Install

Claude Desktop

Add to ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows):

{
  "mcpServers": {
    "carwhere-vin": {
      "command": "npx",
      "args": ["-y", "carwhere-vin-mcp"]
    }
  }
}

Restart Claude Desktop. Type "Decode VIN 4T1BF1FK1HU381301" to test.

Cursor

Add to ~/.cursor/mcp.json (or via Cursor → Settings → MCP):

{
  "mcpServers": {
    "carwhere-vin": {
      "command": "npx",
      "args": ["-y", "carwhere-vin-mcp"]
    }
  }
}

Claude Code

claude mcp add carwhere-vin -- npx -y carwhere-vin-mcp

Windsurf / Zed / Continue / any MCP client

Use the same npx -y carwhere-vin-mcp invocation.

Hosted (no install)

If you can't install Node binaries locally, point your MCP client at the hosted Streamable HTTP endpoint:

https://www.carwhere.com/api/mcp

The same five tools are available over HTTP/JSON-RPC.

Data sources

  • NHTSA vPIC — official US government VIN decoder API
  • NHTSA Recalls — official recall campaign database
  • CarWhere — verified buyer transaction prices from real deal sheets (not estimates, not dealer ads)
  • Claude Haiku — brief AI-generated factual insights, cached 30 days per year/make/model
