🚀 From Template to Your MCP Server

Interactive Setup

python quick_setup.py

The wizard will ask you:

• Server name (e.g., "weather-tools-server")
• Description (what your server does)
• Your branding (name, email, repository)
• Tool purpose (what kinds of tools you're building)

Your Files Are Updated

• config.py - All your settings in one place
• tools/custom_tools.py - Template for your tool implementations
• README.md - Updated with your project info

Add Your Tools

# In tools/custom_tools.py
async def my_awesome_tool_impl(param1: str, param2: int) -> Dict[str, Any]:
    # Your tool logic here
    return {"result": f"Processed {param1} with value {param2}"}

Deploy Anywhere

# Local development
python mcp_server.py

# Production with Docker
docker build -t my-mcp-server .
docker run -p 8080:8080 my-mcp-server

🛠️ Development

Code Quality Tools

Available Commands

Command	Description
pytest	Run all tests
pytest -m unit	Run unit tests only
pytest -m integration	Run integration tests only
black .	Format all Python files
isort .	Sort imports
mypy mcp_server/	Type checking
flake8 mcp_server/	Code linting

./build.sh	Build and test Docker image

🔧 Configuration

Environment Variables

Variable	Default	Description
MCP_SERVER_NAME	"template-server"	Server name identifier
MCP_TRANSPORT	"stdio"	Transport type (stdio, http, sse)
MCP_HOST	"0.0.0.0"	Host for HTTP transport
MCP_PORT	"8080"	Port for HTTP transport
WORKSPACE_PATH	"/workspace"	Base path for file operations

Security Configuration

⚠️ Important Security Notes:

• The default host 0.0.0.0 binds to all interfaces. For production, use 127.0.0.1 or a specific IP
• File operations are restricted to the WORKSPACE_PATH directory
• Command execution has timeout limits and input validation
• All file paths are validated to prevent directory traversal attacks
