Describe the problem/error/question
I try to connect n8n platform with my mcp server. I run the mcp server locally using my localhost. I try to connect using node mcp client that I installed in community. and I set the connection to SSE (Server-Sent Events). I already try to hit the endpoint using postman and it works, but when I try to run it in n8n, it shows the error besides my mcp server is totally running in my local. what should I do?
What is the error message (if any)?Problem in node ‘MCP Client‘
Failed to execute operation: Failed to connect to MCP server: SSE error: Non-200 status code (422)
