Summary

Chapter 7c of the MCP server: the server is on npm (1.1.0) and in the MCP Registry, and the site documents it.

  • content/MCP.mdx (guide): install, with npx playwright install chromium; the configuration of Claude Code, of the clients with an mcpServers object (Cursor, Claude Desktop, Gemini CLI, Antigravity, with the file of each) and of VS Code (with an input for the key); the tools, resources and prompts; the CrUX key in the configuration of the client, with a note for apps opened from the Dock, which do not get the variables of the shell; and when to use Chrome DevTools MCP instead.
  • "MCP server" in the navigation after CLI, a row and a short section in "Run them with an AI agent" of the home page and the README, and links from the CLI page and cli/README.md.
  • public/llms.txt regenerated.

The paths of the configuration files come from the documentation of VS Code and Antigravity, and from guides for Cursor, Claude Desktop and Gemini CLI.

Test plan

  • check:consistency, check:emoji, test:site 44/44 and lint, locally
  • Dev server: /MCP and the home page render, with every section, the table of clients and the link to /MCP, locally
  • Preview of Vercel
  • CI

A guide page for the MCP server of the CLI: how to install it (Chromium of Playwright, which npx does not download), the configuration of Claude Code, of the clients that read an mcpServers object (Cursor, Claude Desktop, Gemini CLI, Antigravity, with the file of each) and of VS Code, the tools, resources and prompts, the CrUX key in the configuration of the client (in VS Code, an input that keeps it out of mcp.json), and when to use Chrome DevTools MCP instead. The home page, the README, the CLI page and cli/README.md link to it, and llms.txt lists it.
