Chess MCP Server

A Model Context Protocol (MCP) server that enables AI assistants to play and analyze chess games.

Overview

This MCP server provides chess functionality through the Model Context Protocol, allowing AI assistants like Claude to:

• Play chess games with proper move validation
• Analyze positions and suggest moves
• Track game state and history
• Support standard chess notation

Installation

Prerequisites

• Python 3.8 or higher
• uvx package runner

      "command": "uvx",
      "args": [
        "--from",
        "git+https://github.com/chatkausik/Chess-mcp-server-build.git",
        "chess"
      ]
