How It Works

Understanding the architecture and flow of Gemini MCP Tool.

Architecture Overview

Claude Desktop/Code  →  MCP Protocol  →  Gemini MCP Tool  →  Gemini CLI  →  Gemini AI
                     ←                ←                    ←              ←

Key Components

1. MCP Server

• Implements Model Context Protocol
• Handles communication with Claude
• Manages tool registration and execution

2. Gemini CLI Integration

• Executes gemini commands via subprocess
• Handles file paths and context
• Manages response parsing

3. Tool Registry

• analyze: File analysis and questions
• sandbox: Safe code execution
• help: Show available commands
• ping: Test connectivity

Request Flow

1. User Input → Claude Desktop receives slash command or natural language
2. MCP Protocol → Claude sends request to MCP server
3. Tool Execution → Server maps to appropriate Gemini CLI command
4. Gemini Processing → CLI processes with Gemini's 2M token context
5. Response → Results returned through MCP protocol to Claude

Why This Architecture?

• Separation of Concerns: Each component has a single responsibility
• Extensibility: Easy to add new tools or modify behavior
• Reliability: Error handling at each layer
• Performance: Async operations where possible
