Discussion Topic

Assume that we have a website that has lots of structured data, and all data is interlinked using extensive JSON-LD schemas on their pages. Some AI crawlers are using this information to build their knowledge graph.

Now, in JSON-LD you can add ConsumeActions to link to external data sources too, for example your API: you could have a page with all the articles you are selling in your shop, and then point to your API using this method:

{
  "@context": "https://schema.org",
  "@type": "CollectionPage",
  "name": "Leather Goods Collection",
  "description": "Our finest selection of leather jackets and boots.",
  "mainEntity": {
    "@type": "ItemList",
    "itemListElement": [
      {
        "@type": "ListItem",
        "position": 1,
        "url": "https://www.myshop.com/products/leather-jacket",
        "name": "Vintage Leather Jacket"
      },
      {
        "@type": "ListItem",
        "position": 2,
        "url": "https://www.myshop.com/products/leather-boots",
        "name": "Classic Leather Boots"
      }
    ]
  },
  "potentialAction": [
    {
      "@type": "ConsumeAction",
      "target": {
        "@type": "EntryPoint",
        "urlTemplate": "https://www.myshop.com/api/v1/collections/leather-goods/products",
        "contentType": "application/json"
      }
    },
    {
      "@type": "SearchAction",
      "target": {
        "@type": "EntryPoint",
        "urlTemplate": "https://www.myshop.com/collections/leather-goods/search?q={search_term_string}"
      },
      "query-input": "required name=search_term_string"
    }
  ]
}

My question is: is there a standard to connect these with a MCP server so agents know what they can do?
Is an equivalent to https://schema.org/WebAPI needed? MCPServer for example.

It would be nice if AI companies can come up with some standard for allowing this connection.
