Overview

The open source repository containing the code for the MCP server is also a Claude Code Marketplace plugin.

The marketplace allow you to install the svelte plugin which will give you both the remote MCP server, a skill to instruct the LLM on how to properly write Svelte 5 code, and a specialized agent for editing Svelte files.

If possible is recommended to instruct the LLM to execute MCP calls with the agent (you can explicitly mention an agent in your message to delegate work to it) when creating or editing .svelte files or .svelte.ts / .svelte.js modules as it helps save context by handling Svelte-specific tasks more efficiently.

Installation
