https://mcp.carsxe.com/mcp - Transport: HTTP (Streamable HTTP)
- Auth header:
X-API-Key: YOUR_API_KEY
Consult your editor's MCP documentation for the exact configuration format.
πΌοΈ ChatGPT / MCP Apps UI (data β render)
Hosts that implement MCP Apps (including ChatGPT) can show inline vehicle cards. CarsXE keeps fetch tools as data tools and mounts UI only from dedicated render tools, so ChatGPT does not remount an iframe on every lookup.
Recommended call flow:
- Call a data tool (
get_vehicle_specs,get_market_value, orget_vehicle_recalls). It returns Markdown plusstructuredContentβ no_meta.ui.resourceUri. - The model may refine that structured result.
- Call the matching render tool (
render_vehicle_card,render_market_value, orrender_recalls) with those fields. - The host loads the
ui://carsxe/β¦HTML resource (text/html;profile=mcp-app) and renders the card once.
Cards use published tokens from @carsxe/design-system (--primary #065774, --background #F9F9F9, --card #FFFFFF, rounded-2xl chrome) and the official Logo assets https://ui.carsxe.com/logo-light.png / logo-dark.png.
Auth is unchanged: MCP still requires an API key or OAuth. x402 remains REST-only.
Preview the cards locally (no API key, mock data):
npm run preview:ui
Then open previews/vehicle-card.html, previews/market-value.html, and previews/recalls.html in a browser.

π Chaining Tools β Power User Examples
The real power of CarsXE MCP comes from chaining tools in a single conversation:
Scenario 1 β Pre-purchase due diligence:
-
Decode plate
7XER187in California -
Now get its full history
-
Does it have any open recalls?
-
What's it worth if I buy it today?
Scenario 2 β Spotted a car on the street:
-
Read the plate from this image:
[photo URL] -
Look up that plate in Texas
-
Show me photos of that car model
Scenario 3 β Mechanic / service shop:
-
Decode this VIN from the dashboard photo:
[image URL] -
Get its full specs
-
My customer says the check engine code is P0300 β what does that mean for this vehicle?
Scenario 4 β Fleet recall scan without VINs:
-
List Toyota models for 2020
-
Check recalls for a 2020 Toyota Camry
-
Submit a recalls batch for these inventory VINs:
[list] -
Check the batch status, then show results
π OAuth 2.1 (Claude.ai custom connector)
The hosted server at https://mcp.carsxe.com/mcp supports two authentication methods:
- API key (unchanged) β
X-API-Keyheader,Authorization: Bearer <api-key>, or?key=query parameter. Used by Claude Desktop /mcp-remoteand local clients. - OAuth 2.1 β used by hosted MCP clients such as the Claude.ai custom connector. Clicking Connect in Claude.ai runs a standard Authorization Code + PKCE flow: dynamic client registration (RFC 7591), browser sign-in on the CarsXE consent page, then token exchange. Access tokens (
mcp_at_*, 1 h) map to the user's CarsXE API key; refresh tokens (mcp_rt_*, 90 d) are rotated on every refresh.
Requests with no credentials get 401 with a WWW-Authenticate challenge, which is what prompts Claude.ai to start the flow.
