With HTTPS And GitHub OAuth

This project is a secure local MCP server built with Node.js and Express. It features HTTPS encryption using self-signed certificates, GitHub OAuth authentication, and additional security measures like rate limiting and HTTP header protection.

Features

• HTTPS Encryption: Ensures secure communication between clients and the server.
• GitHub OAuth Authentication: Allows users to log in using their GitHub accounts.
• Rate Limiting: Protects against abuse and denial-of-service (DoS) attacks.
• Secure Session Management: Uses express-session with secure cookies.
• HTTP Header Security: Implements helmet to protect against common vulnerabilities.

Prerequisites

Before you begin, ensure you have the following installed on your system:

• Node.js (v16 or later)
• npm (comes with Node.js)
• OpenSSL (for generating SSL certificates)

Setup Instructions

Step 1: Clone the Repository

Clone this repository to your local machine:

git clone https://github.com/omar-steam/MCP-Server-with-HTTPS-and-GitHub-OAuth.git cd mcp-server

Step 2: Install Dependencies

Install the required npm packages:

npm install

Step 3: Generate SSL Certificates

Generate self-signed SSL certificates using OpenSSL:

openssl genrsa -out key.pem 2048 openssl req -new -key key.pem -out csr.pem openssl x509 -req -days 365 -in csr.pem -signkey key.pem -out cert.pem

This will create the following files in your project directory:

• key.pem: Private key
• cert.pem: Self-signed certificate

Step 4: Configure Environment Variables

Create a .env file in the root of your project and add the following variables:

CLIENT_ID=your-github-client-id CLIENT_SECRET=your-github-client-secret REDIRECT_URI=https://localhost:3000/auth/callback SESSION_SECRET=your-session-secret

Replace your-github-client-id and your-github-client-secret with the credentials from your GitHub OAuth App.

Step 5: Start the Server

Run the server: node server.js

You should see:

Secure server running on https://localhost:3000

Usage

Accessing the Server

Open your browser and navigate to:

https://localhost:3000

Authentication via GitHub

1. Visit /auth to start the GitHub authentication process:

https://localhost:3000/auth

2. After successful login, you’ll be redirected to /success.
3. If authentication fails, you’ll be redirected to /failure.

Protected Routes

Access /secure-data to test a route that requires authentication:

https://localhost:3000/secure-data

If you’re not authenticated, you’ll see a 401 Unauthorized error.

Troubleshooting

Port Already in Use (EADDRINUSE)

If port 3000 is already in use, stop any processes using it or change the port in server.js.

To find and kill processes using port 3000:

netstat -ano | findstr :3000 taskkill /PID <PID> /F

Certificate Warnings in Browser

Self-signed certificates are not trusted by browsers. For production, use a trusted Certificate Authority like Let’s Encrypt.

Notes for Customization:

1. Replace placeholders like your-github-client-id with your actual credentials.
2. Update the repository URL (git clone) with your GitHub repository link if you’re hosting this code.
