Storybook MCP. Inspect components and read design docs in your terminal.

The Storybook MCP Server plugs your AI client straight into your component library. It lets you inspect every piece of UI code—the props, the structure, the docs—right from your terminal. You never gotta switch tabs or dig through local files to figure out how a component works; it's all right where you are.

Mapping Your Design System Structure

Need to know what components exist? First, run list_categories. This tool immediately spits out the top-level folder structure of your whole design system—you'll see things like 'Atoms,' 'Molecules,' or 'Templates.' You use list_components right after that; it provides a comprehensive list of every single component available inside those folders. If you want to find something specific, skip the browsing and run search_components.

This searches the whole library by keyword or component name so you can pinpoint what you need fast.

Deep Component Inspection

Once you've found a potential piece, you gotta know exactly how it works. Run get_story_args to pull up all the component’s metadata and default arguments. This tells you everything: which props it takes (e.g., label: string, isDisabled: boolean), what type they are, and if there's a default value set. It prevents you from guessing what parameters your code needs.

To figure out the implementation details, use extract_docs_guidance. This retrieves both the documented guidance for implementing the component and the local source code paths where that logic lives. That’s key—it gives you the exact file path you're looking for in your IDE.

Live Testing and Validation

Don't just read about it; test it. Use get_preview_url to generate an isolated, temporary sandbox iframe endpoint. This lets you run and check component variations live right in the terminal before you commit anything to your main build. It’s perfect for seeing how a change behaves without breaking local stuff.

You'll find that combining these tools gives you total visibility: map the structure with list_categories then narrow it down using search_components, check the required inputs with get_story_args, confirm where to put the code path via extract_docs_guidance, and finally, validate every change live using get_preview_url. It's everything you need in one place.
