Storybook MCP Server
Officialby Storybook
Storybook MCP Server is the official Model Context Protocol integration from the Storybook team that gives AI coding agents direct access to your UI component library. It serves component metadata, usage snippets, prop types, and documentation in a token-optimized payload, so agents generate frontend code that follows your team's design system instead of relying on generic training data. The server runs within your Storybook dev server as an addon, exposing an MCP endpoint at your Storybook URL's /mcp path. AI agents connect to browse your component catalog, read prop definitions, view usage examples from stories, and run interaction and accessibility tests. A self-healing error loop lets agents autonomously detect test failures and fix their own bugs before human review. Benchmarks from the Storybook team show that agents working with MCP context finish tasks faster using fewer tokens while producing code that stays within your standards. The addon supports React, Angular, Svelte, Vue, and Web Components. Deploy locally or host via Chromatic for remote access. Currently 271k estimated weekly visitors on PulseMCP, making it one of the most popular MCP servers available.
