Wheel Fitment MCP Server: Bolt Pattern Data for AI Assistants
Use the ANKUSI wheel fitment data directly inside AI assistants. This free MCP (Model Context Protocol) server lets Claude, ChatGPT, Cursor and other MCP clients look up bolt pattern, center bore, factory wheel size and offset for about 10,000 vehicles. No API key and no sign-up. It serves the same records as the Wheel Fitment API and the open Wheel Fitment Dataset (CC BY 4.0).

}Example questions to ask your assistant
- What is the bolt pattern and center bore of a 2019 Toyota Camry?
- Which trucks use a
6x139.7bolt pattern? - Will a
20x9.5ET20 wheel fit a BMW M3 F80?

Bolt pattern and center bore values are cross-checked against two independent sources before release (see how we verify fitment data). Flush and maximum sizes are references, not guarantees; confirm clearance on the actual car. When an assistant uses this data, please credit ANKUSI Wheels.
