What it does

Once installed, your site exposes:

GET https://yoursite.com/.well-known/mcp-server

Which returns:

{
  "mcp_version": "2025-06-18",
  "name": "My Shop MCP Server",
  "endpoint": "https://yoursite.com/wp-json/mcp/v1",
  "transport": "http",
  "auth": { "type": "none" },
  "capabilities": ["tools", "resources"],
  "categories": ["e-commerce"],
  "languages": ["it"],
  "last_updated": "2026-03-25T00:00:00Z",
  "expires": "2026-09-25T00:00:00Z",
  "crawl": true
}

AI agents resolve mcp://yoursite.com and connect directly.
