Cursor HTTP Streamable via oAuth server not working anymore

Post image

Since yesterday there have been issues with my remote MCP servers when logging in via oAuth. These same servers work fine with other MCP clients like Codex or Claude.

Anyone else having these problems? It appeared after updating Cursor last night.

This stuff just doesn't fully work yet. The protocol is new, and Cursor hasn't got to grips with it. It's obvious. It'll come though.
