概覽

AI 產生的概覽

一個遠端西洋棋參考伺服器，讓助理辨識開局、讀取 FEN 與 PGN 局面、取得每日謎題並估算 Elo 變化。

功能
Chessigma 透過 Streamable HTTP 提供七個唯讀西洋棋工具。get_opening_guide 依開局名稱回傳指南，包含主線、關鍵變化與雙方思路，約 3,700 個已編目名稱還會回傳 ECO 代碼與著法。identify_opening 為著法序列或 PGN 命名開局，analyze_position 讀取 FEN（輪到哪一方、將軍、將死或逼和、所有合法著法、子力計數、開局名稱），analyze_game 摘要 PGN，review_online_game 把公開的 Chess.com 或 Lichess 對局連結轉為 Chessigma 覆盤連結，get_daily_puzzle 回傳 2024 年 1 月 1 日以來的謎題，calculate_elo 以 FIDE、Chess.com 與 Lichess 的 K 係數預設值估算等級分變化。這些工具陳述來自西洋棋規則、開局目錄與謎題庫的事實，並不執行引擎。
適用情境
適合需要開局名稱與指南、從 FEN 或 PGN 快速取得局面或對局資訊、每日謎題或 Elo 變化估算，且不想安裝任何東西的情況。不適合引擎級分析，伺服器會連結到瀏覽器中的棋盤進行這類分析。
執行需求
遠端 MCP 伺服器，使用文件提供的 Streamable HTTP 端點，無需安裝。未宣告需要帳號、登入、API 金鑰或環境變數。可在 Claude、Claude Code、Cursor、VS Code、ChatGPT 及其他支援遠端 HTTP 伺服器的 MCP 用戶端中使用。
安裝前請注意
唯讀：執行時不寫入資料、不呼叫 AI 模型、不抓取其他網站，輸入也不會被儲存。為進行速率限制，每個請求的時間、方法、路徑、IP 位址與使用者代理會被記錄，所有呼叫方共用每分鐘 300 次請求。傳送給 review_online_game 的對局連結必須是公開的 Chess.com 或 Lichess 對局。

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.
