🔧 Quick Start

Claude Desktop Integration

This MCP server is fully compatible with Claude Desktop. See CLAUDE_DESKTOP_SETUP.md for installation instructions.

🔧 Quick Start

1. Setup Environment

Windows:

setup_env.bat

Manual:

cp .env.example .env
# Edit .env with your AWS credentials

2. Install Dependencies

pip install python-dotenv boto3 mcp

3. Test Configuration

python test_environment.py

4. Test AWS Connection

python simple_test/test_aws_access.py

🔐 Environment Variables

Key environment variables (see .env.example for full list):

# AWS Credentials
AWS_ACCESS_KEY_ID=your_access_key_here
AWS_SECRET_ACCESS_KEY=your_secret_key_here
AWS_DEFAULT_REGION=us-east-1

# Default Security Group
DEFAULT_SECURITY_GROUP_ID=sg-0f0df629567eb6344
DEFAULT_SECURITY_GROUP_NAME=whm-dev

# Description Format
DESCRIPTION_PREFIX=auto
DESCRIPTION_SEPARATOR=-
DESCRIPTION_TIMESTAMP_FORMAT=%Y%m%d-%H%M

📝 Usage Examples

Command Line Usage

Add a security group rule:

python simple_test/add_sg_rule_env.py '{
  "UserName": "john_doe",
  "UserIP": "203.0.113.45",
  "Port": "8080",
  "SecurityGroupID": "sg-0f0df629567eb6344",
  "ResourceName": "WebApp"
}'

With dry run:

python simple_test/add_sg_rule_env.py --dry-run '{...}'

Using different environment file:

python simple_test/add_sg_rule_env.py --env-file .env.production '{...}'

MCP Server with Claude Desktop

1. Configure Claude Desktop:

   • Copy configuration from mcp_server/claude_desktop_config_env.json
   • Add to %APPDATA%\Claude\claude_desktop_config.json

2. Restart Claude Desktop

3. Use in Claude:

   Add IP 192.168.1.100 to security group sg-0f0df629567eb6344 on port 8080
   

🛡️ Security Best Practices

1. Never commit .env files - Use .env.example as template
2. Use IAM roles when running on AWS infrastructure
3. Rotate credentials regularly
4. Minimal permissions - Only grant required EC2 permissions:
   • ec2:DescribeSecurityGroups
   • ec2:AuthorizeSecurityGroupIngress
   • ec2:RevokeSecurityGroupIngress

📊 Description Format

Rules are created with standardized descriptions:

{ResourceName} - {Port}-auto-{UserName}-YYYYMMDD-HHMM

Example: WebApp - 8080-auto-john_doe-20250711-1430

🧪 Testing

Test environment setup:

python test_environment.py

Test AWS connectivity:

python simple_test/test_aws_access.py

Test MCP server locally:

python mcp_server/server_env.py

🔍 Troubleshooting

Common Issues

1. Module not found:

   pip install python-dotenv boto3 mcp
   

2. AWS credentials error:

   • Check .env file exists and has correct values
   • Verify no extra spaces or quotes
   • Test with AWS CLI: aws sts get-caller-identity

3. Permission denied:

   • Ensure IAM user has required EC2 permissions
   • Check security group exists and is accessible

Debug Mode

Set environment variable:

MCP_LOG_LEVEL=DEBUG

📚 Advanced Usage

Multiple Environments

# Development
ENV_FILE=.env.dev python simple_test/add_sg_rule_env.py ...

# Production  
ENV_FILE=.env.prod python simple_test/add_sg_rule_env.py ...

Programmatic Usage

from config_manager import get_config
import boto3

# Load configuration
config = get_config()
aws_config = config.get_aws_client_config()

# Create EC2 client
ec2 = boto3.client('ec2', **aws_config)

# Use configuration values
description = config.format_description("App", "8080", "user")
