When a user attempts to add a new REST tool and the configuration is invalid (example: Invalid Tool Name ), the system displays a generic "Validation Failed" error message. This message does not provide any specific details about which part of the configuration is incorrect, making it difficult and time-consuming for the user to troubleshoot and correct the issue.

Container log says:
"ERROR [mcpgateway] ValidationError in admin_add_tool: 1 validation error for ToolCreate
name
Value error, Tool name must start with a letter and contain only letters, numbers, and underscore [type=value_error, input_value='Langsmith Workspaces', input_type=str]"
