) Ensure Node.js is installed. Verify with: node -v and npm -v.\n2) You can run the MCP server directly with npx (no global install required):\n\nbash\nnpx -y mcp-svelte-docs\n\n3) Alternatively, if you prefer a local install, you can install the package locally in your project and run it from node_modules/.bin:\n\nbash\nnpm install --save-dev mcp-svelte-docs\n./node_modules/.bin/mcp-svelte-docs\n\n4) On Windows, macOS, or Linux, the same commands apply; in Windows you can also use a script or PowerShell to invoke npx.\n5) To customize the run, pass your preferred arguments, for example:\nbash\nnpx -y mcp-svelte-docs\n\n6) If you are using a GUI-based launcher or integration, configure it to use the command and arguments shown above.\n\nNotes:\n- The repository provides a ready-made configuration snippet that demonstrates using npx to run the server.\n- No global install is strictly required, thanks to npx.\n

Tips and considerations:\n- The server provides a single tool, svelte_definition, to access 28+ Svelte 5 definitions. Use the format parameter to tailor the output to your needs (syntax, quick, full).\n- If you’re integrating with editors or IDEs, you can call svelte_definition through your MCP client and display the returned documentation in-context.\n- The available identifiers cover core runes, development tools, features, patterns, event handling, and TS interfaces, enabling comprehensive coverage of Svelte 5 concepts.\n- See the Config examples in the README for different environments (Claude Desktop via WSL, Windsurf, Windows with and without WSL, macOS/Linux).\n- If you encounter typos or missing identifiers, the smart error recovery and related concept linking can help you find the correct term quickly.
