Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "webcomponents-react": {
      "command": "npx",
      "args": [
        "-y",
        "@ui5/webcomponents-react-mcp"
      ]
    }
  }
}

Run this in your terminal

claude mcp add webcomponents-react -- npx -y @ui5/webcomponents-react-mcp

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "webcomponents-react": {
      "command": "npx",
      "args": [
        "-y",
        "@ui5/webcomponents-react-mcp"
      ]
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "webcomponents-react": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "@ui5/webcomponents-react-mcp"
      ]
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Common questions

Is Webcomponents React MCP Server safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (2.28.2) reached the registry 10 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

UI5 Web Components for React MCP Server

MCP server providing development assistance and API documentation for UI5 Web Components for React.

What is this?

This MCP server gives AI assistants direct access to UI5 Web Components for React documentation, component APIs, and utility information. It helps developers get accurate, up-to-date information about the library without leaving their IDE.

Setup

This server is available in the MCP Registry, which allows compatible clients to install it directly.

Claude Code

claude mcp add ui5-wcr -- npx @ui5/webcomponents-react-mcp@latest

VS Code / Cursor

Add to .vscode/mcp.json:

"servers": { "ui5-wcr": { "command": "npx", "args": ["@ui5/webcomponents-react-mcp@latest"] } } }

Pinning a Specific Version

The MCP server is available since @ui5/webcomponents-react@2.21.3. It shares the same version number and bundles documentation and API data for that specific release. Pinning the version to match your project ensures the AI assistant provides accurate information for the components and APIs you are actually using.

Append @ to install a specific version. Note that after updating @ui5/webcomponents-react, you need to update the pinned MCP server version accordingly.

npx @ui5/webcomponents-react-mcp@2.21.3

To match the version of @ui5/webcomponents-react installed in your project, run from the project root:

_This requires @ui5/webcomponents-react to be installed in the project's node_modules._

npx @ui5/webcomponents-react-mcp@$(node -p "require('@ui5/webcomponents-react/package.json').version")

Transport

The server supports two transports. Both run locally on the developer's machine.

stdio (default)

Used by the Setup configurations above. The client spawns the server as a subprocess and communicates over stdin/stdout. No flags are required.

HTTP (Streamable HTTP)

Some MCP clients connect over HTTP instead. Start the server with the --http flag to enable the Streamable HTTP transport:

npx @ui5/webcomponents-react-mcp@latest --http

The server listens on http://localhost:7427/mcp. Change the port with --port (or the PORT environment variable):

npx @ui5/webcomponents-react-mcp@latest --http --port 7500

It runs statelessly and binds to localhost only — reachable over a local HTTP port, but otherwise the same local-only, version-pinned server as the stdio mode. Point your HTTP-based client at the endpoint:

"servers": { "ui5-wcr": { "url": "http://localhost:7427/mcp" } } }
