Implementation Reference
- src/unit_converter_mcp/server.py:62-76 (handler)MCP tool handler registered with @app.tool() that executes the temperature conversion by calling the core tool function and formats the response dictionary.
@app.tool() def convert_temperature( value: Annotated[float, Field(description="Temperature value to convert")], from_unit: Annotated[TEMPERATURE_UNIT, Field(description="Source unit")], to_unit: Annotated[TEMPERATURE_UNIT, Field(description="Target unit")], ) -> dict: """Convert temperature between units.""" converted_value = convert_temperature_tool(value, from_unit, to_unit) return { "original_value": value, "original_unit": from_unit, "converted_value": converted_value, "converted_unit": to_unit, "conversion_type": "temperature", } - Literal type definition for supported temperature units, used in the tool schema for input validation.
TEMPERATURE_UNIT = Literal["celsius", "fahrenheit", "kelvin"] - Core helper function implementing the temperature unit conversion logic via intermediate conversion to Celsius.
