AI Development Assistant MCP Server: Empowering AI Application Integration

Overview: What is AI Development Assistant MCP Server?

The AI Development Assistant MCP Server, designed specifically for Cursor, serves as a crucial adapter to enable advanced, AI-driven coding and design assistance through the Model Context Protocol (MCP). This project, while largely a tutorial demo, paves the way for real-world applications by integrating custom AI tools directly into the development workflow. Its primary strengths lie in offering features like code architecture creation, UI screenshot analysis, and code review functionalities, making it an invaluable asset for developers looking to streamline their coding processes with intelligent tools.

🔧 Core Features & MCP Capabilities

The core of this server lies in its ability to leverage Model Context Protocol (MCP) for integrating AI into the development process. MCP serves as a standardized interface that allows various AI applications, such as Claude Desktop and Continue, to interact seamlessly with specific data sources and tools. This server includes three primary features:

1. Code Architect: A reasoning LLM that generates plans and instructions for coding agents.
2. Screenshot Buddy: An image analysis tool powered by GPT models for UI design.
3. Code Review: Automated code review through Git diff integration.

These features not only enhance the functionality of AI tools but also improve the overall coding experience, ensuring developers can rely on intelligent AI to assist in their workflows.

⚙️ MCP Architecture & Protocol Implementation

The AI Development Assistant MCP Server is built using a modular architecture that adheres strictly to the Model Context Protocol (MCP). The protocol itself defines a series of standardized interactions between an MCP client and an MCP server. This project implements these standards through Node.js, providing a robust foundation for integration with various AI applications.

The MCP protocol flow can be visualized as follows:

    A[AI Application] -->|MCP Client| B[MCP Protocol]
    B --> C[MCP Server]
    C --> D[Data Source/Tool]

    style C fill:#f3e5f5
    style D fill:#e8f5e8

This diagram illustrates how the MCP client initiates interactions, leveraging the protocol to communicate with the server and ultimately access or manipulate data sources or tools.

Real-World Implementation

For instance, when using the Code Architect tool, an AI application (like Claude Desktop) can send a request through the MCP client, which then translates this into a command for node /path/to/your/project/build/index.js. This command triggers the generation of architectural plans and instructions by the server's backend logic.

🚀 Getting Started with Installation

1. Environment Setup

To begin, create an environment configuration file at src/env/keys.ts, where you can store API keys for services like OpenAI:

export const OPENAI_API_KEY = "your_key_here";
// Add any other keys you need

It's important to note that storing API keys directly in source code is only suitable for local development and learning purposes. For production use, consider leveraging environment variables or secure vaults.

2. Installation

To install the dependencies, run one of the following commands:

npm install
# or
yarn install

3. Development & Build Commands

For building and running the server in development mode:

# Build the server
npm run build-only

# Development mode (watch for changes)
npm run dev

# Run the server
npm run start

# Deploy with PM2
npm run pm2

# Other PM2 commands
npm run stop      # Stop the server
npm run restart   # Restart the server
npm run logs      # View server logs
npm run status    # Check server status

These commands provide a robust development environment and allow for smooth deployment using PM2, a production process manager that ensures your application runs continuously.

💡 Key Use Cases in AI Workflows

Example: Code Architecture Generation

Imagine you're developing a web application. The Code Architect tool can be triggered to generate architectural plans based on the proposed feature or module. This automation not only speeds up the initial design phase but also ensures that the codebase is structured coherently from the start.

// Example invocation of Code Architect
const architectTool = new ArchitectTool();
architectTool.generatePlan(moduleName);

Example: UI Screenshot Analysis

When working on a user interface, the Screenshot Buddy tool can analyze design screenshots to provide context-aware feedback. This integration ensures that designers receive relevant suggestions based on both static and dynamic UI elements.

// Example invocation of Screenshot Buddy
const screenshotTool = new ScreenshotTool();
screenshotTool.analyzeScreenshot(pathToScreenshot);

🔌 Integration with MCP Clients

This project is designed to be used as a standard MCP server for Cursor. Here's how you can integrate it:

1. Open Cursor and navigate to Cursor Settings > Features > MCP.
2. Add New MCP Server: Fill out the form with:
   • Name: AI Development Assistant
   • Type: stdio
   • Command: node /path/to/your/project/build/index.js

After adding the server, ensure it's listed under "Available Tools" in the MCP section. If not, refresh the page.

📊 Performance & Compatibility Matrix

The AI Development Assistant MCP Server is compatible with a range of mainstream MCP clients. Here’s a compatibility matrix:

MCP Client	Resources	Tools	Prompts
Claude Desktop	✅	✅	✅
Continue	✅	✅	✅
Cursor	❌	✅	❌

🛠️ Advanced Configuration & Security

MCP Configuration Sample

For integrating the server with your MCP client, you might need to update its configuration file. Here’s a sample configuration snippet:

{
  "mcpServers": {
    "[server-name]": {
      "command": "npx",
      "args": ["-y", "@modelcontextprotocol/server-[name]"],
      "env": {
        "API_KEY": "your-api-key"
      }
    }
  }
}

This snippet ensures that your MCP client can access the necessary tools and data seamlessly.

Security Note

It is crucial to securely manage API keys, especially in production environments. Avoid storing sensitive information such as OpenAI keys in source code or configuration files directly. Use environment variables, secure vaults, or other secure methods for handling API credentials.
