**BoltPatternHQ MCP** is the official Model Context Protocol server powered by [BoltPatternHQ.com](https://boltpatternhq.com), the ultimate automotive wheel fitment database. This server empowers AI assistants (like Claude, Cursor, and Windsurf) with 100% accurate, real-time automotive wheel specifications. By exposing our extensive dataset, LLMs can now instantly retrieve precise PCD, center bore, offset, and lug nut thread sizes for over 11,500+ vehicles without hallucinating fitment data. ### Key Features * **Precise Make & Model Lookup**: Instantly retrieve the exact wheel bolt pattern (PCD) and center bore for any specific vehicle make, model, and year (1992-2026). * **Reverse Pattern Search**: Input a specific bolt pattern (e.g., "5x114.3" or "4x100") to find a comprehensive list of all vehicles that share those exact wheel specifications. * **Fitment Cross-Compatibility**: Allow AI to intelligently determine which wheels from one car will safely fit onto another by comparing offset ranges and center bore diameters. * **Hardware Specs**: Get precise thread sizes for lug nuts and wheel bolts, ensuring users know exactly what hardware is required for their wheel setup.
