What's Wrong?

I have tried to connect the NetSuite connector in Claude Desktop app and was able to ask a couple questions, but then every time since I get some sort of response equivalent with "Unfortunately, the NetSuite MCP tool doesn't appear to have loaded any useful tools..." or "The NetSuite MCP server connected to your account still isn't exposing any NetSuite-specific tools on my end, regardless of what's been configured within NetSuite itself."

What Should Happen?

I'd like it to be able to answer the questions or run the requested analysis.
