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
- Restart the server and your new tool is ready to use!
