How to add the Svelte MCP server to Claude Code

Server URL: https://mcp.svelte.dev/mcp
Sign-in: No sign-in. Paste the URL and it connects.
Our hands-on result: Partial 6 of 7 tasks passed, tested Oct 16, 2026 with MCP TypeScript SDK (reference client).

Claude Code setup

claude mcp add --transport http svelte https://mcp.svelte.dev/mcp

1. Run the command, then run claude mcp get svelte to confirm it connected.

We ran the hands-on test in a reference client, not in Claude Code. This config follows Claude Code's documented format for remote (Streamable HTTP) servers. If it fails for you, tell us and we will retest.
