Describe the problem/error/question
I’m using the MCPClientNode in n8n v1.95.3 and configured it with Bearer Token authentication. However, the outgoing HTTP request does not include the Authorization header at all.
I confirmed this by checking the request headers via a custom Cloudflare Worker that logs incoming requests — and the Authorization header is completely missing.
I also tried sending the same request using the regular HTTP Request node, and it includes the Authorization header as expected. So the issue seems specific to the MCPClientNode.
Is this a known bug? Or is there some additional configuration required to make it send the header?
