MCP access from LIttlebird ai

Hi, I still have this problem. I have contacted Littlebird who assure me the problem is not theirs. I successfully attach Littlebird to many other MCPs. Is it possible for you to look at this, please? @samuelclay

Just to be clear, I use https://newsblur.com/mcp/

I get the error message: Server rejected the API token.

Do I need an API token? And if so, where do I find that?
