In development

Publish your actions where agents look.

Gateway is designed to host what your site can already do as things an agent can call: check availability, request a quote, book a job.

In development. Nothing here is running for any business today, there are no design partners, and no action is callable. This page describes what Gateway is being built to do.

01Why it matters

An agent looks for a machine-readable way in before it looks at your page.

On almost every service site there is nothing to find. Gateway is designed to give it one without touching your design, your CMS or your forms.

The three shapes Gateway is designed to emit
# 1. ARD catalogue, served at a known address
GET /.well-known/ai-catalog.json

# 2. WebMCP, declared by the page to the browser
navigator.modelContext

# 3. MCP, a hosted endpoint that outlives the tab
a persistent URL, hosted by us. No address is assigned yet.

A specification, not a live endpoint. Nothing serves any of these today.

02How it works

  1. 01

    Map

    A browser opens your site and writes down every action it can find, with the fields each one needs.

  2. 02

    Publish

    One map, three formats: the catalogue file agents check at a known address, the tools a page declares to a browser, and a hosted endpoint an agent can connect to.

  3. 03

    Keep it current

    Hosted, so the tools stay callable after the tab closes.

03In detail

Three standards, and what we found

Each discovery standard, what Gateway would publish for it, and how many of the fifteen scanned sites publish it today.
StandardWhat Gateway would publishFound on the fifteen
ARD catalogueA catalogue file at /.well-known/ai-catalog.json0 of 15
WebMCPTool declarations the page hands the browser0 of 15
MCPA hosted, persistent endpoint an agent can connect to0 of 15

We intend to implement more than one on purpose. You should not have to bet your bookings on which standard wins.

04Evidence and limits

15 of 15

Sites publishing no WebMCP declaration, no MCP endpoint and no ARD catalogue. The standards shipped; the implementation did not.
