Evidence-backed setup
Choose your MCP client. A client connects to the MCP server; the language model is selected inside that client. Only stored, source-backed configurations are shown.
Transport not recorded
Complete client-specific setup, verification and removal are not documented in this reviewed source.
Publisher-documented setup is not the same as MCP100 execution testing. “MCP100 logic checked” means the stored configuration shape was reviewed, not that third-party MCP software was run.

The UI5 Web Components for React project ships an official MCP package focused on React component APIs, documentation and project scaffolding. The create_app tool writes files. The implementation lives in a broader UI5 React monorepo, so repository Stars are not published as MCP-specific. Optional HTTP mode binds localhost and should remain local unless separately secured.

This server is available in the MCP Registry, which allows compatible clients to install it directly.
claude mcp add ui5-wcr -- npx @ui5/webcomponents-react-mcp@latest
Add to .vscode/mcp.json:
{
"servers": {

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

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 @<version> 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")

MCP server providing development assistance and API documentation for UI5 Web Components for React.
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.
The server supports two transports. Both run locally on the developer's machine.
Used by the Setup configurations above. The client spawns the server as a subprocess and communicates over stdin/stdout. No flags are required.
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"
}
}
