Connects Claude to historical and live collector car auction data from Bring a Trailer, Cars & Bids, Hagerty, RM Sotheby's, and other major platforms. You get completed auction results, active listings, bid trails, and market pricing statistics through a remote streamable HTTP endpoint. Reach for this when you need an AI agent to answer questions about classic car values, compare sale histories across vehicles, or analyze market trends without manually scraping auction sites. Uses OAuth for authentication, with API key fallback for tools that don't support it. The data coverage spans multiple auction houses, so you can query across platforms in a single integration.
Old Cars Data exposes collector-car auction history, live listings, bid trails, and market statistics through a remote Model Context Protocol (MCP) server.

Transport: Streamable HTTP
Old Cars Data supports OAuth-based authentication for compatible MCP clients. Developer tools that do not support OAuth may use an Old Cars Data API key where the client allows custom authorization headers.
Coverage includes Bring a Trailer, Cars & Bids, Hagerty, PCAR Market, All Collector Cars, Gooding & Co, and RM Sotheby's.
