Webcomponents React MCP Server — questions

Answers built from our own checks of this server.

Why is there no uptime for Webcomponents React MCP Server?

Webcomponents React MCP Server runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the npm package @ui5/webcomponents-react-mcp was installed 1 418 times last week.

How do I connect Webcomponents React MCP Server?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It runs locally, so the command pulls @ui5/webcomponents-react-mcp straight from npm; nothing to host, nothing to sign up for.

How many people use Webcomponents React MCP Server?

The npm package @ui5/webcomponents-react-mcp was installed 1 418 times in the last week. Week over week that is +1%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is Webcomponents React MCP Server open source?

Yes — it is published under the Apache-2.0 licence, written in TypeScript, 543 stars on GitHub and 12 open issues. The source link is on this page, so you can read exactly what it does with your data before you connect it.
