Describe the bug (actual behavior)

Hi, I just updated to the latest version (1.3.0) and wanted to try the MCP server

my kafka-ui setup is using github SSO auth

This is the output of vscode:
2025-07-25 13:57:35.804 [info] Starting server my-mcp-server-00927cbd 2025-07-25 13:57:35.804 [info] Connection state: Starting 2025-07-25 13:57:35.808 [info] Starting server from LocalProcess extension host 2025-07-25 13:57:35.811 [info] Connection state: Running 2025-07-25 13:57:36.953 [info] 406 status sending message to https://kafka-ui.xxxx.com/mcp/sse, will attempt to fall back to legacy SSE 2025-07-25 13:57:37.943 [info] Connection state: Error 406 status connecting to https://kafka-ui.xxxx.com/mcp/sse as SSE: 2025-07-25 13:57:37.943 [error] Server exited before responding to initializerequest.

and this is the vscode config:
"my-mcp-server-00927cbd": { "url": "https://kafka-ui.xxxx.com/mcp/sse", "type": "sse" }

Is it supported? Thanks

Thanks for opening an issue, @miguellobato84. Currently, MCP endpoints do not support the OAuth flow. I recommend using the resourceserver configuration instead: configuration guide.

hi @germanosin, Could you provide an example configuration for the MCP endpoint using resource-server?
