DMC-12 Showcase

The first dealership with a live MCP server

Mark Miller Subaru runs the first public dealership MCP + A2A + UCP surface. Browse inventory, pull out-the-door pricing, or connect any MCP client and call it directly.

MCP

Model Context Protocol — structured tool calls for inventory, pricing, and availability

A2A

Agent-to-Agent — authenticated, scoped rail between Lot Watch and Mark Miller

UCP

Universal Commerce Protocol: a manifest of what the merchant sells and which capabilities an agent can call

Lot Watch's Access Scopes

inventory:read · live pricing:read · live quote:write · next chapter reservation:write · next chapter deal:handoff · next chapter

Today we read live inventory and itemized out-the-door pricing over the protocol. 30-minute quotes at asking price, soft holds, and agentic deal handoff are the locked write scopes, up next.

Verify the surface yourself: agent-card · ucp manifest · spec
