bug: My tool was not getting listed, Getting "Servers still loading"

### Checks

- [x] I have searched [github.com/aws/amazon-q-developer-cli/issues](https://github.com/aws/amazon-q-developer-cli/issues?q=) and there are no duplicates of my issue

### Operating system

WIndows

### Expected behaviour

My tool should get listed,

I configured mcp.json as
`{
"mcpServers": {
"ConfusingCalculator": {
"command": "uv",
"args": ["run", "/mnt/c/WorkFolder/Sample/MCP/weather/weather.py"],
"transport": "stdio"
}
}
}`

And the server logs

### Actual behaviour

My tool should get listed

### Steps to reproduce

_No response_

Comienza con la configuración de mcp.json mostrada y los registros del servidor de weather.py; después, reproduce la configuración de stdio en Windows y observa si ConfusingCalculator sigue mostrando “Servers still loading.”. Se considera terminado cuando la herramienta add configurada aparece correctamente en la lista en lugar de seguir no disponible.
