Svelte MCP — Claude Code MCP server: features and setup
The official Svelte MCP server gives agents access to Svelte docs and autofixing tools. Use it when you want an agent to consult the docs or work on Svelte code.
claude mcp add --transport http mcp https://mcp.svelte.dev/mcpWhat Svelte MCP does
Svelte MCP connects an agent to Svelte documentation and autofixing tools. That helps when you want an agent to look up Svelte guidance or fix issues in Svelte code. The description does not list the individual autofixing tools.
In Claude Code, add the server over HTTP with claude mcp add --transport http mcp https://mcp.svelte.dev/mcp. For local use, the @sveltejs/mcp CLI can run through npx -y @sveltejs/mcp. You can also install it with pnpm i @sveltejs/mcp and start it with pnpm svelte-mcp. The local option requires npx or pnpm to run.
What it helps with
- look up Svelte documentation through an agent
- ask an agent to autofix Svelte code
- connect Svelte MCP to Claude Code over HTTP
- run Svelte MCP locally from its CLI
Example prompts for the agent
- Look up how this Svelte feature works in the documentation.
- Check this Svelte code and apply the available autofixes.
- Tell me how to add Svelte MCP to Claude Code over HTTP.
