Local setup
The local (or stdio) version of the MCP server is available via the @sveltejs/mcp
npm package. You can either install it globally and then reference it in your configuration or run it with npx
:
npx -y @sveltejs/mcp
Here’s how to set it up in some common MCP clients:
Claude Code
To include the local MCP version in Claude Code, simply run the following command:
claude mcp add -t stdio -s [scope] svelte npx -y @sveltejs/mcp
The [scope]
must be user
, project
or local
.
Claude Desktop
In the Settings > Developer section, click on Edit Config. It will open the folder with a claude_desktop_config.json
file in it. Edit the file to include the following configuration:
{
"mcpServers": {
"svelte": {
"command": "npx",
"args": ["-y", "@sveltejs/mcp"]
}
}
}
Codex CLI
Add the following to your config.toml
(which defaults to ~/.codex/config.toml
, but refer to the configuration documentation for more advanced setups):
[mcp_servers.svelte]
command = "npx"
args = ["-y", "@sveltejs/mcp"]
Gemini CLI
To include the local MCP version in Gemini CLI, simply run the following command:
gemini mcp add -t stdio -s [scope] svelte npx -y @sveltejs/mcp
The [scope]

or local
.
