apiauto-mcp: Encar, Che168, Copart and IAAI used cars for Claude, Cursor and other MCP clients

A read-only MCP server that lets an AI assistant search used-car listings from Encar (South Korea), Che168 (China), and Copart and IAAI auctions (USA). It runs on your machine over stdio and calls the apiauto.space API.

Unofficial: apiauto.space is an independent service, not affiliated with these sources.

Free demo: 1 day, 100 requests, up to 20 cars per request, all 3 markets. The key comes in Telegram from @apiautospace_bot, no card. Paid plans start at $59 a month: Pricing.

Quick start

Node 20.19 or newer. Claude Desktop (Settings → Developer → Edit Config) and Cursor (.cursor/mcp.json) take the same block:

{
  "mcpServers": {
    "apiauto": {
      "command": "npx",
      "args": ["-y", "apiauto-mcp@0.1.0"],
      "env": { "APIAUTO_API_KEY": "au_live_your_key" }
    }
  }
}

Claude Code:

claude mcp add apiauto --env APIAUTO_API_KEY=au_live_your_key -- npx -y apiauto-mcp@0.1.0

On Windows, use cmd /c npx -y apiauto-mcp@0.1.0. With an exact version, updates reach you only when you change it. Keep a config with your key out of git.

Ask: "Find a Toyota on Che168 with photos." A real search_cars result, shortened:

  } ] },
  "meta": { "records_charged": 1, "records_returned": 1, "has_more": true, "data_age_seconds": 1514 }
}

Tools

Nothing pages by itself: pass next_cursor as cursor. The API's live US search is left out on purpose, as it spends a separate paid counter.

Units and gotchas

Mileage is in kilometres, US miles are converted. price is in KRW, CNY or USD, price_usd at the ECB daily rate. us has no filter by auction, and one page can hold lots of just one: another sort usually brings the other.

Data freshness

Each market is a copy, refreshed hourly by target, and can be hours old. get_markets and every result show the real age.

Limits

• Your client may not ask first. Paid tools carry readOnlyHint because they change nothing, so a client may run them without confirmation, yet each call spends quota. Check your auto-approval settings.

• Optional cap: APIAUTO_MAX_RECORDS_PER_SESSION=500 in env stops paid tools after that many records in one server process.

• Costs are stated in every paid result: records_charged, records_returned, quota left. Records left out of an oversized page stay charged; omitted_ids names them, and each get_car costs 1 more.

• Unknown outcomes are not repeated. After a lost connection, a timeout, or a 500, 502 or 504, a paid request may be charged already, so it is not retried and the error says to check get_usage.

Pricing

Enterprise terms are by agreement. Current pricing.

Working in someone else's repository

npx looks in the current folder first, so a project's node_modules/.bin or .npmrc can replace what starts under this name, with your key in its environment. If your client starts servers from folders you do not trust, install a fixed version globally and run it by absolute path:

npm install --global --ignore-scripts apiauto-mcp@0.1.0
npm root --global

{ "command": "node", "args": ["/absolute/path/from/npm-root/apiauto-mcp/dist/index.js"], "env": { "APIAUTO_API_KEY": "au_live_your_key" } }

Security

The key is read only from APIAUTO_API_KEY, sent only in a header and removed from results, errors and logs. Requests go only to https://api.apiauto.space/v1/...; no tool takes a URL, redirects are not followed. No shell, eval, disk writing or telemetry; dependencies are locked by npm-shrinkwrap.json.

Listings are untrusted text. Results keep it inside data under a notice not to follow it. Hidden Unicode, Markdown images and links, and foreign URLs become [link removed]; a bare domain without a scheme stays as text. This lowers the risk of prompt injection and cannot remove it.
