shadcn-ui MCP Server: Real-Time Documentation and Component Reference for AI Applications

Overview: What is shadcn-ui MCP Server?

The shadcn-ui MCP Server is a TypeScript-based model context protocol (MCP) server designed to provide real-time, detailed documentation and usage examples for the shadcn/ui component library. This server leverages web scraping techniques to extract data from official shadcn/ui resources and GitHub repositories. By implementing the MCP protocol, it enables AI applications such as Claude Desktop, Continue, and Cursor to integrate with structured, up-to-date component information seamlessly.

🔧 Core Features & MCP Capabilities

The shadcn-ui MCP Server offers a robust set of features that support AI applications through its MCP capabilities:

1. List-Shadcn-Components: Retrieves a comprehensive list of all available shadcn/ui components.
2. Get-Component-Details: Fetches detailed information about specific shadcn/ui components, including descriptions and installation instructions.
3. Get-Component-Examples: Provides usage examples for each component, demonstrating how developers can effectively integrate them into their projects.
4. Search-Components: Enables keyword-based searches across all components to quickly find relevant documentation.

The server's implementation of the MCP protocol enables seamless integration with various AI clients, making it a valuable tool for developers looking to enhance their AI applications' capabilities in terms of component reference and real-time information access.

Protocol Flow Description

The server operates by receiving requests from the MCP client. When a request is received, it processes the data according to the defined MCP protocol and then engages in web scraping or direct database queries to extract relevant information. The extracted data is then formatted into a structured response, which is passed back through the protocol before being sent as an API response. This ensures that all AI applications can interact with the server using a standardized interface.

Data Architecture Description

The shadcn-ui MCP Server's architecture involves multiple stages of handling requests and responses:

1. Client Request: The client sends a request using the defined MCP protocol.
2. Protocol Processing: The server processes the request according to the protocol.
3. Data Extraction & Integration: Data is extracted from the official documentation site, GitHub repositories, etc.
4. Staged Data & API Endpoint: The data is stored in an intermediate stage and made available via an API endpoint.
5. Client Response: The server sends a structured response back to the client.
