Describe the bug
A clear and concise description of what the bug is.

To Reproduce
Steps to reproduce the behavior:

1. MacOS, have zsh as your shell and use lazy node (below)
2. try to run mcp dev server_module.py
3. See error:

2025-01-04 10:55:05,882 - cli - ERROR - npx not found or failed to load. Please ensure Node.js and npm are properly installed and your shell initialization files are correctly configured.
2025-01-04 10:55:05,883 - cli - ERROR - npx not found. Please ensure Node.js and npm are properly installed and added to your system PATH.

lazy node shell script:

# Add every binary that requires nvm, npm or node to run to an array of node globals
NODE_GLOBALS=(`find ~/.nvm/versions/node -maxdepth 3 -type l -wholename '*/bin/*' | xargs -n1 basename | sort | uniq`)
NODE_GLOBALS+=("node")
NODE_GLOBALS+=("nvm")
NODE_GLOBALS+=("npx")

# Lazy-loading nvm + npm on node globals call
load_nvm () {
  export NVM_DIR=~/.nvm
  [ -s "$NVM_DIR/nvm.sh" ] && . "$NVM_DIR/nvm.sh" # This loads nvm
  if [ -f "$NVM_DIR/bash_completion" ]; then
    [ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion" # This loads nvm bash_completion
  fi
}

# Making node global trigger the lazy loading
for cmd in "${NODE_GLOBALS[@]}"; do
  eval "${cmd}(){ unset -f ${cmd} >/dev/null 2>&1; load_nvm; ${cmd} \$@; }"
done

Expected behavior
A clear and concise description of what you expected to happen.

• mcp dev server runs, it runs if I manually change the command to subprocess and source my ~/.zshrc
