CarsXE for AI agents

CarsXE provides vehicle data lookups, covering VIN specs, recalls, market value, and history, for teams that need to verify a car before a deal. Connect it once through Arc0, and your agent, or Claude, ChatGPT and Cursor, can use it through one MCP endpoint, limited to what each user approved.

04 · AUTH AND DATA

How CarsXE connects.

Users add their CarsXE api key on Arc0 Connect. It is encrypted in the vault, never shown to the model, and each user can rotate or revoke it at any time.

The same CarsXE connection serves your agent over MCP and your own backend over REST and the proxy, so a user connects once. How Arc0 handles credentials →

07 · FAQ

CarsXE and Arc0, answered.

Q01

Can I use CarsXE with Claude, ChatGPT or Cursor?

Yes. Connect CarsXE to Arc0 once, then add your Arc0 MCP URL to Claude, ChatGPT, Cursor, Claude Code or any other remote-MCP client. Each assistant only gets the CarsXE actions you allow.

Q02

How do users connect CarsXE?

Users add their CarsXE api key on Arc0 Connect. It is encrypted in the vault, never shown to the model, and each user can rotate or revoke it at any time.

Q03

Which CarsXE actions can my agent take?

12 in total: 8 read, 4 write and 0 destructive, such as “decode OBD Code”. Your policies decide which of them each agent may call.

Q04

Can I make my agent read-only in CarsXE?

Yes. Allow read actions and deny writes in the CarsXE policy. Your agent can still look things up, and any write it attempts is blocked and logged.

Q05

Can my own backend call CarsXE too?

Yes. The same CarsXE connection is available over REST and through the Arc0 proxy, so your product and your agent share one connection per user.
