What it does
This MCP server provides Claude with comprehensive access to React Spectrum documentation. React Spectrum encompasses multiple complementary libraries: React Spectrum (Adobe's Spectrum design system implementation in React), React Aria (unstyled React components and hooks for building accessible interfaces), React Stately (state management hooks for cross-platform use), and Internationalized (framework-agnostic internationalization utilities). The server reads documentation from the local filesystem and supports network calls to fetch updates, with write access for persistence.
Who it's for
Frontend engineers building custom component libraries with accessibility requirements, product teams adopting Adobe's Spectrum design system, and developers integrating React Aria or React Stately into existing applications. Particularly valuable for those who need real-time access to library APIs and accessibility patterns during development.
Common use cases
- Reference React Aria component implementations and WAI-ARIA patterns
- Look up React Stately hooks for state management across platforms
- Query Spectrum theming options and design tokens
- Find keyboard navigation and screen reader support patterns
- Retrieve i18n strategies from the Internationalized packages
Setup pitfalls
- Requires filesystem read and write access—carefully review permissions before deploying in sandboxed or restricted environments
- Documentation stored locally; initial setup may involve downloading and caching documentation files
- High-risk classification due to filesystem permissions—implement proper access controls, validate file paths, and restrict scope before production use
- Network calls are made to fetch documentation updates; ensure network access is configured if behind a proxy or firewall
