Boxerbook MCP server
Boxerbook (boxerbook.com) is an open catalog of professional boxing worldwide: boxers, bouts, cards, results with sources, world titles, publisher rankings (WBC, WBA, IBF, WBO, The Ring, TBRB), the Boxerbook rating and a pre-fight forecast. The data is open under ODbL with attribution "Boxerbook".
This repository holds the public metadata of the remote MCP server and the free JSON API. The product code lives elsewhere; nothing here needs to be installed.
