Webcomponents MCP server

UI5 Web Components MCP Server

A Model Context Protocol server for UI5 Web Components development.

Requirements

• Node.js Version v20.17.0, v22.9.0 or higher
• npm Version v8.0.0 or higher
• An MCP client, such as VS Code (GitHub Copilot), Claude Code, Codex, or any other MCP-compatible client

Setup

Standard Configuration for Most Clients

This configuration works for most MCP clients:

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

Special configuration for native Windows On native Windows (not WSL), you might need to prefix npx with cmd /c:

{
  "mcpServers": {
    "@ui5/webcomponents-mcp-server": {
      "type": "stdio",
      "command": "cmd",
      "args": ["/c", "npx -y @ui5/webcomponents-mcp-server"]
    }
  }
}

Specific MCP Clients

Besides the general configuration outlined above, some MCP clients offer shortcuts for installing MCP servers.

VS Code

code --add-mcp '{"name":"@ui5/webcomponents-mcp-server","type":"stdio","command":"npx","args":["-y","@ui5/webcomponents-mcp-server"]}'

Claude Code

claude mcp add --transport stdio --scope user ui5-webc-mcp-server -- npx -y @ui5/webcomponents-mcp-server

Codex

codex mcp add --transport stdio ui5-webc-mcp-server -- npx -y @ui5/webcomponents-mcp-server
