MCP Lambda Layer

🚀 MCP Lambda Server Introduction

MCP Lambda is a serverless service framework based on the AWS cloud, designed for rapidly building and deploying server - side applications. It leverages multiple AWS services such as AWS Lambda, DynamoDB, and IAM, aiming to simplify the development process and enhance the scalability and reliability of applications.

✨ Features

Core Components

1. Lambda Functions

   • Written in Node.js 20.x or higher.
   • Provide various functional modules, including user authentication, data processing, and API interfaces.

2. DynamoDB Tables

   • Store the core data of the application.
   • Automatically generate and manage table structures, supporting high - concurrency read and write operations.

3. IAM Roles

   • Assign permissions to Lambda functions and other AWS resources.
   • Ensure the principle of least privilege to improve security.

4. SQS Queues

   • Handle asynchronous tasks and message queues.
   • Support high - throughput and low - latency message transmission.

📦 Installation

Method 1: Through AWS Serverless Application Repository (SAR)

1. Visit the AWS Serverless Application Repository.
2. Search for "mcp - lambda - sam" provided by Mark Van Proctor.
3. Click "Deploy" to start the process.
4. Configure the parameters:
   • StackIdentifier: Assign a unique identifier to the MCP instance.
   • VpcEnabled: Set it to true if you need to deploy in a VPC.
   • VpcId and SubnetIds: Provide only when VpcEnabled is true.

Method 2: Using npx CLI

npx @markvp/mcp-lambda-sam deploy

This command will interactively prompt you to enter management configurations:

• Stack name (for multiple instances)
• AWS region
• VPC configuration (optional)

Method 3: Programmatic Usage

1. Install the package:

npm install @markvp/mcp-lambda-sam

2. Use the sample code to deploy:

import { deploy } from '@markvp/mcp-lambda-sam';

// Example usage
deploy();

Method 4: Local Development and Deployment

1. Install dependencies:

npm install

2. Perform local build and deployment:

npm run deploy

💻 Usage Examples

Development Guide

# Install dependencies
npm install

# Code check
npm run lint

# Execute tests
npm test

# Build the project
npm run build

Publishing to SAR

1. Package the application:

npm run package:sar

2. Publish to the repository:

npm run publish:sar

3. Set public access (only needed once):
   • Log in to the AWS console and navigate to the Serverless Application Repository.
   • Select the target application, click "Share" and choose "Public".
   • Apply the following sharing policy:

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Principal": "*",
            "Action": "serverlessrepo:CreateCloudFormationTemplate",
            "Resource": "arn:aws:serverlessrepo:${region}:${account-id}:applications/mcp-lambda-sam"
        }
    ]
}

🤝 Contribution Guide
