Creating a New Tool

Create a new Python file in src/claude_tools/:

## src/claude_tools/my_tool.py
def my_awesome_function(param: str) -> str:
    """Description of what this tool does.
    
    Args:
        param: Description of the parameter
        
    Returns:
        A string with the result
    """
    result = f"Processed: {param}"
    return result
    
def register_my_tools(mcp):
    """Register all my tools with the MCP server."""
    mcp.tool()(my_awesome_function)

Import and register your tool in __init__.py:

## In src/claude_tools/__init__.py
from .calculator import register_calculator_tools
from .datetime_tool import register_datetime_tools
from .weather import register_weather_tools
from .my_tool import register_my_tools  # Add this line

def register_all_tools(mcp):
    register_calculator_tools(mcp)
    register_datetime_tools(mcp)
    register_weather_tools(mcp)
    register_my_tools(mcp)  # Add this line
