Add @sveltejs/opencode to your OpenCode config (either global or local):

{
	"$schema": "https://opencode.ai/config.json",
	"plugin": ["@sveltejs/opencode"]
}

Configuration

Place your configuration at one of these locations:

• ~/.config/opencode/svelte.json (global)
• $OPENCODE_CONFIG_DIR/svelte.json (if OPENCODE_CONFIG_DIR is set, takes priority)

The default configuration:

{
	"$schema": "https://raw.githubusercontent.com/sveltejs/mcp/refs/heads/main/packages/opencode/schema.json",
	"mcp": {
		"type": "remote",
		"enabled": true
	},
	"subagent": {
		"enabled": true
	},
	"instructions": {
		"enabled": true
	}
}

@sveltejs/mcp

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
