#What is shadcn/ui MCP Server?

shadcn/ui MCP Server is an innovative open-source tool that equips large language models (LLMs) with rich context about shadcn/ui v4 components, enabling smarter AI-driven UI development. By implementing the Model Context Protocol (MCP), it exposes component structures, installation guides, usage examples, and metadata—streamlining tasks like code generation, debugging, or prototyping in tools like Claude Code, VS Code, Cursor, or Continue.dev. Tailored for developers working across frameworks, it pulls live data from GitHub, making it invaluable for teams accelerating shadcn-based projects. Whether you're querying for a React button variant or a Svelte dashboard block, this server acts as an intelligent bridge, reducing hallucinations and boosting productivity in AI-assisted coding workflows.

#Features ⚡️

• Multi-Framework Context: Seamless support for React, Svelte 5, Vue, and React Native—switch via flags.

• Comprehensive Component Access: Full TypeScript source, demos, dependencies, and descriptions from shadcn/ui v4.

• Blocks & Advanced Assets: Includes dashboard, calendar, and form implementations for real-world patterns.

• Smart Caching & GitHub Integration: Efficient API handling with rate-limit awareness for reliable queries.

• SSE Transport: Server-Sent Events for multi-client setups and production scalability.

• Docker Deployment: Containerized with Compose for easy hosting and self-hosting.

#Pros ✅

• AI Workflow Booster: Empowers LLMs with accurate shadcn context, cutting debugging time dramatically.

• Framework Versatility: Covers major ecosystems, ideal for polyglot teams or experiments.

• Zero-Config Start: npx simplicity with optional token for enhanced performance.

• Production Scalable: Docker and SSE make it deploy-ready for shared tools.

• Community Synergy: Builds on shadcn's open ecosystem, encouraging contributions.

#Cons ⚠️

• GitHub API Limits: Free tier caps at 60 requests/hour—token needed for heavy use.

• MCP-Specific: Requires MCP-compatible clients (e.g., Claude); not standalone.

• Early MCP Adoption: Niche protocol may limit broad tool integration.

• No Built-in UI: Server-focused—relies on client apps for interaction.

• Dependency on shadcn v4: Tied to latest version; older projects may need tweaks.

#Included Components - Templates

The server exposes shadcn/ui v4 assets via MCP endpoints, structured for LLM queries:

• Core Components: Buttons, Cards, Inputs, Modals, Tabs—full source, usage demos, and metadata.

• Blocks/Templates: Dashboard layouts, Calendar views, Form wizards with examples.

• Framework Variants: React (default), Svelte 5 ports, Vue adaptations, React Native implementations.

• Metadata Tools: Dependency lists, installation snippets, and directory explorers.

• Query Templates: Example MCP calls for "Generate a Svelte accordion" or "Explain React Native card props."

These serve as AI prompts—e.g., fetch a block's structure for instant code gen.

#Pricing 💸

shadcn/ui MCP Server is completely free and open-source under the MIT license. No tiers or costs—install via npx or Docker for personal/team use. GitHub token optional for higher limits; community-supported via contributions.
