Storybook MCP
Official Storybook MCP server for React (launched March 23 2026, GA in Storybook 10.3 on April 6 2026, package `@storybook/mcp` 0.7.0 on April 14 2026). Exposes components, props, stories, MDX docs and A11y/interaction tests to any agent (Claude Code, Cursor, v0). Three toolsets: Dev (show UI in all states via live stories), Docs (discover and reuse components), Test (A11y + interaction guardrails for autonomous correction loop).
Strengths
- Official Storybook + Chromatic, no abandonment risk, public roadmap on GitHub
- Live story previews in the agent's chat: see the component rendered during the conversation
- Test toolset runs A11y + interaction tests in streaming, auto-correction loop without context switch
- Storybook Composition supported: compose multiple Storybooks (main DS + features) into a single MCP endpoint
Limitations
- Experimental status, API endpoints may evolve before Storybook 11 (Spring 2027)
- Limited to React today (April 2026), Vue/Angular/Web Components announced but not yet GA
Best for
- Team with existing Storybook wanting to open Claude Code/Cursor without letting agents invent components
- Design system manager wanting to expose DS as service consumable by all agents (not just Claude)
