     Converts a temperature value from one unit to Celsius, Fahrenheit, and Kelvin.
 
-    This function takes a temperature value as a string and its unit, performs the conversion, and returns the equivalent temperatures in all three units as formatted strings. Designed for use in a Gradio interface and as an MCP tool.
+    This function takes a temperature value as a string and its unit, performs the conversion, and returns the equivalent temperatures in all three units as formatted strings in a dictionary. Designed for use in a Gradio interface and as an MCP tool.
 
     Args:
         temp (str): The temperature value as a string (e.g., '25', '-10.5'). Must be convertible to a float.
         unit (str): The unit of the input temperature. Must be one of 'Celsius', 'Fahrenheit', or 'Kelvin'.
 
     Returns:
-        tuple[str, str, str]: A tuple containing three strings:
-            - Temperature in Celsius (e.g., '25.00 °C') or 'Invalid' if input is invalid.
-            - Temperature in Fahrenheit (e.g., '77.00 °F') or 'Invalid' if input is invalid.
-            - Temperature in Kelvin (e.g., '298.15 K') or 'Invalid' if input is invalid.
+        dict[str, str]: A dictionary with three keys:
+            - 'celsius': Temperature in Celsius (e.g., '25.00 °C') or 'Invalid' if input is invalid.
+            - 'fahrenheit': Temperature in Fahrenheit (e.g., '77.00 °F') or 'Invalid' if input is invalid.
+            - 'kelvin': Temperature in Kelvin (e.g., '298.15 K') or 'Invalid' if input is invalid.
 
     Raises:
         ValueError: If the temp input cannot be converted to a float.
