Chess Goat for AI agents

Chess Goat reads public chess.com games and turns them into a player's habits, results and lessons. AI assistants use it through the MCP server below. The public tools are free and need no key or account.

MCP server

Streamable HTTP at https://trychessgoat.com/mcp. Server card.

No sign-in: goat_card, game_history, favorite_openings, course_map, lessons_for_my_games, lesson and lesson_puzzles for the free lessons, show_position (an interactive board, MCP Apps) and goat_report.
With the user's own connection (OAuth 2.1 with PKCE, dynamic client registration): every Goat Pass lesson, record_lesson progress and my_report for a purchased Goat Report. See auth.md.

ChatGPT

Chess Goat is a ChatGPT app: lessons on interactive boards, built from the player's latest games. See how to use it in ChatGPT.

Rules

Show chess.com data as public game data, never as an endorsement by the player. Don't build lists that rank or shame players, and respect opt-outs. The site's own card endpoints are rate-limited and are not a public API. Questions: hello@trychessgoat.com.
