# The standards that let agents use the web.

One article per standard, written from the spec. And a live probe: give it a domain, get back what it publishes for agents. New here? Start with [what the agentic web is](/agentic-web/).

## The wiki

82 standards across nine steps: discover, identify, permit, read, act, coordinate, pay, present, account. Every claim sourced.

[See all articles](/map/)[Data & API](/data/)

## Live probe over MCP

Give it a domain. Get back what it publishes for agents.

```
{ "origin": "shopify.com",
  "found":    { "ucp": …, "llms-txt": … },
  "absent":   { "ard": …, "a2a": … },
  "skipped":  { "ap2": "needs-credentials" },
  "coverage": { "discover": ["llms-txt"], "act": ["ucp"] } }
```

agenticweb.wiki is a reference for the standards that let software agents use the web: how an agent finds what a site offers, proves who it is, learns what it may do, reads, acts, coordinates with other agents, pays, shows a person the result, and is held to account. Each article is written from the primary specification with a numbered reference for every claim.

Every article is served three ways at one address: HTML, [Markdown](/protocols/mcp/index.md) and [JSON](/protocols/mcp/index.json). The dataset is on the [data page](/data/), indexed in [llms.txt](/llms.txt), and declared in the [ARD manifest](/.well-known/ard.json), which also lists the MCP server.

GET /protocols/mcp/index.json

```
{
  "id": "mcp",
  "name": "Model Context Protocol",
  "category": "act",
  "native_status": "Active open specification, current da…",
  "spec_url": "https://modelcontextprotocol.io/specification/2026-07-28/index",
  "probe": {
    "method": "POST",
    "path": "{endpoint}/mcp"
  },
  "evidence": [
    {
      "claim": "Canonical dated specification is 2026…",
      "url": "https://modelcontextprotocol.io/specification/2026-07-28/index"
    }
  ]
  // …
}
```

Every article: HTML · Markdown · JSON at the same address.
