GitHub Copilot CLI

The open source repository containing the code for the MCP server is also a GitHub Copilot CLI plugin marketplace.

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

If possible, we recommend that you 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 — this will help save context by handling Svelte-specific tasks more efficiently.

Installation

In VS Code, run the Install plugin from source command and use the repository URL:

https://github.com/sveltejs/ai-tools

You can also add the repository as a marketplace from the Copilot CLI:

copilot plugin marketplace add sveltejs/ai-tools

Then, install the Svelte plugin:

copilot plugin install svelte@ai-tools

You can also run the same commands from an interactive Copilot CLI session:

/plugin marketplace add sveltejs/ai-tools
/plugin install svelte@ai-tools
