Chessigma MCP server

Chess tools for Claude, ChatGPT and any MCP client, from Chessigma: opening guides, the opening behind any moves, position and game facts, review links for Chess.com and Lichess games, the daily puzzle and Elo estimates. Read-only, no account, no sign-in.

The server runs on chessigma.com, so there is nothing to install. This repository holds its public description and the server.json published to the official MCP Registry.

Tools

ToolWhat it does
get_opening_guideChessigma's guide to an opening by name: main line, key variations and the ideas for each side. Popular openings have a full guide; any of about 3,700 catalogued names returns its ECO code and moves.
identify_openingNames the opening of a move sequence or PGN: ECO code, how long it followed theory, and the first move that left it.
analyze_positionReads a FEN: side to move, check, mate or stalemate, every legal move, the material count and the opening name.
analyze_gameSummarizes a PGN: players, result, opening, how the game ended and the final position.
review_online_gameTurns a public Chess.com live game or Lichess game link into a link to its move-by-move review on Chessigma.
get_daily_puzzleToday's puzzle, or any day's since 1 January 2024: the position, the solution and a link to play it.
calculate_eloEstimates the rating change after one game with the Elo formula, with K-factor defaults for FIDE, Chess.com and Lichess.

The tools state facts from the rules of chess, an opening catalogue and Chessigma's puzzle archive; they do not run an engine. For engine analysis, their links open the Chessigma analysis board, where Stockfish runs in your browser.
