Chess UCI

Overview

Chess UCI is a Model Context Protocol (MCP) server: Analyze chess positions and get best moves from UCI engines such as Stockfish or Leela. As an MCP server it plugs straight into AI assistants, exposing its functionality as tools the model can invoke on your behalf.

It runs locally: the Python package chess-uci-mcp (via uvx) speaks MCP over stdio on your machine. No credentials are required — it works out of the box. The current release is v0.2.0, published under the MIT license, with source at AnglerfishChess/chess-uci-mcp on GitHub.

You'll find Chess UCI in the Finance category here on mcp.site; it connects to Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed, and any other MCP client — see the install snippets below.
