CarChat MCP Server
Live US dealership vehicle inventory for AI assistants, over the Model Context Protocol.
Endpoint: https://carchat.io/mcp (streamable HTTP)
Auth: none. Free to use, no API key.
Discovery card: https://carchat.io/.well-known/mcp.json
CarChat (carchat.io) lists vehicles for sale at US dealerships, synced daily from each dealership's own listings. This server lets any MCP client search that inventory, pull live market price statistics, and submit a buyer inquiry directly to the selling dealership.
