MCP Nodejs Debugger

🚀 MCP Node Debugging Guide

The MCP (MongoDB Connection Pool) node is used to manage the MongoDB connection pool. Here is a comprehensive guide on how to configure and use the MCP node.

🚀 Quick Start

📦 Installation

Before you start, make sure you have installed the following dependencies:

• Node.js and npm
• MongoDB Residency (Mongoose)

npm install mongoose mcp-node

💻 Usage Examples

Basic Usage

Here is an example code for creating a simple MCP instance using mcp-node:

const mcp = require('mcp-node');
const config = {
    url: 'mongodb://localhost:27017/test',
    options: {
        useNewUrlParser: true,
        useUnifiedTopology: true
    }
};

// Create an MCP instance
const db = new mcp(config);

// Connect to the database
db.connect().then(() => {
    console.log('Connected to MongoDB successfully');
}).catch(err => {
    console.error('Failed to connect to MongoDB:', err);
});

// Disconnect
process.on('exit', () => {
    db.disconnect();
});

Advanced Usage

You can use the following options to customize the behavior of the MCP node:

Configuration Parameters:

• url: MongoDB connection string.
• options:
  • useNewUrlParser: Use the new UrlParser.
  • useUnifiedTopology: Enable unified topology (default is true).
• poolSize: Connection pool size (default is 10).
• idleTimeoutMS: Idle timeout in milliseconds.
• connectTimeoutMS: Connection timeout in milliseconds.

Example Configuration:

const config = {
    url: 'mongodb://localhost:27017/test',
    options: {
        useNewUrlParser: true,
        useUnifiedTopology: true
    },
    poolSize: 20,
    idleTimeoutMS: 3600000, // 1 hour idle timeout
    connectTimeoutMS: 5000 // 5 seconds connection timeout
};

Database Operations

Here is an example code for performing database operations using the MCP node:

const mcp = require('mcp-node');
const config = {
    url: 'mongodb://localhost:27017/test',
    options: {
        useNewUrlParser: true,
        useUnifiedTopology: true
    }
};

// Create an MCP instance
const db = new mcp(config);

// Connect to the database
db.connect().then(() => {
    // Insert data
    const collection = db.db.collection('users');
    return collection.insertOne({ name: 'John', age: 30 });
}).then(result => {
    console.log('Inserted successfully:', result);
}).catch(err => {
    console.error('Operation failed:', err);
});

// Disconnect
process.on('exit', () => {
    db.disconnect();
});

Error Handling

const mcp = require('mcp-node');
const config = {
    url: 'mongodb://localhost:27017/test',
    options: {
        useNewUrlParser: true,
        useUnifiedTopology: true
    }
};

// Create an MCP instance
const db = new mcp(config);

// Connect to the database
db.connect().then(() => {
    // Insert data
    const collection = db.db.collection('users');
    return collection.insertOne({ name: 'John', age: 30 });
}).then(result => {
    console.log('Inserted successfully:', result);
}).catch(err => {
    console.error('Operation failed:', err);
});

// Disconnect
process.on('exit', () => {
    db.disconnect();
});

Advanced Features

Using Custom SSL Certificates

If you need to use custom SSL certificates for MongoDB connections, you can add the certificate paths to the configuration:

const config = {
    url: 'mongodb://localhost:27017/test',
    options: {
        sslCAFile: path.join(__dirname, 'ssl', 'ca.pem'), // Custom CA file
        sslCertFile: path.join(__dirname, 'ssl', 'client.pem'), // Client certificate
        sslKeyFile: path.join(__dirname, 'ssl', 'client-key.pem') // Client key
    }
};

Using Authentication

If you have enabled authentication in MongoDB, you can include the credentials in the connection string:

const config = {
    url: 'mongodb://username:password@localhost:27017/test',
    options: {
        useNewUrlParser: true,
        useUnifiedTopology: true
    }
};

Performance Tuning

Adjusting the Connection Pool Size

const config = {
    url: 'mongodb://localhost:27017/test',
    // Other configuration options...
};
