Agents can partly use this site

An agent can read this site and get some way through it, with friction. The points still on the table are listed below, largest first.

Three fixes worth doing first

Ordered by the points still on the table. Each one comes from a documented check and, where it exists, with the code that fixes it.

01An MCP endpoint an agent can reach

+7 pts

No MCP endpoint or server card responds.

How to fix it Publish a server card at /.well-known/mcp.json pointing at your endpoint, and make sure robots.txt does not disallow the path it points at.

Model Context Protocol

02Agentic payment rails

+3 pts

This is a shop, and no agent-payable rail is advertised.

How to fix it Evaluate x402, the Agentic Commerce Protocol and the Universal Commerce Protocol against your payment provider, then publish the discovery document for whichever you adopt.

03document.modelContext is in use

+3 pts

WebMCP tooling is loaded but no registration was observed in the served code.

How to fix it Register your two or three most valuable actions as tools with document.modelContext.registerTool. Start read-only. The polyfill lets you ship before the browser support is universal.

await document.modelContext.registerTool({
  name: "search_products",
  description: "Search the catalog by free text and optional filters.",
  inputSchema: {
    type: "object",
    properties: { query: { type: "string", description: "Free-text search term" } },
    required: ["query"],
  },
  annotations: { readOnlyHint: true },
  execute: async ({ query }, { signal }) => {
    const res = await fetch(`/api/search?q=${encodeURIComponent(query)}`, {
      credentials: "same-origin",
      signal,
    });
    return { content: [{ type: "text", text: JSON.stringify(await res.json()) }] };
  },
});

Your first WebMCP tool, matched to this page

The crawl found a a shop on this site, so the example below registers that as a tool an agent can call. Paste it, point it at your own endpoint, and the page stops being guessed at and starts being called.

registerTool

// Register the first tool an agent can call on this page.
// Works today with the polyfill: npm install @mcp-b/global
await document.modelContext.registerTool({
  name: "search_products",
  description: "Search the product catalogue by free text. Returns name, price and a link per match.",
  inputSchema: {
    type: "object",
    properties: { query: { type: "string", description: "Free-text search term" } },
    required: ["query"],
  },
  annotations: { readOnlyHint: true },
  execute: async ({ query }, { signal }) => {
    const res = await fetch(`/api/products?q=${encodeURIComponent(query)}`, { signal });
    return { content: [{ type: "text", text: JSON.stringify(await res.json()) }] };
  },
});

.well-known/webmcp

{
  "name": "armorathletics.com",
  "description": "Return a short summary of this site and links to its main sections.",
  "tools": [
    {
      "name": "search_products",
      "description": "Search the product catalogue by free text. Returns name, price and a link per match."
    }
  ],
  "pages": [
    "https://armorathletics.com/"
  ]
}

The manifest at /.well-known/webmcp is the convention ChatGPT Desktop reads to list site tools. It is not part of the score yet; the registered tool above is.

Agent Readiness Check

The full report, plus a re-check in 30 days

Every check with the evidence it was judged on and the code that fixes it, sent as a link that always re-scans. In 30 days we scan again and tell you what moved.

  • All checks, pass by pass, with the exact header, count or path behind each verdict
  • Copy-paste fixes generated from your own markup
  • A re-check in 30 days with the difference, confirmed by you with one click

One email with the report, one re-check after you confirm it, and nothing else unless you ask. No account. Five reports per company per day. What we do with the address.

Agent Tracking

You know whether agents can read this site. Want to know what they do with it?

One line of script records which assistants send visitors, which pages they fetch, which WebMCP tools they call and whether they finish. No cookies, no personal data, hosted in Germany. The check score shows up in the dashboard and is re-scanned monthly.
