Webcomponents React MCP Server

Webcomponents React MCP Server runs locally from a Node.js package published to the npm registry: @ui5/webcomponents-react-mcp version 2.27.2. It speaks MCP over stdio, so the client starts it as a program and talks to it through standard input and output. It needs Node.js; clients usually start it with npx — the usual command is npx -y @ui5/webcomponents-react-mcp@2.27.2.

Webcomponents React MCP Server runs locally from a Node.js package published to the npm registry: @ui5/webcomponents-react-mcp version 2.25.1. The package starts a local server that speaks MCP over Streamable HTTP; the client then connects to it by URL (the entry names npx as the runtime).

In the mcpServers JSON format that many desktop and editor MCP clients read, the entry looks like this (placeholders in angle brackets):

{
  "mcpServers": {
    "webcomponents-react-mcp-server": {
      "command": "npx",
      "args": [
        "-y",
        "@ui5/webcomponents-react-mcp@2.27.2"
      ]
    }
  }
}
