BetterChess is a remote MCP server that gives an AI agent 3 tools, among them chess_analyse, chess_attacks, chess_review. It answers at https://mcp.betterchess.co over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 10 of 10 times since 5 September 2026; the last check, on 18 October 2026, succeeded.
Chess MCP for Claude: engine analysis, attack maps, game review. One URL, no install.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
chess_analyse | Returns an engine evaluation of a chess position: the strongest candidate moves with their scores, and the position's checkable facts — side to move, whether that side is in check, undefended pieces and the pieces attacking them, and the ma Inputs: fen, pgn, moves, multipv, considering |
chess_attacks | Returns the exact list of squares attacked by the piece standing on a given square in a chess position, together with that piece's type and colour. Returns an empty list when the square is unoccupied. Accepts a FEN, a PGN, or a list of SAN Inputs: fen, pgn, moves, square |
chess_review | Replays a finished game ply by ply with the engine and returns the moves where the evaluation swung by more than a threshold (default 1.5 pawns). Each entry gives the move number, the side that moved, the move played, the engine's preferred Inputs: pgn, moves, colour, threshold |

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://mcp.betterchess.co. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.
