Checked on GitHub.
Overview
An MCP server that fetches shadcn/ui v4 component source, demos, blocks and metadata from GitHub for AI assistants. It supports React (Radix or Base UI), Svelte, Vue and React Native, and runs over stdio or a stateless Streamable HTTP endpoint at /mcp. GitHub API use is limited to 60 requests/hour without a token and 5000 with one.
Who it is for: Developers using MCP-capable coding agents to build UIs with shadcn components
Strengths
- Covers React, Svelte, Vue and React Native component sources from one server
- Runs via npx, stdio, stateless HTTP on port 7423, or a Claude Desktop .mcpb file
- Caching and rate-limit handling for GitHub API calls
- Ships Dockerfile and Docker Compose with a /health endpoint
Weaknesses
- Depends on the GitHub API; 60 requests/hour without a token
- Read-only lookup of component code; README does not mention installing into a project
- Legacy SSE transport was removed; --mode sse is only a deprecated alias
- Framework and UI library are chosen at startup, one per server instance
What it needs
- no GPU
- Docker + Compose
- Needs GitHub API, Node.js >= 20
- port 7423
