How to alias your npx npm node globally for MCPs to work

.zshrc

# your .bashrc or .zshrc shit...

npx() { command $HOME/.nvm/versions/node/$(node --version)/bin/npx "$@"; }
npm() { command $HOME/.nvm/versions/node/$(node --version)/bin/npm "$@"; }
node() { command $HOME/.nvm/versions/node/$(node --version)/bin/node "$@"; }

# save and run "source ~/.bashrc" or "source ~/.zshrc"

Then you no longer need to use pinned versions of your nvm installation bin path

{
  "servers": {
    "chrome-devtools": {
      "command": "~/.nvm/versions/node/v22.13.1/bin/npx",
      "args": ["-y", "chrome-devtools-mcp@latest"]
    }
  }
}

Or dynamic version (it also works, but it's awful)

{
  "servers": {
    "chrome-devtools": {
      "command": "~/.nvm/versions/node/$(node --version)/bin/npx",
      "args": ["-y", "chrome-devtools-mcp@latest"]
    }
  }
}

Just use it normally

{
  "servers": {
    "chrome-devtools": {
      "command": "npx",
      "args": ["-y", "chrome-devtools-mcp@latest"]
    }
  }
}
