🚀 MCP Project - Model Context Protocol

MCP (Model Context Protocol) provides a unified interface for managing context information flow in AI applications, solving common problems in existing systems.

🚀 Quick Start

Installation

npm install mcp-typescript mcp-zod mcp-communication-adapters

Start the Server

npm run start:server

✨ Features

1. Project Goals

MCP (Model Context Protocol) aims to provide a unified interface for managing context information flow in AI applications. By standardizing data formats and communication protocols, MCP solves the common problems of inconsistent context and difficult maintenance in existing systems.

2. Core Functions

• Unified Context Management: Ensures that all components can access and update context data in a consistent manner.
• Scalability: Supports multiple data formats and communication protocols, facilitating the integration of different systems.
• High Reliability: Guarantees stability in critical tasks through redundant design and error recovery mechanisms.

3. Technology Selection

• TypeScript: Provides static type checking to reduce runtime errors.
• Zod: Used for data validation to ensure the correctness of data structures.
• Express: Builds efficient HTTP servers.
• Kafka: Handles high - throughput message passing.

4. Core Components

(1) Context Manager

Responsible for maintaining the current context state and providing interfaces for other modules to read and write.

(2) Data Converter

Supports automatic conversion of multiple data formats to ensure compatibility.

(3) Communication Adapter

Implements the adaptation of different protocols (such as HTTP, WebSocket) for easy integration.

5. Design Principles

• Loose Coupling: Maintains the lowest dependency relationship between components.
• Scalability: Designed to easily add new functions and modules.
• High Availability: Ensures that the system can continue to run in case of partial failures.

6. Implementation Details

(1) Data Model

All data is defined as TypeScript interfaces and verified by Zod to ensure data integrity and correctness.

import { z } from 'zod';

export interface Context {
    id: string;
    timestamp: Date;
    data: Record<string, any>;
}

const contextSchema = z.object({
    id: z.string().min(1),
    timestamp: z.date(),
    data: z.record(z.any())
});

export const validateContext = (data: unknown): Context => {
    try {
        return contextSchema.parse(data);
    } catch (error) {
        throw new Error('Invalid context data');
    }
};

(2) Communication Protocol

Supports multiple transport protocols and is extended through the adapter design pattern.

export abstract class Adapter {
    abstract send(data: unknown): Promise<void>;
    abstract receive(): Promise<unknown>;
}

📦 Installation

Install Dependencies

npm install mcp-typescript mcp-zod mcp-communication-adapters

Start the Server

npm run start:server

💻 Usage Examples

Basic Usage

import { Context } from 'mcp-typescript';
import { validateContext } from './utils/validation';

const context = {
    id: '123',
    timestamp: new Date(),
    data: { user_id: '456' }
};

try {
    const validatedContext = validateContext(context);
    // Use validatedContext for subsequent processing
} catch (error) {
    console.error('Validation failed:', error.message);
}

MCP Project Overview

The above - mentioned core functions, technology selection, core components, design principles, and implementation details are all part of the MCP project overview.

MCP Technical Details

1. Data Model Design

All data is defined by TypeScript interfaces and strictly verified by Zod to ensure data consistency within the system.

import { z } from 'zod';

export interface RequestContext {
    id: string;
    user: User;
    metadata: Record<string, unknown>;
}

export interface User {
    id: string;
    name: string;
    email?: string;
}

2. Communication Mechanism

Supports multiple protocols and is extended through a plug - in design.

import { HttpAdapter } from './adapters/http';

const adapter = new HttpAdapter({
    host: 'localhost',
    port: 3000
});

async function sendContext(context: unknown) {
    await adapter.send(context);
}

async function receiveContext() {
    const received = await adapter.receive();
    // Process the received data
}

3. Error Handling

A unified error handling mechanism ensures the stable operation of the system under abnormal conditions.

import { AdapterError } from './errors';

try {
    await sendContext(context);
} catch (error) {
    if (error instanceof AdapterError) {
        console.error('Adapter error:', error.message);
    } else {
        console.error('Unexpected error:', error);
    }
}

4. Performance Optimization

Improves system performance through caching and asynchronous processing.

import { ContextCache } from './caching';

const cache = new ContextCache();

async function processContext(context: unknown) {
    try {
        const cached = await cache.get(context.id);
        if (cached) return cached;
        
        const validated = validateContext(context);
        // Process validated and cache
        cache.set(context.id, validated);
        return validated;
    } catch (error) {
        console.error('Processing error:', error);
        throw error;
    }
}

5. Monitoring and Logging

Integrates professional monitoring and logging tools for easy system maintenance.

import { Logger } from './logging';

const logger = new Logger('ContextProcessor');

async function processContext(context: unknown) {
    try {
        logger.info('Processing context with id:', context.id);
        // Processing logic
    } catch (error) {
        logger.error('Error processing context:', error);
        throw error;
    }
}

6. Security Measures

Ensures system security through authentication and data encryption.

import { Authenticator } from './security';

async function authenticate(user: User) {
    return await Authenticator.validate(user.id, user.password);
}
