{'content': [{'type': 'text', 'text': 'Error: Unknown tool: get_current_time'}], 'isError': False}

Describe the bug

When a specific action or request is made, the system returns a response with the content {'content': [{'type': 'text', 'text': 'Error: Unknown tool: get_current_time'}], 'isError': False}. The response indicates an error ("Error: Unknown tool: get_current_time"), but the isError flag is incorrectly set to False instead of True, which misrepresents the nature of the response.
