Describe the bug

At the moment, when my server is emitting logs on stderr, I have no way of finding them in the inspector.

To Reproduce
Steps to reproduce the behavior:

  1. Create an MCP server that serve in stdio mode and that emit on stderr for logs
  2. Launch MCP inspector targeting this MCP server in stdio mode
  3. Generate activity to create logs on the MCP server side
  4. Notice that those logs are missing from the MCP inspector interface or the terminal where it is launched

Expected behavior

I would expect the stderr of my server to be captured somewhere and displayed in the MCP inspector part
