Repo for the official Svelte MCP server.

Dev setup instructions

pnpm i
cp apps/mcp-remote/.env.example apps/mcp-remote/.env
pnpm dev
  1. Set the VOYAGE_API_KEY for embeddings support

[!NOTE] Currently to prevent having a bunch of Timeout logs on vercel we shut down the SSE channel immediately. This means that we can't use server.log and we are not sending list-changed notifications. We can use elicitation and sampling since those are sent on the same stream of the POST request

Local dev tools

Installation

Source-derived launch command. Check the maintainer’s required arguments and credentials before running:

bash
npx -y @sveltejs/mcp

Set up in your AI client

Merge this template into ~/Library/Application Support/Claude/claude_desktop_config.json. Keep existing servers. Add any arguments, credentials, and permissions required by the maintainer; this template has not been install-tested.

json
{
  "mcpServers": {
    "dev-svelte-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "@sveltejs/mcp"
      ]
    }
  }
}

Restart Claude Desktop completely for changes to take effect. Confirm the server appears connected in the client’s tool list, then try a read-only example from its documentation.
