Security note

MCP servers receive tool arguments from a conversation and may perform external actions. Review what a server can do before you enable it, and give it only the access it needs.

The registry verified the GitHub account UI5 for this listing. That does not show the account is the product's maker.

SourceWeft's checks cover whether the listing is complete and the endpoint answered; they do not review the server's code or what its tools do.

Overview

AI-generated overview

MCP server for UI5 Web Components development that lets an assistant look up component APIs, integration guides and documentation.

What you can do: Look up API docs for UI5 Web Components, including properties, slots, events and methods across the main, Fiori and AI packages. Get integration guides for React, Angular or plain JavaScript with installation, imports and examples. List all available UI5 Web Components documentation with summaries. Read the full content of a specific documentation file.
When to use it: Use it when building a frontend project with UI5 Web Components and you need component API details, integration guidance, or the official documentation at hand. Works with MCP clients such as VS Code Copilot or Claude Code.
Requirements: Local Node.js v20.17.0 or v22.9.0 and later, plus npm v8.0.0 or later; started over stdio via npx, and an MCP-compatible client. On native Windows you may need to prefix npx with cmd /c.

Before you install

Setup runs the package directly with npx -y, which downloads and executes the latest published version, so check the package source and version. The server only serves documentation and needs no accounts or keys.

Installation

In SourceWeft

Open Webcomponents Mcp Server in the dashboard and add it to a workspace.
Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

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:

json

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

{  "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`:

json

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

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

Score

50% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

Reached in the last 30 days25 pts
Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.
Auth declared10 pts
Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.
