Custom MCP Server Development: Complete Implementation Guide

Building custom Model Context Protocol (MCP) servers allows you to expose your data, tools, and services to Large Language Models in a standardized way. This comprehensive guide walks you through creating production-ready MCP servers from setup to deployment.

Production Deployment

Prerequisites and Setup

Required Knowledge

Familiarity with JavaScript/TypeScript or Python
Understanding of APIs and server-client communication
Basic knowledge of JSON-RPC protocol concepts

Environment Setup

TypeScript/Node.js Setup:

# Create new project
mkdir my-mcp-server
cd my-mcp-server
npm init -y

# Install MCP SDK
npm install @modelcontextprotocol/sdk
npm install -D typescript @types/node

# Create TypeScript config
npx tsc --init

Python Setup:

# Create virtual environment
python -m venv venv
source venv/bin/activate  # On Windows: venv\Scripts\activate

# Install MCP SDK
pip install mcp

# Create project structure
mkdir my-mcp-server
cd my-mcp-server

Understanding MCP Server Architecture

Core Components

MCP servers expose three main primitives:

Resources: Data sources that can be read by the LLM
Tools: Functions that can be executed to perform actions
Prompts: Reusable interaction templates

Server Lifecycle

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

// Start server
await server.connect(transport);

Creating Tools

Advanced Server Patterns

Middleware Pattern

class MiddlewareMCPServer {
  private middlewares: Array<(request: any, next: () => Promise<any>) => Promise<any>> = [];

  use(middleware: (request: any, next: () => Promise<any>) => Promise<any>) {
    this.middlewares.push(middleware);
  }

  private async executeMiddleware(request: any, handler: () => Promise<any>) {
    let index = 0;

    const next = async (): Promise<any> => {
      if (index >= this.middlewares.length) {
        return await handler();
      }

      const middleware = this.middlewares[index++];
      return await middleware(request, next);
    };

    return await next();
  }

  setupMiddlewareHandlers() {
    // Logging middleware
    this.use(async (request, next) => {
      console.log(`[${new Date().toISOString()}] ${request.method}`);
      const start = Date.now();
      
      try {
        const result = await next();
        console.log(`[${new Date().toISOString()}] ${request.method} completed in ${Date.now() - start}ms`);
        return result;
      } catch (error) {
        console.error(`[${new Date().toISOString()}] ${request.method} failed: ${error.message}`);
        throw error;
      }
    });

    // Rate limiting middleware
    this.use(async (request, next) => {
      if (!await this.checkRateLimit(request)) {
        throw new Error("Rate limit exceeded");
      }
      return await next();
    });

    // Apply middleware to handlers
    this.server.setRequestHandler(CallToolRequestSchema, async (request) => {
      return await this.executeMiddleware(request, async () => {
        return await this.handleToolCall(request);
      });
    });
  }

  private async checkRateLimit(request: any): Promise<boolean> {
    // Implement rate limiting logic
    return true;
  }

  private async handleToolCall(request: any) {
    // Original tool handling logic
    return { content: [{ type: "text", text: "Tool executed" }] };
  }
}

Testing and Debugging

Unit Testing

import { jest } from '@jest/globals';

describe('CustomMCPServer', () => {
  let server: CustomMCPServer;

  beforeEach(() => {
    server = new CustomMCPServer();
  });

  test('should handle calculate tool', async () => {
    const result = await server.handleCalculate({ expression: "2 + 2" });
    
    expect(result.content[0].text).toBe("Result: 4");
  });

  test('should handle weather tool', async () => {
    const result = await server.handleGetWeather({ city: "London" });
    
    expect(result.content[0].text).toContain("Weather in London");
  });

  test('should list available tools', async () => {
    const tools = await server.listTools();
    
    expect(tools.tools).toHaveLength(2);
    expect(tools.tools[0].name).toBe("calculate");
    expect(tools.tools[1].name).toBe("get_weather");
  });
});

Integration Testing

import { Server } from "@modelcontextprotocol/sdk/server/index.js";
import { TestTransport } from "@modelcontextprotocol/sdk/server/test.js";

describe('MCP Server Integration', () => {
  test('should handle full request/response cycle', async () => {
    const server = new CustomMCPServer();
    const transport = new TestTransport();
    
    await server.start(transport);
    
    // Send list tools request
    const toolsResponse = await transport.request({
      method: "tools/list",
      params: {}
    });
    
    expect(toolsResponse.result.tools).toBeDefined();
    
    // Call a tool
    const callResponse = await transport.request({
      method: "tools/call",
      params: {
        name: "calculate",
        arguments: { expression: "5 * 6" }
      }
    });
    
    expect(callResponse.result.content[0].text).toBe("Result: 30");
  });
});

  };

  setupHealthCheck() {

      async () => ({
        status: "healthy",
        uptime: Date.now() - this.metrics.startTime,
        metrics: {
          totalRequests: this.metrics.requestCount,
          totalErrors: this.metrics.errorCount,
          averageResponseTime: this.getAverageResponseTime()
        }
      })
    );
  }

  private getAverageResponseTime(): number {
    if (this.metrics.responseTime.length === 0) return 0;
    
    const sum = this.metrics.responseTime.reduce((a, b) => a + b, 0);
    return sum / this.metrics.responseTime.length;
  }

  private trackMetrics(fn: Function) {
    return async (...args: any[]) => {
      const start = Date.now();
      this.metrics.requestCount++;
      
      try {
        const result = await fn.apply(this, args);
        this.metrics.responseTime.push(Date.now() - start);
        return result;
      } catch (error) {
        this.metrics.errorCount++;
