Storybook MCP

Build UI from your documented components, preview stories and run their tests

Storybook's official MCP comes as an addon, @storybook/addon-mcp, that serves an MCP endpoint from your running Storybook. It gives your agent your component library's documentation: which components exist, their props and their example stories.
With it, the agent builds with the components you have instead of inventing a new button. It can also find the stories a change affected, preview them and run their interaction and accessibility tests. Pair it with Playwright to check the finished page in a real browser.

Watch out

  • Storybook must be running for the server to answer.
  • The docs tools need a components manifest. They support React frameworks plus the Vite builds of Angular and Vue; Webpack Angular and Nuxt don't get them.
  • The test tool needs Storybook Test set up.

Install

Terminal

Loading editor...

npx storybook add @storybook/addon-mcp
claude mcp add --transport http storybook http://localhost:6006/mcp
Enable features: { componentsManifest: true } in .storybook/main.ts for the docs tools, then start Storybook. For other clients, run npx mcp-add --type http --url "http://localhost:6006/mcp" --scope project. Add a line to CLAUDE.md or AGENTS.md telling the agent to check Storybook first.
