Cursor MCP requests do not honour API-key provision to sse (only stdio works)

Bug Reports
1

This is how MCP server configs are supposed to provide API keys to SSE endpoints:

{
    "mcp": {
      "type": "sse",
      "url": "https://example.com/sse",
      "headers": {
        "Authorization": "Bearer YOUR_API_TOKEN"
      }
    }
}

But right now, your MCP implementation only understands “env” variables for stdio mcp servers.

Please add the required support for sse

Hey,
when can we expect these fixes to come out? I apologise for asking such question, but I’m not sure if I should start working on a workaround for this issue, or just wait for the update to come out, since this issue is currently blocking us.
Thanks in advance
