Understanding Model Context Protocol (MCP) Server Architecture

How standardized tool endpoints enable Claude, Gemini, and ChatGPT agents to execute codebase operations.

Step-by-Step Code Migration Guide

Initialize MCP Stdio Transport Server

Create an MCP Server instance listening on standard IO or SSE for client connections.

❌ Before (Legacy Approach)

// Traditional REST API Endpoint
app.post('/api/tools/execute', (req, res) => { res.json({ result: 'done' }); });

✅ After (Optimized Architecture)

import { Server } from '@modelcontextprotocol/sdk/server/index.js';
import { StdioServerTransport } from '@modelcontextprotocol/sdk/server/stdio.js';

const server = new Server({ name: 'gitigit-mcp', version: '1.0.0' }, { capabilities: { tools: {} } });
const transport = new StdioServerTransport();
await server.connect(transport);
