Claude Code MCP

Extend Claude Code with unlimited external integrations through the Model Context Protocol - the universal standard for AI-tool connections

MCP Integration Deep Dive

Master the Model Context Protocol to extend Claude Code with unlimited external integrations

What is MCP?

The Universal Protocol for AI-Tool Integration

MCP (Model Context Protocol) is an open protocol that standardizes how AI applications connect to external data sources and tools. Think of MCP as the "USB-C for AI" - just like USB-C provides a universal way to connect devices, MCP provides a universal way for AI models to connect to different tools and services.

Key Benefits:

  • • Standardized integration approach
  • • Secure and controlled access
  • • Extensible and modular design
  • • Enterprise-ready architecture

Universal Protocol

Standardized way for AI applications to connect with external data sources and tools

Data Integration

Connect to databases, APIs, file systems, and enterprise tools seamlessly

Secure Architecture

Built-in security controls with access management and authentication

Real-time Processing

Live data access and real-time tool execution for dynamic workflows

MCP Architecture

1

Client-Server Architecture

MCP uses a client-server model where Claude Code acts as the client

  • Hosts (LLM applications) initiate connections
  • Clients maintain 1:1 connections with servers
  • Servers provide context, tools, and prompts
2

Transport Layer

Multiple transport mechanisms for different deployment scenarios

  • Stdio transport for local processes
  • HTTP with SSE for web services
  • Custom transports for specific needs
3

Security Model

Built-in security controls and access management

  • Authentication and authorization
  • Input validation and sanitization
  • Resource access controls

Custom MCP Server Development

Build your own MCP servers for specific integrations

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

const server = new Server({
  name: "custom-server",
  version: "1.0.0"
}, {
  capabilities: {
    resources: {},
    tools: {}
  }
});

// Define tools
server.setRequestHandler(CallToolRequestSchema, async (request) => {
  const { name, arguments: args } = request.params;
  
  switch (name) {
    case "query_database":
      return await queryDatabase(args.query);
    case "send_notification":
      return await sendNotification(args.message);
    default:
      throw new Error(`Unknown tool: ${name}`);
  }
});

// Start server
const transport = new StdioServerTransport();
await server.connect(transport);
