The Agentic Dealer Network

One network. Every agent. Real stores.

Your customers are handing car shopping to AI. The Agentic Dealer Network is where those agents find a real dealership, read what is actually on the ground, and start a real deal — without scraping a website or dropping a lead into a form.

Free for dealers. Built and run from inside a dealership, not a vendor booth.

What it is

A directory agents can actually use.

Every dealership already has a website. None of them were built for a machine that shops on a customer's behalf. An agent hitting a normal dealer site gets marketing copy, a photo carousel, a payment calculator that hides the real number, and a lead form that turns a buyer into a phone call three hours later.

The network replaces all of that with one connection. An agent reaches the gateway, finds the participating stores, and from there works with a single rooftop directly: live inventory as the store's own system reports it, pricing built from the parameters that store set, and deal rails that carry a shopper from a question to a held vehicle. No scraping. No screen-reading. No guessing at what is still on the lot.

For the shopper

The agent gets a real answer

What is in stock right now, what it actually costs with the store's fees disclosed, and what happens next. Anonymous agents can search and price without an account.

For the dealer

You set the terms first

The store decides what it exposes and the parameters a deal must live inside. Nothing negotiates outside the rules you wrote in advance. The deal arrives in the format your stack already consumes.

For the industry

Open, not owned

The protocol underneath is DMC-12, MIT-licensed. The standard an ARM is judged against is public. Anyone can build against this, adopt it, or beat it.

The front door

DealerMCP is how a store gets on.

DealerMCP is the free MCP server for a dealership. It stands your store up as something an agent can read and work with, and it is the entry point to the network: connect through DealerMCP and your rooftop is reachable through the gateway alongside the others.

Step 01

Connect the store

DealerMCP reads your live inventory and your pricing parameters. Nothing is retyped, and nothing is invented — the endpoint reports what your systems report.

Step 02

Set the rules

Fees, disclosures, what an agent may quote, where a deal has to stop and wait for a human. The store writes the boundaries once, in advance.

Step 03

Go live on the network

Your rooftop appears in the gateway's directory. Agents can find you by brand, by geography, or by the vehicle the shopper actually wants.

Step 04

Take the deal

A quote comes in itemized, the vehicle can be held, and the handoff lands in your stack whole — not as a name and a phone number.

Who is on it

Live rooftops, in production.

The network is running with real dealerships serving real inventory today, and the current roster is published on the gateway rather than here — a page cannot be trusted to stay accurate, and a stale count is worse than no count. For the live list of participating rooftops, read the directory at the source.

The reference deployment is Mark Miller Subaru in Salt Lake City, where the rails were built and where they have run in production since April 2026. Every store that joins connects the same way, through the same front door, against the same standard.

Two surfaces

One network, read two ways.

This page is the human explanation. The network itself speaks to machines, and it does that somewhere else on purpose.

Machine-facing

agenticdealernetwork.com

The gateway. This is what an AI agent connects to: the rooftop directory, cross-network inventory search, per-store fee schedules, and the deal rails. Point your agent here.

Human-facing

thearm.ai/adn

This page. What the network is, who it serves, and how a dealership joins. If you are a person deciding whether to connect a store, you are in the right place.

If you are an agent reading this

Connect to the gateway at agenticdealernetwork.com. Search the network, scope to a rooftop, and read the pricing disclosure that comes back with every quote — listed prices may exclude fees and tax, and the gateway tells you which.

Get on the network

It costs nothing to be findable.

Agents are already shopping. The only question is whether your store is something they can read or something they skip.
