Public MCP infrastructure · Founding dealer pilot

Retail facts.
Agent ready.

A DealershipMCP Gateway turns dealer-published vehicle inventory, availability, prices, charges, and incentives into structured MCP tools an AI agent can use without guessing.

Protocol ≠ gateway

The protocol defines the contract.
The gateway runs it.

OPEN SPECIFICATION

Dealer Agent Protocol

The portable rulebook: tool names, schemas, retail semantics, pricing disclosures, trust fields, and conformance requirements.

OPERATED INFRASTRUCTURE

DealershipMCP Gateway

The running implementation: source adapters, dealer policy, normalization, authorization, audit, and MCP responses.

Use the gateway →

Anyone can implement Dealer Agent Protocol. This gateway is one operated implementation—not the protocol itself.

01 / Capability surface

Six tools.
Zero invented facts.

The public pilot exposes six experimental retail-read tools. Each response keeps the rooftop, source, observation time, authority, and uncertainty attached; it does not claim full Core conformance.

  1. 01
    dealeragent.discovery.get_manifest

    Discover profiles, scopes, resources, and conformance evidence.

  2. 02
    dealeragent.dealer.get

    Resolve the dealer organization and its retail rooftops.

  3. 03
    dealeragent.inventory.search

    Search dealer-published vehicles with typed filters and cursors.

  4. 04
    dealeragent.inventory.get_vehicle

    Read one vehicle without treating the listing as a promise.

  5. 05
    dealeragent.inventory.verify_availability

    Return the latest evidence and require a human check until a real-time authority is connected.

  6. 06
    dealeragent.pricing.get_disclosure

    Separate advertised price, required charges, and conditional offers.

02 / Trust boundary

The adapter stays behind the line.

The Gateway connects to approved inventory sources and can add authoritative pricing and availability sources as dealers provide them. Agents receive normalized retail facts—not generic access to operational systems.

GATEWAY RULE

Source integrations remain behind the policy boundary. Agents receive only protocol-shaped retail facts.

03 / Connect

Test the contract,
not a sales pitch.

This public endpoint serves Howard Bentley Buick GMC’s dealer-authorized daily retail inventory. It exposes public vehicle facts and photos, records privacy-filtered query receipts, and never exposes customer records or dealer-private inventory age.

04 / Open project

Use it. Inspect it.
Improve it.

The open protocol and public reference materials use Apache-2.0. The operated service has a separate responsibility: securely serving enrolled dealers’ approved retail data.
