Installation

In SourceWeft

  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.iron-out%2Fux-benchmark/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

run_ux_benchmark

Run UX benchmark

Returns the Iron/Out UX Score (0 to 100) for one website, using real-user Chrome UX Report (CrUX) data from the last 28 days. The score is built on five Web Vitals: TTFB (10%), FCP (15%), LCP (25%), INP (25%) and CLS (25%). Use this when the user asks how fast or user-friendly a site is for real visitors. It does not run a lab test or Lighthouse and does not load the site. Sites with too little Chrome traffic have no CrUX data and return no score. If a monthly revenue band is given, it also estimates the revenue at stake. Returns a summary and a link to the full report.

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.
