I tried several mcp servers and only few of them were recognized. MCPAtlassian of them was recognized once and then stopped.
I tried to create my own server with mcp framework and I see it works when I am using npx @modelcontextprotocol/inspector but cursor keeps denied it.
I tried both sse and stdio. And I can use my server though @modelcontextprotocol/inspector but cursor does not see it, shows “Tools not found” message.
What is the protocol of cursor checking the server? How to debug?
