[Copilot]

Adds setup instructions for configuring the Nuxt UI MCP server with GitHub Agent (GitHub Copilot).

Changes

• Added GitHub Agent section to /docs/content/docs/1.getting-started/7.ai/1.mcp.md
• Positioned after Opencode section, following existing AI assistant configuration pattern
• Includes MCP settings JSON with tools: ["*"] parameter

Configuration

Users navigate to GitHub Copilot Settings and add:

{
  "mcpServers": {
    "nuxt-ui": {
      "type": "http",
      "url": "https://ui.nuxt.com/mcp",
      "tools": ["*"]
    }
  }
}

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• pkg.pr.new
  • Triggering command: node /usr/local/bin/pnpm install (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

Original prompt

within the documentation, add a new section to explain how to add MCP within for GitHub Agent:
