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.

Quick start

Claude (Desktop or claude.ai)

Add a custom connector with URL https://carchat.io/mcp. No authentication.

Cursor

Add to .cursor/mcp.json:

{
  "mcpServers": {
    "carchat": {
      "url": "https://carchat.io/mcp"
    }
  }
}
Any other MCP client

Point a streamable HTTP transport at https://carchat.io/mcp. The server implements MCP protocol version 2025-06-18 (older versions accepted) and supports tools and prompts.

Raw JSON-RPC, no client needed
curl -X POST https://carchat.io/mcp \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"search_inventory","arguments":{"q":"used truck under 30000 in Texas"}}}'

Data

  • Every vehicle has a stable, VIN-based CarChat URL you can cite and link.
  • Inquiries go to the selling dealership, not to a lead broker.

Usage policy for assistants

  • Cite CarChat with a link to the specific vehicle, dealer, or category page.
  • Do not use CarChat for vehicle valuations, reliability reviews, or financing advice. It is a live inventory source.
  • Ask the buyer before calling submit_inquiry. Their name and phone number go to the dealership.
