Rendering all messed up when adding an mcp server using /mcp

### Describe the bug


I'm trying to add an mcp server and the rendering is all messed up.

### Affected version

v1.0.69-0

### Steps to reproduce the behavior

run /mcp add and try to add the server. I tried to name it the same as the url of the remote mcp if that matters. I am on windows using vanilla cmd to launch the cli.

### Expected behavior

_No response_

### Additional context

_No response_

Start by reproducing the issue with the /mcp add command on Windows using vanilla cmd, as described, and compare the rendering when naming the server after the remote MCP URL. Inspect the CLI path handling /mcp add; done means the server can be added without the terminal rendering becoming corrupted.
