React Native Storybook MCP server

This MCP server enables interaction with Storybook through the Model Context Protocol, allowing you to retrieve and work with Storybook stories programmatically.

Installation

To use the Storybook MCP server, you'll need to have Bun installed on your system. Once Bun is installed, you can run the server directly from its location.

Running the Server

Start the MCP server by running:

bun [path-to]/storybook-mcp/index.ts

Replace [path-to] with the actual path to the storybook-mcp directory on your system.

Available Tools

The server provides tools to interact with your Storybook configuration.

Getting Stories

The get-stories tool allows you to retrieve a list of all stories from your Storybook configuration.

Parameters:

• configDir (string): The absolute path to the directory containing your .storybook config folder

Example usage:

// Example of how to call the get-stories tool
const response = await mcp.tools.call('get-stories', {
  configDir: '/absolute/path/to/project'
});

// Response will be an array of stories in "title/name" format
// e.g. ["Button/Primary", "Button/Secondary", "Card/Default"]

Performance Notes

The server caches data in a ./cache directory relative to the script location to improve performance for repeated requests.

How to add this MCP server to 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 > MCP and click "Add new global MCP server".

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

{
    "mcpServers": {
        "cursor-rules-mcp": {
            "command": "npx",
            "args": [
                "-y",
                "cursor-rules-mcp"
            ]
        }
    }
}

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 explictly ask the agent to use the tool by mentioning the tool name and describing what the function does.
