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

Discovered this when trying to figure out why the Open in VLC browser extension was not able to find the node native client. I wasn't able to find a solution. Switched to nvm and set up auto-switching instead.

Here's my dirty workaround (create symlinks to fnm's default alias) - there should be better ways to do it.

#!/bin/bash

# Create or update the symlink to the current fnm Node version
sudo ln -sf /Users/sonle/.local/share/fnm/aliases/default/bin/node /usr/local/bin/node
sudo ln -sf /Users/sonle/.local/share/fnm/aliases/default/bin/npm /usr/local/bin/npm
sudo ln -sf /Users/sonle/.local/share/fnm/aliases/default/bin/npx /usr/local/bin/npx
sudo ln -sf /Users/sonle/.local/share/fnm/aliases/default/bin/corepack /usr/local/bin/corepack

echo "Node.js symlinks updated"
echo "node: $(node --version)"
echo "npm: $(npm --version)"
echo "npx: $(npx --version)"
echo "corepack: $(corepack --version)"
