Storybook MCP Server

The Storybook MCP Addon transforms the way developers create and validate UI components by bridging a local Storybook instance with AI assistants through the Model Context Protocol. Instead of manually writing stories, testing each component state, and updating documentation, the server injects a seamless AI‑driven workflow: whenever a component is added or modified, the agent automatically generates example stories and links them back to the running Storybook. This eliminates repetitive boilerplate, reduces human error in documentation, and keeps visual tests up‑to‑date as code evolves.

At its core, the server exposes two lightweight tools. The first tool supplies the agent with clear UI‑development instructions tailored to the current component, such as required props or design tokens. The second tool retrieves live story URLs from the Storybook instance, enabling the agent to reference or embed specific component states directly in its responses. By doing so, developers can ask the assistant to “show me how this button looks in dark mode” or “verify that the card component renders correctly with a long title,” and receive instant, accurate visual feedback without leaving their editor.

The addon is particularly valuable for teams that rely on Vite‑based Storybook setups (React, Next.js, SvelteKit) and use Claude Code or other MCP‑compatible clients. It removes the manual step of writing stories, ensuring that every component has up‑to‑date visual tests and documentation. For larger projects, this translates to faster iteration cycles, fewer regressions in the UI layer, and a single source of truth for component behavior that both developers and designers can reference.

Real‑world scenarios where this MCP server shines include rapid prototyping, component library maintenance, and cross‑team handoffs. Designers can request a preview of a new button style directly from the AI, while developers can validate accessibility and responsiveness with minimal effort. Because the server communicates over HTTP, any MCP client that supports tool capabilities can integrate effortlessly—be it GitHub Copilot, Cursor, or a custom editor extension.

In summary, the Storybook MCP Addon automates the generation and linkage of component stories, enriches AI assistants with live visual context, and streamlines UI development workflows. Its simple toolset, tight integration with popular Vite‑based Storybook configurations, and broad MCP compatibility make it a standout solution for modern front‑end teams looking to harness AI without sacrificing visual quality or documentation fidelity.
