Brand MCP Server (Python)

This provides an MCP server for accessing the brand Postgres database using Python.

Setup Instructions (Local)

Create a virtual environment and install dependencies:

python -m venv .venv
# Windows
.venv\Scripts\activate
pip install -r requirements.txt

Configure environment: Copy .env.example to .env and fill in your database credentials:
```
cp .env.example .env
```

Claude Desktop Configuration: On Windows, open your Claude configuration file located here: %APPDATA%\Claude\claude_desktop_config.json

Add the following configuration to run the server locally:

{
  "mcpServers": {
    "brand-db": {
      "command": "C:\\Users\\Mike\\Desktop\\Chumbak MCP\\brand-mcp-server\\.venv\\Scripts\\python.exe",
      "args": ["-m", "src.server"],
      "env": {
        "DB_HOST": "localhost",
        "DB_PORT": "5432",
        "DB_NAME": "brand_db",
        "DB_USER": "postgres",
        "DB_PASS": "password",
        "PYTHONPATH": "C:\\Users\\Mike\\Desktop\\Chumbak MCP\\brand-mcp-server"
      }
    }
  }
}

EC2 Deployment (Ubuntu)

If you are deploying this MCP server to an Ubuntu EC2 instance (e.g. Ubuntu 22.04 or 24.04), follow these steps to securely configure the server using the FastAPI implementation (src/server2.py).

1. Update and Install Dependencies

SSH into your EC2 instance and run the following commands to install Python 3 and Git:

sudo apt update && sudo apt upgrade -y
sudo apt install git python3 python3-pip python3-venv -y

2. Clone the Repository

git clone https://github.com/MiKecantdothis/MCPforGBL.git
cd MCPforGBL

3. Setup Virtual Environment & Install Packages

python3 -m venv .venv
source .venv/bin/activate
pip install -r requirements.txt

4. Create your Environment Variables

Since your secrets are safely .gitignore'd, you must create the .env file manually on the EC2 instance:

nano .env

(Paste your database credentials inside, save with Ctrl+O, Enter, and exit with Ctrl+X.)

5. Run the Server (HTTP/SSE)

To start the FastAPI HTTP server and keep it running in the background even after you close your SSH connection, use nohup:

nohup python3 -m src.server2 > server.log 2>&1 &

Note: Your FastAPI server will now be accessible via your EC2 instance's IP on port 8000. Important: Make sure you edit your instance's Security Group in the AWS console to allow Inbound TCP traffic on Port 8000.

6. Connect Claude Desktop to EC2

If you prefer not to expose Port 8000 publicly and want Claude Desktop to communicate securely via SSH to your newly launched EC2 instance, use the standard stdio configuration.

Open %APPDATA%\Claude\claude_desktop_config.json on your Windows machine and add:

{
  "mcpServers": {
    "brand-db-remote": {
      "command": "ssh",
      "args": [
        "-i", "C:/path/to/your/ec2-key.pem",
        "ubuntu@YOUR-EC2-PUBLIC-IP",
        "cd /home/ubuntu/MCPforGBL && source .venv/bin/activate && python3 -m src.server"
      ]
    }
  }
}

(This setup seamlessly securely tunnels Claude's requests via SSH directly into your EC2's standard input/output server!)
