Wheel Fitment API

Overview

Wheel Fitment API is the official MCP server for accessing vehicle wheel and tire fitment data from wheel-size.com. Any MCP-compatible AI assistant can call its tools directly, letting the model decide when to use fitment information during conversations or agent workflows.

The server runs locally as the Python package wheel-size-mcp, installed via uvx, and communicates over stdio. You'll need to provide your WHEELSIZE_API_KEY through an environment variable to authenticate. The latest release is v0.5.1, published under the MIT license with source code available at driveate/wheel-size-mcp on GitHub.

Wheel Fitment API is categorized as a Development tool on mcp.site and integrates with all major MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, and Zed. If you maintain this server for driveate, you can claim this listing to verify ownership, earn the Verified badge, and ensure the information stays up to date.
