Chessigma is a chess analysis and puzzle platform that lets users analyze games, identify openings, solve daily puzzles, and estimate Elo changes. Its tools run largely client-side with Stockfish in the browser and also provide public developer access for chess-related data and utilities.
Chessigma exposes two public integration surfaces: a no-auth REST API with an OpenAPI spec and a no-auth MCP server over Streamable HTTP; no GraphQL API or CLI was found.
