MostExpensiveWatches MCP MCP server

An official MCP server for the MostExpensiveWatches platform that provides AI agents with access to live inventory of ultra-luxury watches, over 1,000 documented auction records with primary-source citations, AI-written reference descriptions, and an upcoming auction calendar. It enables agents to answer pricing questions and track high-end horology assets using real-time data from vetted resellers and major auction houses.
