Svelte Docs MCP server

The Model Context Protocol (MCP) server for Svelte 5 provides a comprehensive reference guide to help Large Language Models (LLMs) offer accurate guidance to users working with Svelte. It includes detailed information about Svelte 5 features, migration patterns from Svelte 4, common mistakes, and best practices.

Installation

You can use the MCP Svelte Docs server by configuring it in your LLM client that supports the Model Context Protocol. No separate installation is required as it runs through npx.

Configuration

Configure your LLM client to use the MCP Svelte Docs server by adding the appropriate configuration based on your operating system.

Claude Desktop (via WSL)

  "mcpServers": {
    "mcp-svelte-docs": {

      "args": ["bash", "-c", "npx -y mcp-svelte-docs"]
    }
  }
}

    }
  }
}

      "command": "npx",
      "args": ["-y", "mcp-svelte-docs"]
    }
  }
}

macOS / Linux

    "mcp-svelte-docs": {
      "command": "npx",
      "args": ["-y", "mcp-svelte-docs"]
    }
  }
}

Usage

Once configured, the MCP Svelte Docs server will automatically provide contextual information to your LLM when you ask questions about Svelte 5. The server runs in the background and enhances your LLM's responses with accurate, up-to-date information about:

• Svelte 5 features and syntax
• Migration patterns from Svelte 4 to Svelte 5
• Common mistakes and how to avoid them
• Best practices for Svelte development

Simply ask your LLM questions about Svelte 5, and the MCP server will provide the relevant documentation context to help generate more accurate and helpful responses.

How to install this MCP server

For Claude Code

To add this MCP server to Claude Code, run this command in your terminal:

claude mcp add-json "mcp-svelte-docs" '{"command":"npx","args":["-y","mcp-svelte-docs"]}'

See the official Claude Code MCP documentation for more details.

For Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > Tools & Integrations and click "New MCP Server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "mcp-svelte-docs": {
            "command": "npx",
            "args": [
                "-y",
                "mcp-svelte-docs"
            ]
        }
    }
}

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.

For Claude Desktop

To add this MCP server to Claude Desktop:

1. Find your configuration file:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json
• Linux: ~/.config/Claude/claude_desktop_config.json

2. Add this to your configuration file:

{
    "mcpServers": {
        "mcp-svelte-docs": {
            "command": "npx",
            "args": [
                "-y",
                "mcp-svelte-docs"
            ]
        }
    }
}

3. Restart Claude Desktop for the changes to take effect
