@gebrai/gebrai v1.1.0

GeoGebra MCP Tool

A Model Context Protocol (MCP) server that enables AI models to interact with GeoGebra's mathematical software suite for creating interactive mathematical visualizations and dynamic constructions.

🎯 Overview

The GeoGebra MCP Tool bridges the gap between AI reasoning capabilities and mathematical visualization, allowing AI assistants to:

• Create geometric constructions (points, lines, circles, polygons)
• Plot mathematical functions and graphs
• Perform algebraic computations with visual representation
• Generate interactive mathematical demonstrations
• Export visualizations in various formats

🚀 Quick Start Examples

1. NPX (Recommended):

# Start the server
npx @gebrai/gebrai

# Or with custom log level
npx @gebrai/gebrai --log-level debug

2. Connect to Claude Desktop - Add to your Claude configuration:

{
  "mcpServers": {
    "geogebra": {
      "command": "npx",
      "args": ["@gebrai/gebrai"]
    }
  }
}

3. Start Creating - Ask Claude to create mathematical visualizations!

🛠️ CLI Usage

The GeoGebra MCP Tool provides a command-line interface with the following options:

Usage:
  npx @gebrai/gebrai [options]
  gebrai [options]              # if installed globally
  geogebra-mcp [options]        # alternative command

Options:
  -h, --help        Show help message
  -v, --version     Show version information
  --log-level LEVEL Set log level (error, warn, info, debug) [default: info]
  --port PORT       Set server port [default: stdin/stdout for MCP]

Examples:
  npx @gebrai/gebrai                    # Start MCP server
  npx @gebrai/gebrai --log-level debug  # Start with debug logging
  npx @gebrai/gebrai --help             # Show help

🏗️ Architecture

Core Components

1. MCP Server (src/server.ts)

   • Handles JSON-RPC 2.0 protocol
   • Routes requests to appropriate handlers
   • Manages server lifecycle

2. Tool Registry (src/tools/index.ts)

   • Manages available tools
   • Handles tool execution
   • Provides tool discovery

3. Error Handling (src/utils/errors.ts)

   • Standardized error responses
   • JSON-RPC error codes
   • Comprehensive error logging

4. Logging (src/utils/logger.ts)

   • Structured logging with Winston
   • Configurable log levels
   • Development and production modes

Design Principles

• Type Safety: Full TypeScript implementation with strict mode
• Error Handling: Comprehensive error handling and validation
• Modularity: Clean separation of concerns
• Testability: Extensive test coverage
• Extensibility: Easy to add new tools and features
