This is likely a shell PATH inheritance issue i.e. gui-launched apps on macOS don’t get your login-shell’s PATH, so the mcp commands (e.g. npx) aren’t on their search path. one workaround is to launch Void from a shell so it picks up your PATH, for example: open -a Void. Alternatively you can add your Node/MCP paths explicitly in argv.json. Pls see #701 which has more context around this.

Use the full path to npx or uvx

Hello everyone, the problem is that when the app is run in another environment, in order for it to work, people use open -a Void, but there are two other solutions:

1. Launch Void in correct environment when starting the Osx: nano ~/Library/LaunchAgents/com.void.wrapper.plist

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
  <key>Label</key> <string>com.void.wrapper</string>

  <key>ProgramArguments</key>
  <array>
    <string>/usr/bin/open</string>
    <string>-a</string>
    <string>Void</string>
  </array>

  <key>EnvironmentVariables</key>
  <dict>
    <key>PATH</key>
    <string>/opt/homebrew/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin</string>
  </dict>

  <key>RunAtLoad</key> <true/>
</dict>
</plist>

---

2. Permanent: sudo launchctl config user path "$(brew --prefix)/bin:$(npm config get prefix)/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin" Reboot OSX and when you open Void, it will recognise the npx and the mcp will work.

---

3. Permanent 2, edit the zprofile. nano ~/.zprofile

At the end of the file, add the paths where your npx is located.

export PATH="/usr/local/bin:/Users/too-rzy/.nvm/versions/node/v22.17.1/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:$PATH"

Happy Coding 🥳 Regards
