fnm multishell makes it unable to run npx MCP server in Claude Desktop

[piavgh]

You can try this to add the brave-search MCP server to Claude Desktop (Mac OS latest version): https://github.com/modelcontextprotocol/servers/tree/main/src/brave-search

The problem is: the npx path is changed every time a new shell session is opened (this also apply to Claude Desktop, each time you open it, it creates a new shell session)
If you tried which npx, each time it will show you a different path of npx as a random version here ~/.local/state/fnm_multishells

I want to disable multishell behavior like this. Is there any way?
Thanks
